Abstract
Soft resin compositions comprising a polyethylene resin (A) and an ethylene/α-olefin random copolymer (B) comprising ethylene and an α-olefin having 3 to 20 carbon atoms at a specific proportion, or an ethylene/α-olefin copolymer resin composition comprising a linear ethylene/α-olefin copolymer (A-α) comprising ethylene and an α-olefin having 4 to 20 carbon atoms and a long-chain branched ethylene/α-olefin random copolymer (B-α) comprising ethylene and an α-olefin having 3 to 20 carbon atoms in a specific proportion, wherein a density and MFR of the polyethylene resin (A) and the copolymer (A-α), and a density, MFR, intrinsic viscosity, glass transition temperature crystallinity, molecular weight distribution, B value and gη* values of the copolymers (B) and (B-α) are each in a specific range.
