发明名称 Laminate
摘要 A laminate comprising a layer of a composition (A) of 100 parts by weight of a hydrolyzed ethylene-vinyl acetate copolymer having an ethylene content of 20 to 55% by mole and a degree of hydrolysis of at least 90% by mole and 1 to 100 parts by weight of a thermoplastic polyester having a glass transition temperature of -50 DEG to 25 DEG C. and a heat of fusion of not more than 30 joules/g, the acid component of the polyester being a mixture of 20 to 70% by mole of an aromatic dicarboxylic acid and 80 to 30% by mole of an aliphatic dicarboxylic acid, and the glycol component of the polyester being an alkylene glycol having 2 to 6 carbon atoms; and a layer of a composition (B) of at least one polymer selected from the group consisting of a polyolefin, a polystyrene, a polyvinyl chloride, a polyamide, a polycarbonate and a polyester having a glass transition temperature of not less than 30 DEG C. The laminate of the invention has improved flex crack resistance, drawability and heat moldability as well as excellent gas impermeability.
