Description

  The present invention relates to a technology (RFID Radio Frequency Identification) that reads and writes data using radio waves and recognizes an object without contact. More specifically, the present invention relates to a paper in which a non-contact type IC tag, which is a device using RFID, is inserted in a paper layer of paper, and a method for manufacturing the same.

  To cope with the increase in the amount of information and the rewriting of records in cards such as passports, insurance cards, and membership registration cards for confirmation and identification of users in various public facilities and other facilities such as libraries and transportation facilities In addition, a non-contact type IC tag in which a resonance circuit such as an antenna coil or a capacitor and an IC chip are mounted is used. As such an IC card substrate, plastics such as polyester resin, ABS resin, or vinyl chloride resin are mainly used.

  In order to promote the versatility of these IC cards, there is a demand for thinner and lower cost cards. From such a viewpoint, a paper IC card has been proposed in view of demands for easy processing such as printing and a significant reduction in cost.

  For example, a non-contact type IC doug sandwiched between card sheets (for example, see Patent Document 1), and a card sheet surface printed with an antenna pattern using conductive ink have been proposed ( For example, see Patent Document 2.)

  In addition, for the purpose of preventing counterfeiting by replacing the non-contact type IC tag of the paper IC card, a paper IC card in which the IC tag is inserted between the layers of the paper when paper is made (for example, patent document) 3 or 4), and anti-counterfeit paper (see, for example, Patent Document 5 or Patent Document 6) encased in a paper layer.

  Further, the non-contact type IC tag is also made thinner, and a non-contact type IC tag having a thickness of 60 to 70 μm (see Patent Document 7) has also been proposed.

  In a conventional paper IC card in which a non-contact type IC tag is inserted between paper layers at the time of conventional papermaking, the surface of the inserted paper has a swelling or uneven gloss due to the IC tag. As a result, the presence of the IC tag was visually observed, surface smoothness was inferior, printability and designability were inferior, and water resistance and dimensional stability were inferior.

  In addition, a paper IC card in which a conventional non-contact type IC tag is encased in a paper layer may cause distortion in the paper mat formed on the wire when the IC tag is encased in the paper layer. When the application is intended for relatively small applications such as card-sized dimensions, the non-contact type IC tag must be squeezed into the paper layer in the width direction of the paper machine, and the inlet, bat, Or block the flow of diluted stock in the pound, disturb it, or generate stains, which may cause poor paper formation, streaks and stains, and reduce surface smoothness, printability and design. In addition, the water resistance and dimensional stability were inferior, and there were major obstacles in practical use.

  In addition, in the case of paper IC cards or anti-counterfeit printing paper, there is a concern that the function of receiving and transmitting / receiving is stopped due to metal corrosion of the IC tag during long-term use.

  In addition, when a paper is manufactured by simply swiping a non-contact type IC tag on a general paper / paperboard machine, troubles of stopping the transmission / reception function frequently occur in the non-contact type IC tag that has been tucked into the paper. I found that there was a big problem that caused the missing number.

  Accordingly, a first object of the present invention is to provide a sheet that suppresses the occurrence of swelling or uneven glossiness due to the IC tag on the surface of the sheet by interposing into the paper layer without destroying the non-contact type IC tag. It is to be. That is, it is to provide a practical paper that is excellent in surface smoothness, printability and designability, and excellent in water resistance and dimensional stability, without the presence of an IC tag. The second object of the present invention is a method for producing a paper in which a non-contact type IC tag is inserted in a paper layer, without significantly changing a general paper / paperboard machine, It is another object of the present invention to provide a paper manufacturing method in which a non-contact type IC tag can be stably operated even after the non-contact type IC tag is destroyed without being destroyed.

That is, the paper obtained by the method for producing a paper in which the non-contact type IC tag according to the present invention is encased constitutes a multi-layer paper base material composed of two or more layers in the paper layer of the paper base material made of one layer. A non-contact type IC tag is inserted in at least one of the paper layers to be manufactured, and the pressurization of each pressurization device of the paper machine is produced with the linear pressure exceeding 0 kgf / cm and not more than 45 kgf / cm. The sizing degree of the paper base material or the multilayer paper base material according to the Steecht method defined in JIS P 8122: 2004 (hereinafter referred to as “Steecht sizing degree”) is 0.0093 × (basis weight) ^ 2. 00 seconds or more, the cold water extraction pH specified in JIS P 8133: 1998 of the paper base material or the multilayer paper base material exceeds 6.2, and all of the paper base material or the multilayer paper base material Chlorine content is 400 pm or less, and the JIS P of the paper substrate or the multilayer sheet substrate 8144: water-soluble chloride content defined by 1998 is equal to or less than 80 ppm. By inserting the non-contact type IC tag into the paper layer, the occurrence of swelling or uneven gloss due to the IC tag is less than when the non-contact type IC tag is inserted between the paper layers. Here, the thickness of the paper base or multilayer paper base specified by JIS P 8122: 2004 is 0.0093 × (basis weight) ^ 2.00 seconds or more so that the paper thickness does not return. Further, the presence of the non-contact type IC tag in the paper is not clear, and the anti-counterfeiting or design property is excellent. In addition, as the meaning which the term of a paper base material or a multilayer paper base material represents, the part of the paper base material in the coated paper which coated the coating composition containing a pigment on the surface, or the part of a multilayer paper base material is included. . Of course, it includes a paper base portion or a multilayer paper base portion of non-coated paper (the same applies hereinafter). In the paper layer of the neutral paper satisfying all the conditions of the cold water extraction pH, the total chlorine content of the paper base material or the multilayer paper base material and the water-soluble chloride content specified in JIS P 8144: 1998 By disposing the contact type IC tag, the non-contact type IC tag can be stabilized and operated. This is particularly effective in the case of a non-contact type IC tag in which an antenna coil, a wiring pattern, an IC chip and the like are mounted on an insulating film that is not sealed with a sealant, and an IC tag with a built-in antenna.

In the paper obtained by the paper manufacturing method in which the non-contact type IC tag according to the present invention is encased, the coating composition mainly composed of a pigment and an adhesive is coated on one side and / or on both sides with a coating amount of 5 to 15 g on one side. Includes paper coated at / m ² . The printability and designability of the paper can be further improved.

In the paper obtained by the method for producing a paper in which the non-contact type IC tag according to the present invention is inserted, the paper is individually sold or is put together with the tape to which the non-contact type IC tag is attached at a predetermined fixed position in the paper layer. Including the case of being included. Whether the contactless IC tag is a single product or the tape is used as a guide, the contactless IC tag is disposed at a predetermined position.

The method for producing a paper in which the non-contact type IC tag according to the present invention is engraved uses a neutral papermaking material using ECF bleached chemical pulp as a raw material pulp fiber, and a paper base or a multilayer paper base JIS. The step of adding a sizing agent in such an amount that the degree of sizing by the Steecht method specified in P 8122: 2004 is 0.0093 × (basis weight) ^ 2.00 seconds or more, and the wire part of the paper machine A step of inserting a non-contact type IC tag into a paper mat that is being formed on a wire, a step of obtaining a wet paper of a paper substrate consisting of one layer or a multilayer paper substrate consisting of two or more layers, and the paper machine characterized in that it and a step of pressing in the following 45 kgf / cm beyond the linear pressure 0 kgf / cm pressurization of the pressure device. By inserting the non-contact type IC tag into the paper mat that is being formed, the non-contact type IC tag can be easily placed in the paper layer without causing distortion in the paper layer. The destruction of the IC tag can be prevented. Further, by including the step of adding the sizing agent, the paper thickness does not return, the presence of the non-contact IC tag in the paper is not clarified, and a paper excellent in forgery prevention and design properties can be obtained. The use of a neutral papermaking material using ECF bleached chemical pulp as a raw material pulp fiber provides an environment in which a non-contact IC tag that is weak against acid can be operated stably. This is particularly effective in the case of a non-contact type IC tag in which an antenna coil, a wiring pattern, an IC chip and the like are mounted on an insulating film that is not sealed with a sealant, and an IC tag with a built-in antenna.

  In the method for manufacturing a paper in which the non-contact type IC tag is inserted according to the present invention, the step of inserting the non-contact type IC tag includes the non-contact type that is attached to a continuous continuous tape at a predetermined interval. It is preferable that it is a step of rolling the mold IC tag into the paper mat that is being formed together with the continuous tape. The non-contact type IC tag can be inserted into the paper layer of the paper base material with a predetermined interval precisely. Thus, for example, when a card having a non-contact type IC tag is manufactured, it is possible to reduce the paper base material to be discarded.

  In the method for manufacturing a paper in which the non-contact type IC tag is inserted according to the present invention, the step of inserting the non-contact type IC tag includes the step of inserting the tip of the non-contact type IC tag introduction tube into the paper mat that is being formed. It is preferable to dispose the non-contact type IC tag at predetermined intervals using water or diluted paper as a carrier. Of course, when a non-contact type IC tag is rolled in using the continuous tape, even when a non-contact type IC tag is rolled into a paper mat that is being formed as a single unit, a certain time is required from a desired location. In this case, the non-contact type IC tag can be inserted without causing any distortion in the paper layer at a precise interval.

  Further, in the method for manufacturing a paper in which the non-contact type IC tag is inserted according to the present invention, the paper machine is a multilayer paper machine, and the step of inserting the non-contact type IC tag includes: In this case, the non-contact type IC tag adjacent to each other is included in a different paper layer. When it is necessary to swipe non-contact type IC tags at a high density, such as when the size of the finished card is small, the interval between the non-contact type IC tag introduction tubes can be increased. As a result, the water flow of the diluted stock fed into the pound or bat is not blocked and disturbed, and the paper is neither thick nor thin, streaks, etc., and the formation is not extremely inferior. Further, the paper material is accumulated on the non-contact type IC tag introduction tube, so that the paper does not become dirty and become dirty.

In the method for producing a paper in which the non-contact type IC tag according to the present invention is encased, a coating composition mainly composed of a pigment and an adhesive is applied to one side and / or both sides of the paper at a coating amount of 5 to 15 g / m on one side. ² It is preferable to further have a step of coating with.

  The present invention relates to a paper in which a non-contact type IC tag is inserted in a paper layer of a single-layer paper base material or in at least one paper layer of a multi-layer paper base material composed of two or more layers. In addition, since it has the same surface properties and paper layer uniformity as general printing paper, it is excellent in printability and design. Furthermore, since it is excellent in dimensional stability and water resistance, it is practical. Further, in the method for manufacturing paper in which the non-contact type IC tag according to the present invention is inserted, the non-contact type IC tag is destroyed without significantly changing a general paper / paperboard machine. There is nothing. Furthermore, there is no possibility that the non-contact type IC tag stops functioning even after the paper is used, and the IC tag is not missing.

  Hereinafter, the present invention will be described in more detail with reference to embodiments, but the present invention is not construed as being limited to these descriptions. FIG. 1 is a schematic cross-sectional view showing an embodiment of a sheet in which a non-contact type IC tag according to the present embodiment is inserted, in which (a) is a sheet composed of one sheet layer, (b) Is the case of a sheet of multiple paper layers. As shown in FIG. 1A, the paper in which the non-contact type IC tag according to the present invention is inserted is inserted into the paper layer of the paper base material composed of one paper layer 13. Be rare. Alternatively, as shown in FIG. 1B, the non-contact type IC tag 1 is provided in at least one paper layer 3b among the paper layers 13a, 13b, and 13c constituting the multilayer paper base material composed of two or more paper layers. It will be rubbed in. The non-contact type IC tag is inserted into the paper layer without causing distortion in the paper layer.

  The non-contact type IC tag inserted into the paper layer is, for example, a metal layer such as copper or aluminum having a thickness of 18 to 50 μm laminated on one side of an insulating film having a thickness of 5 to 15 μm made of PET, PEN, PI or the like. The laminated plate is patterned to form an antenna coil and a wiring pattern, and a film capacitor, an IC chip mounted and integrated, or a thermosetting resin such as an epoxy resin, or a hot melt such as polyester. There is an IC doug with a thickness of 60 to 70 μm sealed with resin. Also included are coil-on-chip or antenna built-in IC tags in which an antenna coil is provided on an IC chip. Moreover, the case where the resonance tag which provided only the antenna coil in the said insulating film, or the wire-shaped antenna is included in the paper in which the non-contact-type IC tag which concerns on this embodiment was inserted.

  Hereinafter, while explaining a method of manufacturing a paper in which the non-contact type IC tag according to the present embodiment is inserted, characteristics of the paper will be described together.

  In the method of manufacturing a paper in which the non-contact type IC tag according to the present embodiment is inserted, the non-contact type IC doug is used as a paper material without making a major change to a paper machine on which general paper and paperboard are manufactured. It is an invention relating to interleaving into a paper layer in the middle of mat formation. Then, it is necessary to form a sheet without destroying the non-contact type IC tag in the subsequent paper making process. The flow of a general paper and board machine is shown in FIG. Based on this flow, the pressurization condition applied to the paper in each part, which is a major factor of destruction of the non-contact type IC tag, will be described.

  First, fibers such as pulp, which is a main raw material, and chemicals such as a sizing agent, a sulfuric acid band, a filler, and a dye are mixed in paper stock adjustment, and the paper stock or paper stock stock is adjusted to a concentration of about 3%.

  The stock is diluted to a concentration of 0.1 to 0.6%, and a specified amount corresponding to a paper having a predetermined basis weight is sent to the wet part and scraped off with a wire. There are three types of paper scraping methods depending on the type of wire: a long net, a circular net, and an inclination, which are used alone or in combination. This part is also called a wire part. The wet paper web at the outlet of this part is around 90%.

Next, wet paper with a moisture content of about 90% is sent to the press part and slowly squeezed to increase the efficiency of drying by heating in the next stage. The main purpose of this press part is dehydration of wet paper, but the wet paper surface is rough, and there are also wire marks and felt marks, which are corrected and made smoother, and the density of the paper is increased. Increasing physical strength is also a function. Since the wet paper moisture entering the press part is as high as about 90%, if the pressure is rapidly increased as it is, various troubles such as crushing, swelling and delamination of the wet paper occur. It is gradually dehydrated with a stepped baby press and dehydrated with a main press such as 4 to 5 suction rolls and grooved rolls. The wet paper web moisture at the press part outlet is about 52-60%. Table 1 shows the press line pressure (kgf / cm) and wet paper moisture of the press part in general paper and board production. In the manufacture of general paper and paperboard, wet paper is squeezed with a maximum press linear pressure of 110 kgf / cm. Table 1 illustrates two types of pressure patterns.

  Next, in the dry part, the wet paper having a water content of about 52 to 60% at the outlet of the press part is dried to a water content of about 5%. This part consists of a cylinder dryer or Yankee dryer whose surface temperature is heated to about 100-135 ° C. by steam. In the middle of the dry part, there is provided a size press for applying a 3 to 10% strength solution of a paper strength enhancer such as starch or PVA (polyvinyl alcohol) to the paper for the purpose of enhancing the surface strength of the paper. Usually, a paper strength enhancer solution is applied to paper at a linear pressure of about 30 to 40 kgf / cm.

  Paper that has been dried to a moisture content of about 5% and has come out of the dryer part has a rough surface and a soft tissue, so the surface is smooth, the texture is fine, and the calender is used to achieve a predetermined paper thickness. It is processed. In general, chilled rolls having a hardened chilled layer on the outer surface are used. A soft calendar using an elastic roll is also used. Usually, it is processed at a linear pressure of about 55 to 65 kgf / cm.

  The paper up to the calendar part has been made of continuous paper, but at the final stage of the paper machine, this continuous paper is wound up as it is (reel) or cut into the specified dimensions in plain format ( cutter). In addition, the reel that has been wound as it is is cut again by a winder into a flat sheet having a specified size by a small roll or cutter having a specified width.

  In this way, in general paper / paperboard paper machines, various papers are used to dehydrate wet paper or to improve the smoothness of the paper surface and to make the paper thickness uniform for imparting printability. The equipment which pressurizes is provided. When a non-contact type IC tag is simply squeezed into a paper with a general paper / paperboard machine, the non-contact type is caused by destruction of the IC chip itself by pressurization or destruction of the contact between the antenna coil and the IC chip of the non-contact type IC tag. IC tag malfunction occurs. In order to obtain a paper in which the non-contact type IC tag is inserted without causing a functional failure of the non-contact type IC tag, the pressurization of each pressurizing device of the paper machine is set to the linear pressure of 0 kgf. The present inventors have found that it is necessary to exceed 45 cmf / cm beyond / cm. Further, in addition to this condition, it is preferable that the linear pressure is 70% or less during normal paper / board manufacture. On the other hand, in order to maintain the printability of the paper containing the non-contact type IC tag of the present invention, in particular, the printing smoothness at the same level as the quality of general printing paper and board, The linear pressure of the press exceeds 0% of the linear pressure during normal production of general paper and paperboard, that is, pressurizes a little rather than emptying each pressurizing device of the press part, preferably a linear pressure of 30% or more It was found that it was necessary to pressurize with That is, without modifying the general paper / paperboard machine, there is no trouble of stopping the function of the non-contact type IC tag, and the same printability as that of general paper / paperboard is obtained. The present inventors have found that this can be achieved by setting the linear pressure of a pressure device used in a general paper / paperboard paper machine to more than 0 kgf / cm and not more than 45 kgf / cm. Further, in addition to this condition, the pressurization of each pressurization facility may be more than 0% to 70%, preferably 30% to 70%.

Further, the thickness of the non-contact type IC tag currently provided is 60 to 150 μm, and this thickness is equivalent to 50 to 130 g / m ² when the basis weight of the paper is used. As shown in FIG. 3, when a non-contact type IC tag is inserted between layers of laminated wet paper (about 90% moisture), the IC tag is inserted at the place where the IC tag is inserted. The density of the paper layer is higher than that of the unexposed portion, and as a result, the gloss of only the portion increases. Further, when the water resistance of the laminated paper is particularly weak, the paper thickness is returned and the paper thickness is increased only at the portion where the non-contact type IC tag is inserted. On the other hand, as shown in FIG. 4, when the non-contact type IC tag is inserted into the sample mat in the middle of the paper mat formation, the paper layer at the part where the non-contact type IC tag is inserted and the part where it is not. There is almost no difference in density, and no distortion occurs in the paper layer. Furthermore, the non-coated paper or the paper before coating with the pigment-containing paint has a Steecht size defined by JIS P 8122: 2004 of 0.0093 × (basis weight) ^ 2.00 seconds or more, preferably Is 0.0212 × (basis weight) ^ 1.90 seconds or more, so that there is no return of paper thickness and the presence of non-contact type IC tags in paper is not clarified. Paper with a non-contact type IC tag excellent in the above can be obtained. Note that “basis weight” in the above formula represents “basis weight of one layer of non-coated paper” in the case of a single-layer paper base unless otherwise specified, and in the case of a multilayer paper base consisting of two or more layers Represents “total basis weight of uncoated paper”.

  In addition, the paper IC card has a problem that water resistance is weak, dimensional stability is poor, and paper wrinkling and curling occur. 0.0093 × (basis weight) ^ 2.00 seconds or more, the degree of steecht stipulated in JIS P 8122: 2004 of the paper before applying the coating composition containing non-coated paper or pigment, Preferably, by making 0.0212 × (basis weight) ^ 1.90 seconds or more, it is possible to obtain non-coated paper and non-contact type IC tags without coated paper curled or non-coated IC tags. did it.

Further, a coating composition mainly composed of a pigment and an adhesive is applied on one side and / or on a paper in which a non-contact type IC tag is inserted using a coating apparatus used for manufacturing a general coated paper / paperboard. By applying a single-side coating amount of 5 to 15 g / m ^{2 on} both sides, the printability and design of the paper could be further improved. A roll coater, a gravure coater, a die coater, a curtain coater, a spray coater, a blade coater, a rod coater (bar coater), a notch bar coater, an air doctor coater or the like can be used for coating the coating composition on the paper. More preferably, a non-contact type die coater, curtain coater, spray coater, air doctor coater or the like is preferred.

  In particular, in the case of a non-contact type IC tag in which an antenna coil, a wiring pattern, an IC chip, etc. are still mounted on an insulating film that is not sealed with a sealant, and an IC tag with a built-in antenna, conditions for raw material stock Has found that the function of the non-contact type IC tag is impaired. In order to prevent functional failure of the IC tag during paper making and to prevent functional failure of the IC tag during long-term use of the paper in which the IC tag is inserted, a paint containing non-coated paper or pigment is applied. It is preferable that the cold water extraction pH prescribed | regulated by JISP8133: 1998 of the paper which does not cover, ie, a paper base material or a multilayer paper base, exceeds 6.2. Furthermore, the pH is 9 or less, more preferably 8 or less. When this pH exceeds 9, the fixing of the paper strength improver and the sizing agent to the pulp fiber is inhibited by the alkali filler and the chemical, and as a result, the development of strength and sizing degree is inhibited. In particular, when high sizing is required as in the present invention, the cold water extraction pH is 9 or less, more preferably 8 or less. Further, it is preferable that the total chlorine content of the non-coated paper or the paper not coated with the paint containing the pigment, that is, the paper base material or the multilayer paper base material is 400 ppm or less, preferably 200 ppm or less. Furthermore, the water-soluble chloride content defined by JIS P 8144: 1998 of the non-coated paper or the paper not coated with the paint containing the pigment, that is, the paper base material or the multilayer paper base material is preferably 80 ppm or less. Has found that it is necessary to have a paper blend satisfying 50 ppm or less.

  Next, a method for inserting the non-contact type IC tag into a fixed position in the paper layer will be described below. The non-contact type IC tag is affixed at a predetermined interval with the non-contact type IC tag itself as it is or on a thin tape obtained by slitting a sheet material such as a film such as PP, PE and PET or a nonwoven fabric. The tape on which the non-contact type IC tag is affixed is inserted into the paper mat through the non-contact type IC tag introduction tube through the non-contact type IC tag introduction tube using water or diluted paper as a carrier. As a wire type for inserting a non-contact IC tag at a fixed position in a paper layer, when it is inserted into a paper layer of a single-layer paper substrate, the inclined wire shown in FIG. In the case where the paper layer is inserted into at least one paper layer among the paper layers constituting the multilayer paper base material, a circular mesh wire shown in FIG. 6 (A) or (B) is used. A circular net type can also be used for a single-layer paper base.

  FIG. 5 shows an inclined wire. In the inclined wire, a pound 6 made of a paper material diluted to about 0.1 to 0.3% introduced from the inlet 4 is formed on the inclined region a of the wire 5. The slant-type wire stock mat is formed by dehydrating the pound 6 with a suction box 7 or a table roll (not shown) installed on the opposite side of the wire 6 through the wire, so that the wire a region of the diluted stock pond. The paper mat 8 is gradually formed on the wire 5 to finally become the paper mat 8 having a predetermined amount of the basis weight. The formed paper mat 8 is separated from the wire 5 and sent to the next pressing step.

  The non-contact type IC tag is inserted into the paper layer by the inclined wire shown in FIG. 5 in a non-contact manner with the non-contact type IC tag itself as it is or with the tape 10 with the non-contact type IC tag attached to the tape. In the middle of the formation of the paper mat through the mold IC tag introduction tube 9, the paper is cut into the paper layer. In order to surely insert the non-contact type IC tag into the center of the paper mat in the thickness direction of the paper mat 8, the tip of the non-contact type IC tag introduction tube 9 is installed in the second suction box 7 or many. It is preferable that the position of the table roll is 1/3 position from the inlet 4 side of a certain table roll (not shown).

  FIG. 6 shows a circular mesh wire. (A) is a forward flow type bat, (B) shows a reverse flow type bat. In order to produce a multilayer paper substrate composed of two or more layers, these bats are combined using the number of bats corresponding to the number of layers of the multilayer paper substrate.

  In the forward flow type bat (A), 0.1 to 0.3% of the diluted paper stock is introduced from the inlet 4 and flows in the same direction as the rotation direction of the circular wire 5, and the excess overflows from the overflow port 12. Go. In the middle of this, a paper mat is gradually formed on the circular mesh wire 5 by suction inside the circular mesh. The formed paper mat 8 is transferred to the blanket 11 and sent to the press part. The synthetic paper made from the forward flow type bat (A) has a good texture and has a uniform basis weight and thickness distribution in the width direction.

  On the other hand, the reverse flow type bat (B) is introduced from the inlet 4 in the direction opposite to the rotation of the circular mesh wire 5 in an amount corresponding to the basis weight of the 0.3 to 0.6% diluted paper stock. 8 shows that the diluted paper stock is introduced from the inlet 4 and flows backward in the direction of rotation of the circular mesh wire, and the total amount of the paper stock introduced while flowing forward and in the direction of rotation of the circular mesh wire is used as the paper mat 8. It is formed on the circular mesh wire 5. The formed paper mat 8 is transferred to the blanket 11 and sent to the press part. The backflow bat (B) is suitable for the manufacture of cardboard.

  The non-contact type IC tag is inserted into the paper layer by the circular mesh wires (A) to (B) in FIG. 6 by using the non-contact type IC tag itself as it is or by using the non-contact type IC tag as a tape. The attached tape 10 is inserted into the paper mat during the formation of the paper mat 8 through a non-contact type IC tag introduction tube (not shown). As a result of intensive studies, the tip of the non-contact type IC tag introduction tube is positioned at 5 o'clock in the case of the forward bat in FIG. It was found that it is preferable to set the position to a in the figure from 7 o'clock to 7 o'clock, and in the case of (B) the backflow bat, to the position b in the figure from 7 o'clock to 9 o'clock.

  The non-contact type IC tag inserted in the paper mat by the non-contact type IC tag introduction tube is a suction box or table roll suction in the case of inclined type wire, or the inside of the net wire in the case of circular type wire. The sheet was sucked into the predetermined position in the width direction and the flow direction of the paper machine easily and easily by the suction force associated with the formation of the paper mat due to the suction dehydration of the diluted paper.

  In order to efficiently manufacture non-contact type IC tag interleaved paper whose final application is card size (width 57mm x length 84mm), the width of the paper machine is taken into account when paper is shrinked due to drying and pulling. Although it is necessary to determine the spacing between the non-contact type IC tags in the direction and the flow direction, the non-contact type IC tags are densely printed at a minimum of 57 mm in the width direction of the paper machine and at a minimum of 84 mm in the flow direction. It is necessary to penetrate precisely into the layer. In particular, in the width direction of the wire, a large number of non-contact type IC tag introduction pipes must be densely arranged with a minimum spacing of 57 mm. At this time, the non-contact type IC tag introduction tube is extremely inferior because it blocks or disturbs the water flow of the diluted stock fed into the pound or bat, causing the paper to be thick and thin, causing streaks, etc. The problem of becoming. In addition, the paper was deposited on the non-contact type IC tag introduction tube, and the paper became dirty and became a cause of soiling. As a result of intensive studies, it was possible to solve the above-mentioned problem by reducing the number of non-contact type IC tag introduction tubes inserted per bat by inserting non-contact type IC tags into a plurality of layers. For example, by using two bats and inserting a non-contact type IC tag into two layers, the distance between the non-contact type IC tag introduction pipes becomes 114 mm at the minimum. Thus, by increasing the interval between the non-contact type IC tag introduction pipes, the non-contact type IC tag introduction pipes did not disturb the water flow of the diluted stock in the bat, and no wrinkles / stains were generated. By setting the interval between the non-contact type IC tag introduction pipes to an interval that does not destroy the formation of the paper and that does not generate dirt, and by interposing the non-contact type IC tag into a plurality of layers, It was possible to obtain a paper in which a non-contact type IC tag was inserted by continuously and efficiently dealing with a small-sized end use product.

  The thickness and cross-sectional shape of the non-contact type IC tag introduction tube are appropriately adjusted in accordance with the shape of the non-contact type IC tag to be inserted, so that the non-contact type IC tag is inserted at a certain position, and This is also preferable in order to suppress the occurrence of paper thickness and streaks.

Thereafter, the operation of the non-contact type IC tag inserted into the paper was measured using a model HE-MU380-MMP201 manufactured by Hitachi, Ltd. It was confirmed that the operation of the non-contact type IC tag inserted into the paper before processing was functioning normally. The function stop frequency of the non-contact type IC tag inserted before and after the paper processing was expressed in the same manner as in <Measurement of function of non-contact type IC tag inserted into the paper base>.

In this example and comparative example, the card (basis weight 270 g / m ² , dimension width 54 mm x length 85 mm), postcard (basis weight 190 g / m ² , dimension width 100 mm x length 147 mm) and information recording paper ( The basis weight was assumed to be 80 g / m ² , dimension width 210 mm × length 297 mm).

<Example 1>
Tables 9 to 11 examine the operational status of the function of the non-contact type IC tag inserted according to the pressurizing condition of the press machine installed in the paper machine and the quality of the paper in which the non-contact type IC tag is inserted. The results were shown.

In this study, as the wet part, three round net type (forward flow) bats were used as the wet part, and those arranged as shown in FIG. 6C were used. with stock a, total basis weight performs end-use in all basis weight 270 g / m ² of more basis weight 90 g / m ² × three layers assuming the card application, the narrowing plow non-contact type IC tag middle The second bat corresponding to this was punched into the paper layer by the method shown in FIG. The paper making speed was 5 m / min. Finally, the paper was coated on both sides under the conditions described in <Coating composition, coating apparatus and coating amount>. The non-contact type IC tag used for engraving and the engraving form were performed in the form 1 in which the IC tag X and IC tag X described in <Types of non-contact type IC tag and engraving form> were encased in the paper layer. . The IC tag X is a non-contact type IC tag that is not sealed with resin.

  The method of inserting the IC tag X into the paper layer with the second butt eye will be described in more detail. As a result of intensive studies, a non-contact IC tag introduction tube having an inner cross-sectional shape of 22 mm × 2 mm is used. The tip of a non-contact type IC tag introduction pipe (not shown) is installed at a position of a in the width direction of the wire at intervals of 184 mm, and the inlet 1 is installed at the same speed as the rotation speed of the wire. The IC tag X was continuously dropped into the introduction tube at intervals of 1.08 seconds while flowing the same diluted paper stock as was supplied into the vat from the inside of the paper layer. The clearance between the non-contact type IC tag introduction pipes was 161 mm.

As a comparison, the IC tag X was inserted between the paper layers. Using two bats (B) (I) and (II) in FIG. 6 (C), the IC tag X was manually and lightly attached to the surface of the wet paper that was rolled with the bat (II) and transferred to the blanket. Thereafter, the IC tag X was sandwiched between the layers with wet paper wound with a bat (I), and then sandwiched between the layers. The total basis weight was one layer basis weight of 135 g / m ² × two layers of 270 g / m ² .

  Paper stock blend A is a neutral papermaking stock using ECF bleached chemical pulp as raw pulp fiber, and the paper stock A and the paper used in general paper and paperboard described in <paper stock blend> Two types of paper stock A5 were examined in which the amount of sizing agent added to stock A was increased by about 5 times to further increase the degree of sizing.

  Further, the press conditions of the press machine of the paper machine are as shown in Tables 9 to 11, but the press conditions of the press part and the press conditions of the calendar are the conditions for manufacturing general paper and paperboard (100% ) To empty (0%). The pressure conditions of other pressurization equipment such as size press were not particularly changed. All of these linear pressures were 45 kgf / cm or less.

The continuous printed paper in which the IC tag X was inserted (uncoated paper) was wound on a reel without any process trouble. The winding was performed by coating the coating composition on both sides at 12 g / m ² (absolutely dry) on one side with a coating apparatus provided with an air doctor to obtain a coated paper. A continuous coated paper in which the IC tag X was inserted was obtained without any process trouble. About the non-coated paper and the coated paper obtained in this way, the degree of sizing of the non-coated paper, the paper texture / curl of the non-coated paper and the coated paper, white paper flatness, printing plane surface Evaluation was made on the property and RI strength (bulging). The results are as described in Table 9 to Table 11.

The results are as follows.
(1) The inserted IC tag X was accurately inserted in a paper layer at a predetermined location in parallel with the surface of the paper and aligned in the wire width direction.
(2) For example, as can be seen from the comparison between Example 1-1 and Comparative Example 1-2, the paper with the IC tag X is manufactured while maintaining the function of the IC tag X with a general paper / paperboard machine. For this purpose, the linear pressure of each pressurizing device must be 45 kgf / cm or less. In the embodiment, the pressurizing condition of each pressurizing device is 70% or less.
(3) Referring to Comparative Example 1-1, the IC tag X interleaving paper using the stock A used for the production of general paper / paperboard as it is is paper even under normal paper / paperboard pressurizing conditions. The habit / curl, white paper / printing surface flatness, and RI strength (swelling) are slightly reduced. The Steecht sizing degree was 350 seconds.
(4) Referring to Comparative Example 1-1 to Comparative Example 1-5, when the press part pressurization is lowered, the degree of sizing of the paper decreases, and the paper curl / curl, blank paper / printing flatness decreases. In particular, it is further deteriorated by the coating of the coating composition. This is thought to be due to the paper returning to the skin due to the water of the coating composition.
(5) Referring to Example 1-1 to Example 1-3, the linear pressure of the pressurizing condition of each pressurizing device was set to 0 kgf / cm by setting the paper sizing degree to 883 to 890 seconds. Even if it exceeds 45 kgf / cm, the quality level of general paper / paperboard can be ensured such as paper curl / curl, white paper / printing surface flatness and RI strength (swell). However, referring to Comparative Example 1-7 to Comparative Example 1-9, if the press part is empty even if the paper sizing degree is set to 883 to 889 seconds, the non-coated paper is curled or curled. The flatness of the white paper / printing surface and the RI strength (swelling) of the uncoated paper and the coated paper were poor. Therefore, pressurization at the press part is necessary.
(6) Referring to Comparative Example 1-10 and Comparative Example 1-11, paper in which the paper A5 was used and the IC tag X was interposed between the paper layers was also examined. The steecht size of the paper was 886-892 seconds. The paper had poor paper curl / curl, white paper / printed surface flatness and RI strength (swell). As for the flatness of the blank paper, the portion where the IC tag X was inserted was swollen. In addition, the printed surface showed a phenomenon that the ink was thin or did not ride around the swollen part (imperfection of the wall). Therefore, it was clarified from the comparison with the example that the paper in which the IC tag X was inserted in the paper layer was superior in paper texture / curl, white paper / printing surface flatness and RI strength (swell).
(7) As described above, the IC tag X interleaved paper that maintains the function of the IC tag X that has been incorporated using a general paper / paperboard machine and that has the same quality as that of ordinary paper / paperboard is the IC tag X In the paper layer, the pressurizing condition of each press machine of the paper machine is set to a linear pressure exceeding 0 kgf / cm to 45 kgf / cm or less, and the paper has a Steecht sizing degree of 883 seconds or more. I understood that it was obtained. In addition to this condition, the pressurizing condition of each pressurizing device of the paper machine is usually more than 0% to 70% or less, preferably 30% or more to 70% or less of the pressurizing condition at the time of manufacturing general paper / paperboard. good.

Tables 12 to 14 show the results of studying the influence on the function of the non-contact type IC tag due to the difference in the stock composition.

  The pressurizing conditions of the press machine of the paper machine are as described in Tables 12 to 14, but the linear pressure exceeded 0 kgf / cm and was 45 kgf / cm or less. Here, the pressure condition of the pressure device of the paper machine is 30% or more to 70% or less of the normal condition.

  Three types of non-contact type IC tags, IC tag X, IC tag Y, and IC tag Z described in <Types of non-contact type IC tag and insertion type> were examined. The IC tag X is an external antenna type IC tag not sealed with resin, the IC tag Y is an external antenna type IC tag sealed with resin, and the IC tag Z is an IC tag with a built-in antenna.

  As for the inner cross-sectional shape of the non-contact type IC tag introduction tube, the rectangular shape of 22 mm × 2 mm used in Example 1 was used for the IC tags X and Y, and the inner cross-section of the IC tag Z was determined as a result of intensive studies. A pipe having a diameter of 3 mm was used.

  Three types of paper stocks, paper stock A, paper stock B, and paper stock C described in <Paper stock formulation> were examined. Paper A is the paper used in Example 1, Paper B is a neutral papermaking material using chlorine bleached chemical pulp as the raw material pulp, and Paper C uses ECF bleached chemical pulp as the raw material pulp. Acid papermaking stock. The amount of the sizing agent added was increased to about 5 times the amount of <paper blending> so that the sizing degree of the paper was about 890 seconds.

  The coating composition was not applied to the paper in which the non-contact type IC tag was inserted.

The other conditions were the same as in Example 1. The papermaking speed was 5 m / min, the total basis weight was 270 g / m ² , and the basis weight was 90 g / m ^2. The type IC tag was automatically dropped at 1.08 second intervals. The operating state of the function of the non-contact type IC tag inserted was examined under the conditions that assumed immediately after the manufacture of the paper thus obtained and after a long time.

The results are as follows.
(1) All three types of non-contact type IC tags inserted were accurately inserted in a paper layer at a predetermined location in parallel with the surface of the paper and aligned in the wire width direction.
(2) It should be noted that the degree of sizing of the paper was 677 to 902 seconds. The paper texture and curl of the paper in which the non-contact type IC tag was inserted were all good.
(3) Referring to Example 2-1 to Example 2-4, the cold water extraction pH of the paper with stock formulation A is 6.4, the total chlorine content in the paper is 140 ppm, and the water solubility in the paper The chloride content was 42 ppm. Referring to Comparative Example 2-1 to Comparative Example 2-4, the stock formulation B is 6.2, 460 ppm and 90 ppm, respectively, and referring to Comparative Example 2-5 to Comparative Example 2-8, the stock C Were 5.0, 145 ppm and 45 ppm, respectively.
(4) Referring to Comparative Example 2-5 and Comparative Example 2-7, in Paper C (acidic papermaking paper), IC tags X and Z had already stopped functioning immediately after production.
(5) Referring to Comparative Example 2-1, Comparative Example 2-3, Comparative Example 2-4, and Comparative Example 2-8, under conditions assuming long-term use of the paper in which the non-contact type IC tag is inserted The operation status of the non-contact type IC tag inserted in the IC tag X and the IC tag Z stopped in the case of the paper fed using the paper material B and the paper material C. However, referring to Example 2-1 to Example 2-4, in the case of stock A, the function did not stop. In addition, referring to Comparative Example 2-2 and Comparative Example 2-6, the IC tag Y did not stop functioning in any of the paper stocks.
(6) It was found that the IC tags X and Z are not resistant to acidic substances such as sulfate radicals and chlorine.
(7) As a paper material for inserting a non-contact type IC tag, the cold water extraction pH of the paper exceeds 6.2, the pH is around 9 or less, and the total chlorine content in the paper is 400 ppm or less. It was found that the content of water-soluble chloride in the paper is preferably not more than 200 ppm and preferably not more than 80 ppm, preferably not more than 50 ppm.
