A resin composition containing less carboxylate group is obtained by contacting an ethylene-vinyl alcohol copolymer resin with an aqueous solution containing both carbon dioxide gas and at least one additive selected from the group consisting of an alkali metal salt (A) and a boron compound (B) and then melt kneading with a thermoplastic resin (G) other than EVOH.Type: GrantFiled: July 22, 2004Date of Patent: January 6, 2009Assignee: Kuraray Co., Ltd.Inventors: Naohiko Uchiumi, Kaoru Ikeda, Noriyuki Kida, Tetsuya Hara, Syukiti Kawamura
