Title:
ETHYLENE-VINYL ALCOHOL RESIN COMPOSITION, MULTILAYER STRUCTURE, MULTILAYER SHEET, CONTAINER, AND PACKAGING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/187454
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a resin composition exhibiting excellent retort resistance and property to inhibit burning in an operation lasting a long period of time. The present invention is a resin composition containing an ethylene-vinyl alcohol copolymer (A) having an ethylene content between 20 and 60 mol%, a polyamide resin (B), a carboxylic acid metal salt (C), and an unsaturated aldehyde (D), wherein the mass ratio of the ethylene-vinyl alcohol copolymer (A) relative to the polyamide resin (B) is between 60/40 and 95/5 when A/B, the content of the carboxylic acid metal salt (C) relative to the resin content is between 1 and 500 ppm in terms of metal element, and the content of the unsaturated aldehyde (D) relative to the resin content is between 0.05 and 50 ppm.
