<p>PROBLEM TO BE SOLVED: To obtain a multilayer plastic container with improved high-impact ply separation and hot fill filling ply separation characteristics, and furthermore superior in transparency. SOLUTION: This multilayer plastic container is made of thermoplastic polyester A outside and inside layers and a resin B intermediate layer. The resin B is made of ethylene-vinyl alcohol copolymer resin C with ethylene content 15-70 mole percentage, polyamide resin D and ethylene/unsaturated carvone copolymer resin E, and also satisfies equations: 0.5<=Wc/(Wc+Wd+We)<=0.99 and 0.02 <=Wd/(Wd+We)<=0.7. Here, Wc represents the weight of ethylene-vinyl alcohol copolymer C, Wd the weight of polyamide resin D and We the weight of ethylene/unsaturated carvone copolymer E.</p> |
