Patent ID: 7473735

Claim:
A resin composition comprising: an unmodified ethylene-vinyl alcohol copolymer resin composition (F): containing 0.1 to 20 μmol/g, in terms of alkali metal, of an alkali metal salt (A); yielding 0 to 2 μmol/g of a carboxylate group (C1) upon extraction by immersion treatment in water at 95° C. for 10 hours; and yielding 0 to 40 μmol/g of a carboxylate group (C2) upon extraction by immersion treatment in a 0.05 N aqueous sodium hydroxide solution at 95° C. for 10 hours; and a thermoplastic resin (G) comprising at least one resin selected from the group consisting of polyolefin (G1), polyamide (G2) and a modified ethylene-vinyl alcohol copolymer (G3) having an ethylene content of 5 to 55 mol % and containing 0.3 to 40 mol % of the following structural unit (I): wherein R 1 , R 2 , R 3 and R 4 each denote a hydrogen atom, an aliphatic hydrocarbon group having 1 to 10 carbon atoms, an alicyclic hydrocarbon group having 3 to 10 carbon atoms or an aromatic hydrocarbon group having 6 to 10 carbon atoms; R 1 , R 2 , R 3 and R 4 may be the same or different; R 3 and R 4 may be combined together; and R 1 , R 2 , R 3 and R 4 each may have a hydroxyl group, a carboxyl group or a halogen atom.
