<P>PROBLEM TO BE SOLVED: To provide a multilayer container having a gas barrier property and transparency suitable as a packaging material of food which requires heat sterilization. <P>SOLUTION: The multilayer container is structured of 3 or more layers, a layer (X) essentially containing polypropylene, an adhesive layer (Y) consisting of an adhesive thermoplastic resin, and a gas barrier layer (Z) consisting of a polyamide resin composition (P). They are laminated in this order from the inner layer to the outer layer. The polyamide resin composition comprises a polyamide resin composition of 100 pts.mass which consists of a polyamide resin of 80-100 mass%, consisting of a diamine unit containing a methaxylylenediamine unit of ≥70 mol% and a dicarboxylic acid unit containing an adipic acid unit of 80-97 mol% and an isophthalic acid unit of 3-20 mol%, and a polyhexamethylene terephthalamide/polyhexamethylene isophthalamide copolymer of 20-0 mass%, and a crystallization promotor of 0.01-2 pts.mass which has an average particle diameter of 0.01-5 μm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
