Description

  The present invention relates to a photographic film packaging body in which a photographic film containing a patrone containing a film tongue end portion and housed in a photographic film cartridge is wrapped with a thermoplastic resin film packaging material, and a photographic film packaging housing for housing a photographic film packaging body. The present invention relates to a box (hereinafter simply referred to as a storage box), a photographic film assembly package (hereinafter also simply referred to as an assembly package) in which a photographic film package is stored in a storage box for a photographic film package, and a photographic film package manufacturing method.

  At present, the packaging form of light-shielded photographic film sold in the market is a form that is put in an outer box with an identification design after light-shielding packaging and moisture-proof sealed packaging to maintain performance. ing. For example, in the case of a 135 mm size film, the film tongue end is stored in a container such as a resin cartridge or a metal cartridge that is standardized by the ISO standard while being wound around a shaft (light-shielding packaging) These are put in a moisture-proof resin container (also called a resin can) (moisture-proof packaging), and further put in an outer box printed with an identification design.

  In the case of advanced photo film as well as in the case of 135 mm size film, it is wound around a shaft and stored in a light-shielding resin cartridge, then placed in a moisture-proof resin container, or has an aluminum layer. After being sealed and packaged with a moisture-proof material, it is put in an outer box printed with an identification design.

As a problem of these packaging forms, all are over-packed, and when considering environmental problems, it cannot be said to be a preferable packaging form. As a countermeasure against these excessive packaging forms, for example, a photographic photosensitive material package in which a photographic photosensitive material that is light-shielded and packaged is wrapped with a transparent moisture-proof material having a moisture permeability of 1.0 g / m ² · 24 h (40 ° C. and 90% RH) or less; An integrated package body in which a plurality of the photosensitive material package bodies are collected and stored in a box is known (for example, see Patent Document 1). The light-sensitive packaged photographic photosensitive material is a transparent moisture-proof material having a moisture permeability of 1.0 g / m ² · 24 h (40 ° C./90% RH) or less and at least one selected from a desiccant, a deodorant, an antioxidant, and a radical scavenger. A photographic film package in which two photographic film stabilizers coexist is known (for example, see Patent Document 2).

  The technology disclosed in Patent Literature 1 and Patent Literature 2 is surely effective in reducing the amount of waste packaging material because there is no longer any plastic container or paper box that has been subjected to design printing. Have the disadvantages.

1) Conventionally, photographic film may deteriorate in performance when left in a high humidity environment for a long time. Therefore, packaging with a moisture permeability of 1.0 g / m ² · 24h (40 ° C · 90% RH) or less Material is used. In order to obtain this moisture permeability, the cost is high because a multilayer material using an Al foil and an inorganic vapor deposition film is used. Moreover, since recent photographic films are resistant to high humidity environments, packaging materials having such moisture permeability are not necessary.

  2) When the integrated packaging body described in Patent Document 1 is dropped during handling during transportation, there is a risk that the photographic film packaging body accommodated by the impact receives pressure and causes a performance abnormality.

  3) The photographic film package (hereinafter also simply referred to as a package) described in Patent Document 2 must be selected because it may adversely affect the performance of the photographic film depending on the type of photographic film stabilizer used. It must be troublesome. Further, since a means for preventing spillage at the time of coexistence is required, excess material is discharged at the time of disposal.

  4) Since the film tongue end protruding from the patrone for photographic film (hereinafter also simply referred to as “patrone”) is wrapped around the body of the cartridge and stored, the film tongue end has a curl and is a hindrance to loading. Become.

  5) When storing a photographic film containing a patrone that has a film tongue end in a bag made of a thermoplastic resin film packaging material (hereinafter also referred to simply as a packaging material) by hand, the film tongue end is the entrance of the bag. Production efficiency does not increase because it is difficult to store.

Under such circumstances, development of a package that can solve the above problems, a method for manufacturing the package, and a safe storage box and collective package for transporting the package is desired.

Next, the packaging material according to the present invention will be described. The packaging material according to the present invention preferably has a moisture permeability of 1.0 to 20 g / m ² · 24 h (40 ° C. · 90% RH). The thickness is 30 to 400 μm, preferably 40 to 200 μm, more preferably 60 to 100 μm. By producing a package using a packaging material having such a moisture permeability, the humidity inside the package can be maintained at 50 to 95% RH, and the environment in which the package is used is low. It has become possible to take a wide range from humidity to high humidity.

If the moisture permeability is less than 1.0 g / m ² · 24h (40 ° C · 90% RH), an inorganic vapor-deposited film such as aluminum foil, Al ₂ O ₃ , or SiO _x will be used. The cost may increase depending on the resin film. When it exceeds 20 g / m ² · 24 h (40 ° C. · 90% RH), depending on the type of photographic film, the performance may be deteriorated by storage. The moisture permeability is a value measured according to JIS Z 0208-1976.

  When the thickness is less than 30 μm, the moisture permeability becomes high, and depending on the type of the photographic film, the performance may be deteriorated by storage. If it exceeds 400 μm, it becomes too thick and the packaging suitability may be deteriorated depending on the type of packaging material.

The packaging material according to the present invention can be used without particular limitation as long as it has a moisture permeability of 1.0 to 20 g / m ² · 24 h (40 ° C. · 90% RH). (For example, new development of functional packaging materials. Thermoplastic resin film described by Toray Research Center, Inc.).

  Polymer film used as a general packaging material as a thermoplastic resin film used as a base material for packaging materials (for example, thermoplastic resin film described in Toray Research Center, Inc., a new development of functional packaging materials) Ethylene tetrafluoro Ethyl copolymer (ETFE), high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene, biaxially oriented polypropylene (0PP), polystyrene (PS), polymethyl Methacrylate (PMMA), biaxially stretched nylon 6, polyethylene terephthalate (PET), polycarbonate (PC), polyimide, polyether styrene (PES), unstretched polypropylene (CPP), stretched nylon (ONy), polyester (PET), se Han, polyvinyl alcohol (PVA), the stretching vinylon (OV), ethylene - vinyl acetate copolymer (EVOH), vinylidene chloride (PVDC) and the like can be used.

  In addition, these thermoplastic resin films may be used alone or as a laminate of two or more films as required. For example, CPP / OPP, PET / OPP / LDPE, Ny / OPP / LDPE, CPP / OPP / EVOH, Saran UB / LLDPE A biaxially stretched film is used as a raw material.) K-OP / PP, K-PET / LLDPE, K-Ny / EVA (where K is a film coated with vinylidene chloride resin) and the like are used. . Of course, a multilayer film made by coextrusion with a different kind of film, a multilayer film made by laminating at different stretching angles, and the like can be used. Further, it is naturally possible to combine the density and molecular weight distribution of the film used to obtain the required physical properties of the packaging material.

  When laminated, the innermost thermoplastic film is low density polyethylene (LDPE), linear low density polyethylene (LLDPE), low density polyethylene (LDPE) produced using a metallocene catalyst, linear low density. Polyethylene (LLDPE), and films using a mixture of these films and high-density polyethylene (HDPE) films are used.

  As the method for producing the laminated film, various generally known methods are used. For example, the laminated film is produced using a wet lamination method, a dry lamination method, a hot melt lamination method, an extrusion lamination method, or a thermal lamination method. Is possible. In addition, depending on the material used, it can be made by a multilayer inflation system.

  As the adhesive used when laminating, generally known adhesives can be used. For example, polyethylene thermoplastic resins such as various polyethylene resins, various polypropylene resins, hot melt adhesives, ethylene-propylene copolymer resins, ethylene-vinyl acetate copolymer resins, ethylene-ethyl acrylate copolymer resins, etc. There are thermoplastic resin hot-melt adhesives such as coalescence resins, ethylene-acrylic acid copolymer resins, ionomer resins, and other hot-melt rubber adhesives. Typical examples of emulsion-type adhesives that are emulsion and latex adhesives are polyvinyl acetate resin, vinyl acetate-ethylene copolymer resin, vinyl acetate and acrylate copolymer resin, vinyl acetate and maleate ester. There are emulsions such as copolymer resins, acrylic acid copolymers, and ethylene-acrylic acid copolymers. Typical examples of latex adhesives include rubber latexes such as natural rubber, styrene butadiene rubber (SBR), acrylonitrile butadiene rubber (NBR), and chloroprene rubber (CR). Dry laminate adhesives include isocyanate adhesives, urethane adhesives, polyester adhesives, and others, as well as paraffin wax, microcrystalline wax, ethylene-vinyl acetate copolymer resin, and ethylene-ethyl acrylate. Known adhesives such as hot melt laminate adhesives, pressure sensitive adhesives, heat sensitive adhesives and the like blended with polymer resins can also be used. More specifically, polyolefin resin adhesives for extrusion laminating include polymers and ethylene copolymer (EVA, EEA, etc.) resins made of polyolefin resins such as various polyethylene resins, polypropylene resins, polybutylene resins, Ionomer resin (ionic copolymer resin) such as L-LDPE resin copolymerized with ethylene and other monomers (α-olefin), DuPont Surlyn, Mitsui Polychemical Co., Ltd., and Mitsui Petrochemical Admer (adhesive polymer), etc. Other UV curable adhesives have recently begun to be used. In particular, LDPE resin and L-LDPE resin are preferable because they are inexpensive and have excellent laminating properties. A mixed resin in which two or more of the above-described resins are blended to cover the defects of each resin is particularly preferable. For example, when L-LDPE resin and LDPE resin are blended, spreadability is improved and neck-in is reduced, so that the lamination speed is improved and pinholes are reduced. When adhering each layer using the adhesive, it is preferable to laminate the layers so that the adhesive strength is 350 g / 15 mm width or less.

  The packaging material according to the present invention preferably has a static friction coefficient μ1 on the outer surface side that is 10 to 100% higher than a static friction coefficient μ2 on the inner surface side. By using a packaging material in which the static coefficient of friction between the outer surface and the inner surface is in such a relationship for the production of the package, handling of the bag produced using the packaging material and patrone-containing photographic film when manufacturing the package Can be easily inserted into the bag. The static friction coefficient is a value measured according to JIS K7125 1999.

  When the static friction coefficient μ1 on the outer surface side is less than 10% with respect to the static friction coefficient μ2 on the inner surface side, depending on the number of photographic films containing the patrone to be put in the bag for producing the package, the bag may be slippery due to the mass and difficult to work. There is a case. When it exceeds 100%, it is difficult for the package to slip, and handling may be difficult depending on the sales method at the store.

  As a method for increasing the static friction coefficient μ1 on the outer surface side by 10 to 100% higher than the static friction coefficient μ2 on the inner surface side, the surface may be matted by calendering after film formation. Further, it can be adjusted by adding a matting agent and a lubricant. As the matting agent, a matting agent which is fine particles of an organic or inorganic compound can be added. Examples of organic compounds include water dispersible vinyl polymers (for example, polymethyl acrylate, polymethyl methacrylate, polyacrylonitrile, acrylonitrile-α-methylstyrene copolymer, polystyrene, styrene-divinylbenzene copolymer, polyvinyl acetate, Polyethylene carbonate, polytetrafluoroethylene, etc.), cellulose derivatives (eg, methylcellulose, cellulose acetate, cellulose acetate propionate, etc.), starch derivatives (eg, carboxy starch, carboxynitrophenyl starch, urea-formaldehyde-starch reactant, etc.) Examples thereof include gelatin hardened with a hardener and hardened gelatin obtained by coacervate hardening to form fine capsule hollow particles.

  Examples of the inorganic compound include silicon dioxide, titanium dioxide, magnesium dioxide, aluminum oxide, barium sulfate, calcium carbonate, silver chloride desensitized by a known method, silver bromide, glass, diatomaceous earth, and the like.

  The above matting agents can be used by mixing different kinds of substances as required. The size and shape of the matting agent are not particularly limited, but those having a particle size of 0.1 to 30 μm are preferably used. The particle size of the matting agent can be measured with a scanning electron microscope.

  Various known lubricants can be used as the lubricant. Examples include silicones, oleic amides, erucic amides, stearic amides, bis-fatty acid amides, alkylamines, hydrocarbons, fatty acids, esters, metal soaps, etc. Various lubricants are commercially available. The addition amount of this lubricant is preferably 0.03 to 2% by mass. The matting agent and the lubricant can be added to the thermoplastic resin film by the same method as the above-mentioned pigment addition method.

  The thermoplastic resin film used for the packaging material having a static friction coefficient according to the present invention can be the same thermoplastic resin film as the packaging material having moisture permeability according to the present invention.

  The packaging material according to the present invention is preferably an air cap material having a burst strength of 100 to 6000 N / piece. When the burst strength is less than 100 N, depending on the type of cartridge, the photographic film containing the cartridge may not be sufficiently protected. When it exceeds 6000 N, depending on the type of the thermoplastic resin film constituting the air cap material, the air cap must be enlarged, and the packaging suitability may be deteriorated. By using a packaging material with such bursting strength for the production of the package, it becomes possible to protect the photographic film containing the patrone from external pressure. For example, a drop at the time of sale (dropping of the package, dropping of foreign matter) It is possible to protect the photographic film containing the patrone and sell it without any special handling.

  The air cap material according to the present invention preferably has an air particle size of 2 to 5 mm, an air particle height of 1 to 3 mm, and an air particle density of 50 to 80%. The air particle density indicates the area of the bottom surface of the air particles occupying the unit area.

  When the air particle size is less than 2 mm, depending on the type of the thermoplastic resin film constituting the air cap material, it may be difficult to maintain the burst strength according to the present invention, and the protection of the photographic film containing the cartridge will be insufficient. There is. When the air particle size exceeds 5 mm, the density of the required air cap cannot be obtained depending on the type of the thermoplastic resin film constituting the air cap material, and it is difficult to maintain the burst strength according to the present invention. Therefore, there are cases where the protection of the photographic film containing the cartridge is not sufficient.

  When the air particle height is less than 1 mm, depending on the type of the thermoplastic resin film constituting the air cap material, it becomes difficult to maintain the burst strength according to the present invention, and the protection of the photographic film containing the cartridge becomes insufficient. There is a case. If it exceeds 3 mm, the bulky storage box becomes large when producing a package, and the transport efficiency may be reduced.

  When the air particle density is less than 50%, depending on the type of the thermoplastic resin film constituting the air cap material, it is difficult to maintain the bursting strength according to the present invention, and the photographic film containing the cartridge is sufficiently protected. It may disappear. When it exceeds 80%, depending on the type of the thermoplastic resin film constituting the air cap material, flexibility may be lost and packaging suitability may be lost.

  The same thermoplastic resin film as that of the packaging material having moisture permeability according to the present invention can be used as the thermoplastic resin film used for producing the air cap material having burst strength according to the present invention. The thickness of the thermoplastic resin film is preferably 30 to 400 μm.

  Various additives can be added to the thermoplastic resin film used in the packaging material according to the present invention as necessary. For example, as an antistatic agent, cation activating agents such as quaternary ammonium salts, quaternary ammonium salt polymers, fatty acid amide derivatives and polyamine derivatives as described in JP-A-62-286042, and anions such as alkyl phosphates are used. Activators, glyceroborate alkylates, polyethylene glycol sorbitan fatty acid esters, alkylamine derivatives, glycerin fatty acid esters, sorbitan fatty acid esters and other nonionic surfactants, betaine-type amphoteric surfactants, imidazoline-type amphoteric surfactants and other double-sided surfactants Etc. Particularly preferred is an electrolysis stripper TS (trade name) manufactured by Kao Soap Co., Ltd., which has both functions of a lubricant and an antistatic agent. The addition amount of these antistatic agents is preferably 0.05 to 0.5% by mass.

  It is preferable to add an antioxidant in order to prevent the occurrence of spots and fish eyes and to prevent coloring failure. Known antioxidants can also be used. Examples include phenolic, ketoneamine condensation, allylamine, imidazole, phosphite, thiourea, sulfur, phosphorus, thioether, and metal deactivators.

  The method of adding the pigment and various light-shielding substances to the thermoplastic resin film can be performed by a generally known method, for example, the method described in pages 324 to 338 of the Japan Society for Polymer Processing Technology edited by Polymer Society. is there.

The preferred physical properties and layer structure of the packaging material according to the present invention used in the package shown in FIGS. 1 to 4 are as follows: 1) Moisture permeability is 1.0 to 20 g / m ² · 24 h (40 ° C./90% RH) 2) The static friction coefficient μ1 on the outer surface side is 10 to 100% higher than the static friction coefficient μ2 on the inner surface side, and 3) The air cap material has a burst strength of 100 to 6000 N / piece. Can be mentioned. The packaging material having these physical characteristics and layer structure may be used alone or in combination with physical characteristics.

  Using these packaging materials, the following effects can be obtained by producing the package shown in FIGS. 1) The humidity inside the package can be maintained at 50 to 95% RH, so that the photographic film can be used without any trouble due to condensation. 2) Production of the package is facilitated. 3) It is possible to protect the photographic film with patrone from external pressure, and it is possible to protect the photographic film with patrone from the accident at the time of sale (dropping of the package, falling of foreign matter on the package). It becomes possible to sell without handling. 4) Since the curling end of the film is difficult to curl, it is easy to load the photographic film containing the cartridge into the camera.

  FIG. 5 is a schematic exploded perspective view of a storage box used for producing a collective package.

  In the figure, 3 indicates a storage box. The storage box 3 includes a main body 301 having a storage portion 301b for storing the package 1 (see FIG. 1) and a lid 301a, and a partition frame 302 for storing the photographic film package in the storage portion 301b. The reinforcing member 303 is inserted between the inner peripheral surface of the storage portion 301 b and the end surface of the partition frame 302. The height of the reinforcing member 303 needs to be the same as the height of the main body and the length of the inner surface. The partition frame 302 has at least two partition members 302a and 302b that are orthogonal to each other. By inserting the partition frame 302 into the storage portion 301b, a partition for storing the package by the inner peripheral surface of the storage portion 301b. It comes to form.

  The vertical compressive strength of the reinforcing member 303 is preferably 50 to 1000N. If it is less than 50 N, the strength may be insufficient depending on the number of packaging bodies to be stored, and it may be difficult to sufficiently protect the packaging bodies. When it exceeds 1000 N, it becomes thick depending on the type of the reinforcing member, the volume of the storage box is reduced, the number of stored packages is reduced, and the transport efficiency may be deteriorated. The vertical compressive strength is a value measured according to the method B described in JIS Z 403-2: 1999.

  The thickness is preferably 0.5 to 2.5 mm. If it is less than 0.5 mm, the required compressive strength may not be obtained depending on the material used. If it exceeds 2.5 mm, the storage box becomes larger than necessary, and wasteful materials are used, and the cost may increase depending on the type of material.

  By arranging and storing the packaging bodies using the partition frame 302 shown in this figure, the packaging bodies are stored in an independent state, so that they can come into contact with an adjacent packaging body even in an accident such as dropping during transportation. Since there is no load, no load is applied and there is no failure such as crushing. Further, by using the reinforcing member 303, resistance against external pressure is enhanced, and resistance to the external pressure of the package housed in the compartment formed by the inner peripheral surface of the storage portion 301b and the partition frame 302 is improved, which is safer. It became a storage box.

  The form of the storage box of the present invention is not particularly limited. For example, various forms described in the latest paper processing manual Tech Times pages 825 to 831 can be used. The material used for the main body of the storage box of the present invention is not particularly limited, and may be resin, cardboard or paperboard, but cardboard is preferred from the viewpoint of cost, handling and strength. The cardboard to be used is not particularly limited and can be selected depending on the size of the storage box, and double-sided cardboard and double-sided cardboard are preferred. Also, the flute to be used can be appropriately selected from A flute, B flute, C flute, E flute, F flute and G flute.

  The material used for the partition frame may be the same as the material used for the main body of the storage box, and can be appropriately selected from materials that can be used for the main body. The material used for the reinforcing member is not particularly limited as long as it has the required vertical compressive strength. However, it is preferable that the material used for the main body of the storage box is the same as disposal after use. In addition, a resin material is preferable in view of recovery and reuse. Examples of the resin material include foam material and plastic cardboard.

  The number of photographic film packages to be stored in the storage box is not particularly limited, but 5 to 50 is preferable from the viewpoint of handling. Of course, you can put 100 in one box. Although the case of one stage is shown in this figure, a flat plate may be mounted on the partition plate to form a plurality of stages.

The seal portion 101a31 has an unsealed portion 101e on the opening 101d side. The width of the unsealed portion 101e is 90 to 95% with respect to the width when the opening 101d is sealed. Other reference numerals are the same as those in FIG.

  In Step 1, a photographic film containing a patrone is stored in a patrone that is 2-4 cm long from the opening of the pillow bag 101c. At this time, since the center on the opening side is not sealed, the opening can be opened largely, and since the film tongue end is short, the film tongue end is the pillow bag 101c having the opening. It can be easily stored without being caught on the edge of the.

  In Step 2, after the cartridge-containing photographic film is stored, the opening and the center on the opening side are sealed. Thus, the package 1 stored in the center seal type pillow bag shown in FIG.

In the figure, 101f shows the thermoplastic resin film sheet in a state where one side of the thermoplastic resin film sheet is folded and sealed, and two sides are not sealed. Other reference numerals are the same as those in FIG.

  In S1, the photographic film containing the cartridge is stored between the thermoplastic resin film sheet 101f with a film tongue end portion of 2 to 4 cm and stored in the cartridge. At this time, since the thermoplastic resin film sheet is not in a bag shape, it can be opened widely, and since the film tongue end portion is short, the film tongue end portion is not caught on the edge of the thermoplastic resin film sheet. It can be easily stored.

  In S2, it is set as a bag shape by sealing the long side of the thermoplastic resin film sheet 101f. In addition, it does not matter as a bag shape by sealing the short side of the thermoplastic resin film sheet 101f.

  In S3, the thermoplastic resin film sheet 101f is left and the end of the short side which is in an open state is sealed, and the package is stored in the pillow bag of the three-side seal type shown in FIG. 1 is produced. In addition, when the short side of the thermoplastic resin film sheet 101f is sealed in S2, the end of the super-side that is in an open state is sealed, so that the three-side sealing method shown in FIG. A package 1 stored in a pillow bag is produced.

  The present invention shown in FIGS. 1 to 7 has the following effects.

  1) Without using a resin container as in the past, packaging the patrone with a packaging material with a simple structure considering light transmittance and moisture permeability prevents condensation inside the package. Even if the photographic film is stored under high temperature and high humidity conditions, the performance of the photographic film can be maintained and it can be used with confidence.

  2) Since the curling of the film tongue end is not attached, handling of the film tongue end becomes easy when the cartridge is loaded into the camera.
