发明名称 COMPOSITE HINGE SHEET FOR LASER-MARKING MULTILAYER LAMINATE FOR ELECTRONIC PASSPORT, LASER-MARKING MULTILAYER LAMINATE FOR ELECTRONIC PASSPORT, AND ELECTRONIC PASSPORT
摘要 Disclosed is a composite hinge sheet including thermoplastic resin layers 5 made of a thermoplastic resin formed on both surfaces of a woven-fabric like sheet 3 having multiple openings therein. The woven-fabric like sheet 3 includes woven fabric or non-woven fabric made of at least one type selected from polyester, polyamide and polypropylene. The thermoplastic resin layers 5 include, as a raw material, resin having Shore A surface hardness flexibility of 85 or greater and Shore D surface hardness flexibility of less than 70. A part of the thermoplastic resin enters the openings in the woven-fabric like sheet 5, thus blocking all the openings, so that the thermoplastic resin layers 5 are integrated with the woven-fabric like sheet 3. The composite hinge sheet has excellent tearing and tensile strength, is resistant to light and heat in the binding part thereof, and has excellent resistance to repeated bending.
