Patent ID: 7064158

Claim:
A resin composition comprising ethylene-vinyl alcohol copolymer (A), a thermoplastic resin (B) other than the ethylene-vinyl alcohol copolymer (A), and a transition metal salt (C), wherein the ethylene-vinyl alcohol copolymer (A) is contained in an amount of 70 to 99.9% by weight and the thermoplastic resin (B) is contained in an amount of 0.1 to 30% by weight, an ethylene content ETa (mol %) and a degree of saponification SDa (%) of the ethylene-vinyl alcohol copolymer (A) satisfy the following equations (1) and (2): 25≦ETa≦55 (1) 90≦SDa<99 (2), the thermoplastic resin (B) comprises a carbon-carbon double bond which does not encompass multiple bonds contained in aromatic rings, and the transition metal salt (C) is contained in a ratio of 1 to 5000 ppm in terms of metal element, based on a total weight of the ethylene-vinyl alcohol copolymer (A) and the thermoplastic resin (B).
