Provided are resin compositions comprising: (A) 60 to 95% by weight of an ethylene-vinyl acetate copolymer having an ethylene content of 20 to 65 mol% and a saponification degree of the vinyl acetate component of at least 96%, (B) 4.5 to 39.5% by weight of an ethylene-vinyl acetate copolymer having an ethylene content of 60 to 98 mol%, and (C) at least 0.5% by weight of a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 68 to 98 mol% and a saponification degree of the vinyl acetate component of at least 20%, the incorporation ratio of (C) based on the sum of (B) and (C) being not more than 38% by weight. The resin compositions of the present invention have markedly improved flexibility without deteriorating transparency and gas barrier properties as compared with conventional saponified products of ethylene-vinyl acetate copolymers. Multilayered structures comprising at least one layer of the composition have excellent resistance to falling shock, flexural resistance, prevention of air-back, skin-pack adaptability and shrink-packaging capability and are hence of great value for packaging various goods. |
