Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multilayer container, which retains the properties of a conventional multilayer container, such as a gas barrier property, and has a superior impact separation resistance. SOLUTION: The multilayer container is formed through a coinjection draw/blow molding process, and consists of a layer of thermoplastic polyester (A) and a layer of ethylene-vinyl alcohol copolymer resin composition (B). The ethylene-vinyl alcohol copolymer resin composition (B) contains a compound containing an ionic functional group. COPYRIGHT: (C)2005,JPO&NCIPI
