Patent ID: 6841583

Claim:
A composition comprising an ethylene/α-olefin copolymer (A) and a blowing agent (B), wherein the ethylene/α-olefin copolymer (A) comprises: 5 to 95 parts by weight of an ethylene/α-olefin copolymer (A1) having a density of not less than 0.880 g/cm 3 and less than 0.900 g/cm 3 and a melt flow rate determined according to ASTM D 1238 at a temperature of 190° C., and a load of 2.16 kg of 0.1 to 50 g/10 min, and 5 to 95 parts by weight of an ethylene/α-olefin copolymer (A2) having a density of 0.900 to 0.930 g/cm 3 , a melt flow rate determined according to ASTM D 1238 at a temperature of 190° C., and a load of 2.16 kg of 0.1 to 50 g/10 mm, a main melting point peak at a position of not higher than 110° C. and a surface hardness of 30 to 70 in terms of a Shore D hardness determined according to ASTM D 2240, the total of said components (A1) and (A2) being 100 parts by weight.
