Description

The present invention relates to laminated card stock.

In recent years, there has been known a card mount in which a card such as a membership card or a health insurance card is detachably provided on a part of the card mount, and the other part is used as an invoice (Patent Document 1).

This card mount can be pulled out from the card mount by separating the part to be the card at the pseudo-adhesive part of the tack paper. In the quasi-bonded portion, the plastic film pulled out from the card mount together with the card is quasi-bonded to the plastic film remaining on the card mount together with the tack paper. This quasi-adhesion prevents a situation in which the part to be the card is peeled off from the card mount even when the card mount passes through the printing machine.

The plastic used for pseudo-adhesion is generally a combination of polyester film and polyethylene resin.

Preferred embodiments of the present invention will be described in detail below with reference to the drawings. It should be noted that the embodiments described below do not unduly limit the scope of the invention described in the claims. Moreover, not all the configurations described below are essential constituent elements of the present invention.

1. Card Board A card board 10 according to the present embodiment will be described in detail with reference to FIGS. 1 to 3. FIG. FIG. 1 is a schematic diagram of a longitudinal section of the card mount 10 according to this embodiment, FIG. 2 is a plan view of the card mount 10 according to this embodiment, and FIG. 3 is a bottom surface of the card mount 10 according to this embodiment. It is a diagram.

As shown in FIGS. 1 to 3, the card mount 10 includes a main body 11, a card base material 20 that can be separated from the main body 11, and a laminate that is fixed to the back surface 14 of the main body 11 so as to cover the card base material 20. a member 30; In FIG. 2, the laminated member 30 is indicated by a dashed line because it is on the back side of the card mount 10, and in FIG.

The main body 11 is in the form of a thin sheet and has an area larger than that of the card base material 20, which is determined according to the use of the card. The main body 11 may be, for example, continuous form paper that continues in the vertical direction in FIG. Both ends of the body 11 are formed with a number of perforations 18 for engagement with the printing press. Perforations 19 are formed in the vertical direction of the main body 11 in FIGS. 2 and 3, and a plurality of main bodies 11 are continuous in the vertical direction in FIGS. Each body 11 can be separated at perforations 19 .

On the surface 12 of the main body 11, an address printed portion such as an address, and a cut 16 defining the outer shape of the card substrate 20 are formed. The cut 16 extends from the surface 12 through the main body 11 , the adhesive layer 31 and the transparent resin film 32 of the laminated member 30 and reaches the pseudo-adhesive layer 34 .

A laminated member 30 is fixed to the back surface 14 of the main body 11 with an adhesive layer 31 . The adhesive layer 31 can be composed of an adhesive or an adhesive thinly applied on the transparent resin film 32 . Here, an adhesive loses stickiness by being hardened after sticking, and a pressure-sensitive adhesive maintains stickiness to some extent after sticking. Examples of adhesives include natural rubber-based, synthetic rubber-based, acrylic, vinyl acetate-based, cyanoacrylate-based, silicone-based, and urethane-based adhesives. Various types such as solvent-based, non-solvent-based, one-liquid, two-liquid and UV-curing types can be used. Also, various hot-melt adhesives such as styrene-based block copolymers and ethylene-vinyl acetate copolymers can be used as adhesives.

The laminated member 30 has an area smaller than that of the main body 11 and has an area capable of covering the entire card substrate 20 from the back surface 14 . The laminated member 30 extends around the card substrate 20 and is fixed to the card mount 10 . By fixing the laminating member 30 around the card base 20, at least the supporting paper 36 of the laminating member 30 remains fixed to the card base 10 when the card base 20 is removed from the card base 10.例文帳に追加becomes possible.

The material of the main body 11 is, for example, paper, plastic, or the like. As the paper, for example, cast coated paper, art paper, coated paper, high-quality paper, etc. can be used. As plastics, for example, various polymer films such as polypropylene, polyethylene, polyethylene terephthalate, polybutylene terephthalate, and vinyl chloride can be used.

The laminated member 30 includes a transparent resin film 32 that can be integrated with the card substrate 20 and separated from the card mount 10, and a support paper 36 that has a pseudo-adhesive layer 34 that pseudo-adheres to the transparent resin film 32. - 特許庁In this embodiment, a part of the transparent resin film 32 is integrated with the card substrate 20 and can be separated from the card mount 10. However, if the size of the resin film 32 is the same as or smaller than the card substrate 20, For example, the entire transparent resin film 32 may be separable from the card mount 10 .

The laminated member 30 is obtained by laminating a plurality of films or sheets, and a known method for processing a card mount such as an extrusion lamination method can be employed.

The transparent resin film 32 has an area extending to the periphery of the card substrate 20 . The area of the transparent resin film 32 may be the same as or smaller than that of the card substrate 20 . When the area of the transparent resin film 32 is the same as or smaller than that of the card substrate 20, the laminated member 30 is fixed to the main body 11 by a pseudo-adhesive layer 34 or a support paper 36 and an adhesive or adhesive. The transparent resin film 32 is a plant-derived resin. Environmental load can be reduced because the transparent resin film 32 is a plant-derived resin. A plant-derived resin will be described later.

The pseudo-adhesive layer 34 employs a resin that can be pseudo-adhered to the plant-derived resin of the transparent resin film 32 . For the pseudo-adhesive layer 34, for example, if the plant-derived resin is polyester, polyethylene or polypropylene can be used. Also, the pseudo-adhesive layer 34 may be a plant-derived resin. Since the pseudo-adhesive layer 34 is made of a plant-derived resin, the environmental load of the card mount 10 can be further reduced.

The support paper 36 has the same size as the transparent resin film 32 and the pseudo-adhesive layer 34 . Support paper 36 may have a larger area than pseudo-adhesive layer 34 . The material of the support paper 36 is paper, plastic, or the like, for example. High-quality paper is used as the support paper 36 in this embodiment. The pseudo-adhesive layer 34 may be formed by extruding molten resin onto the support paper 36 with an extruder. When the support paper 36 is made of plastics, it may be molded by applying a pressure-sensitive adhesive or an adhesive and then extruding a molten resin.

As for the material, the number of laminated layers, the laminated structure, etc., of the laminated member 30, except for the transparent resin film 32, a known card mount laminated member 30 using pseudo-adhesion can be adopted.

1.1 Plant-Derived Resin The plant-derived resin that constitutes the transparent resin film 32 is a polymeric material that contains a plant-derived substance as a raw material and is obtained by chemically or biologically synthesizing it. The "plant-derived resin" used in the present application contains at least 25% by mass or more of plant-derived substances, and preferably contains 100% by mass of plant-derived substances. The "plant-derived resin" may be a biodegradable plastic that is eventually decomposed into water and carbon dioxide by the action of naturally occurring microorganisms after use. The plant-derived resin is preferably a polyester resin, such as polylactic acid, polyhydroxyalkanoate (PHA), polybutylene succinate (PBS), polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT). , polyurethane. The plant-derived resin can be, for example, polylactic acid. Polylactic acid is readily available on the market, and film products using polylactic acid are particularly preferred because they contain a high proportion of plant-derived substances.

By adopting a plant-derived resin as the transparent resin film 32, it is possible to reduce the environmental load on the card mount 10. FIG. By using renewable plants as raw materials, it is possible to contribute to the realization of a sustainable recycling-oriented society, and because plants are used as raw materials, it is possible to contribute to the reduction of carbon dioxide, which is a cause of global warming. can.

Polylactic acid is a polyester-based polymer in which lactic acid is polymerized through an ester bond to form a long chain. Polylactic acid is a biomass polymer that can be synthesized from plant-derived raw materials. As a raw material, it can be obtained by reacting starch obtained from potatoes, corn, etc. with an enzyme (such as amylase). As the polylactic acid, for example, a commercially available stretched film of "Ecologge (registered trademark of Mitsubishi Chemical Corporation)" can be used.

When the material of the transparent resin film 32 is polylactic acid, the material of the pseudo-adhesive layer 34 can be polyethylene or polypropylene.

However, if the transparent resin film 32 is a plant-derived resin, the peel strength with the pseudo-adhesive layer 34 tends to be low (for example, if polylactic acid is used, the peel strength is less than 4 N/m). Therefore, when the card mount 10 is conveyed through the printing machine, the pseudo-adhesive force of polylactic acid is weak, and there is a risk that the card substrate 20 or the laminate processing member 30 may be peeled off from the main body 11 .

1.2 Matting In order to increase the peel strength between the transparent resin film 32 and the pseudo-adhesive layer 34, the adhesive surface 321 of the transparent resin film 32 facing the pseudo-adhesive layer 34 is matted. By matting the adhesive surface 321, the surface area of the adhesive surface 321 is increased, and as a result, the peel strength with the pseudo adhesive layer 34 is increased. The peel strength between the transparent resin film 32 and the pseudo-adhesive layer 34 is 4 N/m or more in the 180-degree peel adhesive strength measurement method (with a peel speed of 500 mm/min) in 10 of JIS Z 0237. Preferably, it can be, for example, 4 N/m to 16 N/m or less.

By matting the adhesive surface 321, the peel strength against the pseudo adhesive layer 34 can be adjusted. Further, by subjecting the adhesive surface 321 to a matte finish, it is possible to improve the writability of the adhesive surface 321 with a writing instrument such as a ballpoint pen.

It is desirable that the transparency of the transparent resin film 32 that has been subjected to matte processing is such that the printing on the back surface 14 of the card substrate 20 can be read.

In matte processing, ink containing filler (for example, UV varnish) is applied to the transparent resin film 32.
can be printed on Specifically, the surface treatment is performed by printing (or applying) a matting ink or paint to which particles such as silica are added as a filler on the bonding surface 321 . By forming fine irregularities with a filler on the adhesive surface 321 by matting, the surface area of the film can be increased, the peel strength can be adjusted, and an improvement in writability can be expected.

Matting may be performed by sandblasting the adhesive surface 321 . Specifically, the surface treatment is performed by blowing abrasive particles against the bonding surface 321 with an air force. By forming fine unevenness on the adhesive surface 321 by sandblasting, the surface area of the film can be increased, the peel strength can be adjusted, and an improvement in writability can be expected.

2. Card The card 40 will be described with reference to FIG. FIG. 4 is a schematic diagram showing a state in which the card 40 is extracted from the card mount 10 according to this embodiment.

FIG. 4 shows a state in which the card 40 is pulled out from the card mount 10 of FIG. When the card mount 10 is bent and the card substrate 20 is lifted from the cut 16 with a finger, the interface between the transparent resin film 32 and the pseudo-adhesive layer 34 is peeled off, and the card 40 can be pulled out. The card 40 pulled out from the card mount 10 has a mat portion 32 a which is part of the transparent resin film 32 separated from the card mount 10 integrally with the card base material 20 on the bottom surface. The laminated member 30 of the card mount 10 is left on the card mount 10 with the remaining portion 32b of the transparent resin film 32 interposed therebetween.

The bottom surface of the card 40 is covered with a transparent resin film 32. - 特許庁The transparent resin film 32 protects the print or pattern printed on the card base material 20 from abrasion and moisture, thereby improving the environmental durability of the card 40 . Further, the card 40 may have a writability by leaving a mat portion 32a subjected to mat processing on the adhesive surface 321 of the card 40 . Being writable, the card 40 can be used, for example, to write the user's name on a health insurance card.
