COINJECTION STRETCH BLOW MOLDED CONTAINER

摘要

The coinjection stretch blow molded container of the present invention comprises a layer of thermoplastic polyester (A) that has specific properties and a layer of ethylene-vinyl alcohol copolymer resin composition (B) that includes specific minor components and has specific properties, and the thickness ratio of the layer of thermoplastic polyester (A) to the layer of ethylene-vinyl alcohol copolymer resin composition (B) {layer (A)/layer (B in the container body is in the specific range. The coinjection stretch blow molded container is excellent in gas barrier property and in impact delamination resistance etc., and it can be stably produced in long-run working lines,
