ABSTRACT:
Disclosed is a resin composition excellent in its drawability, which comprises (A) a saponified ethylene-vinyl ester copolymer having an ethylene content of 20 to 55 mole % and a saponification degree of at least 95%, (B) a saponified ethylene-vinyl ester copolymer having an ethylene content of 25 to 60 mole % and a saponification degree of at least 90%, the ethylene content of the saponified copolymer (B) being higher by at least 3 mole % than the ethylene content of the saponified copolymer (A), and (C) a polyamide, wherein the weight ratio of the saponified copolymer (A) to the saponified copolymer (B) is in the range of from 90/10 to 10/90 and the weight ratio of the sum of the saponified copolymers (A) and (B) to the polyamide (C) is in the range of from 95/5 to 5/95. The resin compositions have excellent gas barrier properties and can be molded into films or sheets or laminated with other film-forming materials. Molded articles such as cups and other vessels having gas barrier properties can be obtained by molding the laminated films prepared from the resin compositions.
