As the material of the upper sheet 2 and the lower sheet, a plastic material having good thermoplasticity and adhesiveness is used. Specifically, the sheet material is polyethylene (PE, polyetylene), PVC (Polyvinyl chloride), thermoplastic urethane (TPU, Thermoplastic Urethane), thermoplastic styrene (TPS, Thermoplastic styrene), polypropylene (PP, Polypropylene), polyurethane (PU, Polyurethane) is used. Preferably, PE, PVC, and PP are good in flexibility, heat adhesiveness and low cost. The thickness of the upper sheet 2 is 0.1 ~ 01mm, preferably 0.3mm sheet is used. The lower sheet 3 has a thickness of 0.3 to 2 mm, preferably 0.5 mm sheet. Since the top sheet and the bottom sheet are made of a flexible plastic material, the slab arrangement can be folded or rolled up, in which case the slab arrangement is easily handled.

As a method of adhering the upper sheet and the lower sheet, welding by high frequency heating and bonding with an adhesive are generally used. Bonding by the adhesive is applied by applying an adhesive to the adhesive surface in a state where the sheet is heated and softened, and bonding the upper and lower sheets by pressure welding. The application method of an adhesive agent is application | coating of the adhesive agent to an adhesive application roll, or application | coating by the spray method. Considering the process of heating and bonding the upper sheet and the lower sheet in the present invention, the present invention is good to use a laminating sheet provided with an adhesive layer so that the adhesive surface of the upper and lower sheets can be melted and attached to each other when heated and pressed. In this case, the slab arrangement can be produced more simply.

Laminating sheets are widely used in stationery and synthetic resin film formation. The conventional laminating sheet is generally comprised from the base material sheet and the adhesive material layer provided to the base material sheet. PE, PVC, PP, etc. are used as the base sheet, and the adhesive material applied to the base sheet is APP, EVA, EEA, EMA, vinyl chloride polymer copolymerized with a polar substance, chlorinated PP, chlorinated PE 20-100% of one or more of the mixtures, and one of the rotache, PIB, hydrogenated polyterpenes, cycloaliphatic hydrocarbon resins, terpene oil copolymers, terpene-phenol copolymers or alpha methylstyrene-vinyltoluene copolymers 1 to 70% of the mixture is dissolved in a solvent such as toluene, MEK, EA, acetone, alcohols, benzene, xylene, and the like, and is prepared by coating and drying a coating agent. The adhesive material thus prepared is applied to one surface of the base material and volatilized therein to form a dry hot-melt adhesive layer on the base material. When the adhesive layer is formed by overlapping the sheet with heat and pressure, the adhesive layers melt together. Contact surfaces of two sheets are attached. The hot-melt adhesive layer is formed by coating the coating liquid with an adhesive polymer, a tackifier, a wax, and the like, and then applying it to one surface of the base film and drying it. As the adhesive polymer, 20-100% of one or more mixtures of APP, EVA, EEA, EMA, a vinyl chloride polymer copolymerized with a polar material, chlorinated PP, and chlorinated PE are used. In addition, 1 to 70% of a mixture of at least one of rosin, PIB, hydrogenated polyterpene, cycloaliphatic hydrocarbon resin, terpene oil copolymer, terpene-phenol copolymer, or alpha methylstyrene-vinyltoluene copolymer was used as the tweak fire. . The adhesive may be thermally bonded by mixing the adhesive polymer and the tweak fire, but blocking may occur. To prevent this blocking, add wax, slip agent, antistatic agent, silicone oil, etc., usually use a lot of wax. As the wax, polypropylene wax, polyethylene wax, paraffin wax, polypropylene and polyethylene wax grafted with maleic hydride are used. Tackie fires and waxes in the coating liquid composition include toluene, toluene and toluene and methyl-ethyl-ketone (MEK), benzene (bzene), xylene (X-ylene), ethyl acetate (EA), acetone, and acetone. Since it is well soluble in mixed solvents such as alcohols, these are used as solvents to prepare a coating solution. Some of the adhesive resins are difficult to dissolve in the solvent. However, EVA, EAA, EEA, EMA, etc., which contain less than 80% of APP and ethylene, are soluble in a solvent mixed with toluene, toluene and other solvents when the heat is heated to about 50 ° C to 80 ° C. Therefore, these are also heated to form a coating liquid. As described above, a hot-melt adhesive layer coating liquid in a paint form obtained by dissolving an adhesive polymer, a tackifier, and a wax, which can be dissolved in a solvent, is obtained. The composition ratio of the solvent and the solid content in the composition of the coating solution may be composed of 20 to 50 weight ratio of the solid content with respect to the solvent. The hot-melt adhesive layer coating liquid obtained as described above is coated on a plastic film using a roll coater to obtain a laminating film.
