摘要: An elastomer film of a thermoplastic elastomer composition comprising 30-70 weight % of an ethylene-propylene-diene copolymer and 70-30 weight % of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 5-30 weight % and a melt index of 0.2-25 g/10 minutes, the elastomer film having a thickness of 10-60 .mu.m, and a draw ratio expressed by a heat shrinkage ratio at 50.degree. C. which is 5-35% in an MD direction and 5-25% in a TD direction, the ratio of the draw ratio in an MD direction to the draw ratio in a TD direction being 3 or less, is produced by an air-cooled inflation method.
