ETHYLENE-VINYL ALCOHOL COPOLYMER COMPOSITION, MULTILAYERED SHEET AND SECONDARY MOLDED ARTICLE THEREOF USING SAME

摘要

Disclosed is an EVOH resin composition comprising 2 types of EVOH resins having a different ethylene content and saponification degree from each other. The EVOH resin composition can reduce the occurrence of streaks with retaining gas-barrier property even when applying to vacuum-pressure forming. The use of the resin composition also make it possible to provide a method for producing a container such as cup having excellent gas-barrier property and appearance by vacuum-pressure forming and the like.
