Abstract:
An ethylene-vinyl alcohol copolymer resin having low odor of acetic acid and good long-run workability is provided. The ethylene-vinyl alcohol copolymer resin which contains an alkali metal salt (A) and has a very low extractable carboxylate content is obtained by a method including contacting the ethylene-vinyl alcohol copolymer resin with an aqueous solution containing carbon dioxide gas.
