Abstract

Disclosed is a molded article which is produced from a resin composition comprising a modified ethylene-(vinyl alcohol) copolymer (C-1) and a modified ethylene-(vinyl alcohol) copolymer (C-2), wherein the at least a part of the resin composition is cross-linked so as to have a gel fraction of 3 mass% or more. The modified ethylene-(vinyl alcohol) copolymer (C-1) is produced by modifying an unmodified ethylene-(vinyl alcohol) copolymer (A-1) with an epoxy compound (B-1) having a double bond, wherein the ratio of modification with the epoxy compound (B-1) having a double bond is 0.1 to 10 mol%. The modified ethylene-(vinyl alcohol) copolymer (C-2) is produced by modifying an unmodified ethylene-(vinyl alcohol) copolymer (A-2) with an epoxy compound (B-2) having no double bond, wherein the ratio of modification with the epoxy compound (B-2) having no double bond is 0.3 to 40 mol%. It becomes possible to provide a molded article which is excellent in hot water resistance, heat resistance, gas barrier properties, heat-sealing properties in a wide temperature range, thermal shrinkability properties and flexibility.
