摘要

P To provide a gas barrier thermoplastic polyester-based resin laminated body capable of preventing interlayer peeling and suppressing opacification, a preform for stretch blow molding having the polyester-based resin laminated body and a packaging container formed by molding the preform for stretch blow molding. PSOLUTION: The preform for stretch blow molding is molded having a gas barrier thermoplastic polyester-based resin composition (P) including: a first thermoplastic polyester resin (A) of 10-90 pts.wt containing a diol component having a straight-chain hydrocarbon and a dicarboxylic acid; a second thermoplastic polyester resin (B) of 8-85 pts.wt containing a diol component having an alicyclic hydrocarbon and a dicarboxylic acid; and an aromatic polyamide resin (C) of 0.1-43 pts.wt., and a portion laminating a thermoplastic polyester-based resin (Q) ON at least one surface side of the resin composition (P). Further and the packaging container is formed by the stretch blow molding of the preform. PCOPYRIGHT: (C)2011 and JPO& INPIT
