Abstract
The utility model provides a sealing adhesive tape of a double-adhesive structure, which comprises a basal body, wherein a first sticky region, a second sticky region with the stripping strength smaller than that of the first sticky region, and a non-sticky region, which are sequentially arranged on the upper surface of the basal body. Through the arrangement of the sticky regions with different stripping strengths, the sealing adhesive tape is easy to be torn from a packaging bag body which is adhered to the second sticky region and is always adhered to a sealing tongue which is adhered to the first sticky region.
Description
Technical field
The utility model relates to a kind of sealing tape, is meant the sealing tape of two plastic structures especially.
Background technology
Use for convenient, existing small package bag (as Packing bag for facial tissue or sanitary towel package etc.) mostly is provided with one in order to the easily openable mouth with content taking-up use, and at easily openable mouth place one sealing tape is set.For instance, commercially available Packing bag for facial tissue is generally the packing bag of nonrigid plastic rectangular parallelepiped, one side of rectangular parallelepiped packing bag is provided with one and comprises easily broken tooth trace and the easily openable mouth that seals tongue, and owing to often be placed with plurality of sheets of paper towel in the existing Packing bag for facial tissue, therefore, when in packing bag, also having the paper handkerchief residue, also need to use a sealing tape so that the easily openable mouth is sealed once more, existing sealing tape is mostly by a matrix, and be arranged at the hot melt adhesive layer of this matrix one side surface and do not glue district's composition, during use, the hot melt adhesive layer of sealing tape bond simultaneously the packing bag body and the envelope tongue, and the adhesive surface of hot melt adhesive layer and envelope tongue is greater than the adhesive surface of hot melt adhesive layer and packing bag body, make the cohesive force of hot melt adhesive layer and envelope tongue greater than the cohesive force of itself and packing bag body, by above-mentioned structure, make that sealing tape both had been easy to tear off from the packing bag body, and secure bond is being sealed on the tongue all the time.
Yet, in above-mentioned mode, what adopt with packing bag agglutinating hot melt adhesive layer with envelope tongue agglutinating hot melt adhesive layer is same kind, the hot melt adhesive of same thickness, therefore, it is identical with packing bag body or envelope tongue agglutinating unit cohesive strength, like this, when glue viscosity is too big, sealing tape will be difficult to tear off from the packing bag body, in case and the user is firmly excessive, then can cause packing bag body or envelope tongue breakage, otherwise, when glue viscosity was not enough, the user one firmly will make sealing tape break away from packing bag body and envelope tongue simultaneously slightly, is difficult to play the effect of sealing.
The utility model content
The utility model provides the sealing tape of two plastic structures, in order to solve the above-mentioned problems in the prior art.The utility model is by being provided with the sticky region that stripping strength does not wait, thereby makes that sealing tape both had been easy to tear off from packing bag body (with low stripping strength sticky region bonding), and all the time secure bond on envelope tongue (with high-peeling strength sticky region bonding).
The technical solution of the utility model is as follows:
The sealing tape of two plastic structures comprises a matrix, it is characterized in that: the upper surface of this matrix is disposed with first sticky region, its stripping strength less than the not sticking district of second sticky region and of the first sticky region stripping strength.
As further improvement of the utility model, this first sticky region and second sticky region are provided with continuously.
As further improvement of the utility model, between this first sticky region and second sticky region transcribed spacer is set.
As further improvement of the utility model, described first sticky region is first adhesive area that is provided with continuously, and described second sticky region is second adhesive area that is provided with continuously.
As further improvement of the utility model, described first sticky region is first adhesive area that is provided with at interval, and described second sticky region is second adhesive area that is provided with at interval.
As further improvement of the utility model, this first adhesive area grammes per square metre is identical with the second adhesive area grammes per square metre, stores so that sealing tape curled.In general this first adhesive area grammes per square metre can be at 15～32g/m
2Between select, similarly, this second adhesive area grammes per square metre also can be at 15～32g/m
2Between select.
As further improvement of the utility model, 180 ° of stripping strengths of this first adhesive area are 15～25N/in, and 180 ° of stripping strengths of this second adhesive area are 8～22N/in.
As further improvement of the utility model, the lower surface silicon-coating oil reservoir of this matrix.Like this, in process of production, a large amount of sealing tapes of producing directly can be curled stores, and need not to worry that viscose glue can be transferred on the lower surface of matrix.
As further improvement of the utility model, described matrix is used for nonwoven layer by one and a plastics leaching membrane layer is formed, this nonwoven layer is fixedlyed connected with this plastics leaching membrane layer, the lower surface of this nonwoven layer applies described silicon layer, and the upper surface of this plastics leaching membrane layer then is disposed with described first sticky region, second sticky region and described not sticking district.In above-mentioned structure, nonwoven layer provides the soft-surface of sealing tape, promote whole feel and class, the plastics leaching membrane layer then plays the effect that connects nonwoven layer and adhesive area, and can prevent that viscose glue from infiltrating into nonwoven layer, be arranged within the nonwoven layer because plastics drench film, do not influence the feel and the outward appearance of matrix.
As further improvement of the utility model, described matrix is a plastics film, and described plastics film can be PP film or PE film or PVC film etc.
As further improvement of the utility model, described matrix, first sticky region, second sticky region and the not sticking shape of distinguishing are not limit, and can adjust voluntarily according to the shape of packing bag, easily openable mouth.
By above-mentioned to description of the present utility model as can be known, compare with prior art, the utlity model has following characteristics: the utility model is by being provided with the sticky region that stripping strength does not wait, thereby make that sealing tape both had been easy to tear off from packing bag body (with second sticky region bonding), and secure bond is being sealed on the tongue (with first sticky region bonding) all the time.

Fig. 3 is the sectional view of the utility model embodiment 2.
Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
Embodiment 1
The sealing tape of two plastic structures, as shown in fig. 1, comprise a PE plastics film 1, the lower surface silicon-coating oil reservoir 2 of this PE plastics film 1, the upper surface of this PE plastics film 1 is followed successively by first adhesive area 31, transcribed spacer 32, second adhesive area 33 and not sticking district 34,180 ° of stripping strengths of this first adhesive area 31 are 15～25N/in, and 180 ° of stripping strengths of second adhesive area 33 are 8～22N/in.For ease of the storage of curling, the grammes per square metre of this first adhesive area 31 is identical with the grammes per square metre of second adhesive area 33.
