PURPOSE:To improve adhesiveness stretchability, and interlaminar adhesive strength by compounding an ethylene-propylene-diene terpolymer rubber, an ethylene-vinyl acetate copolymer, and a specific polyester. CONSTITUTION:35-65wt.% ethylene-propylene-diene terpolymer rubber having an ethylene content of 60-69mol%, a propylene content of 30-40mol%, a diene content of 1-10mol%, and an MI of 0.1-5.0g/10min, 25-60wt.% ethylene-vinyl acetate copolymer having a vinyl acetate content of 5-30wt.% and an MI of 0.2-25g/10min, and 5-40wt.% satd. polyester having a b.p. of 110-180 deg.C are melt mixed at 150-180 deg.C to give a thermoplastic elastomer compsn., which is formed by inflation into an elastomer film having a thickness of 15-120mum. The film is laminated with a (nonwoven) fabric having a density of 20-100g/m<2> at 100-200 deg.C and 1-6kgf/cm<2> to give a composite film. |
