Abstract:
A resin composition comprising:(A) an ethylene-&agr;-olefin copolymer meeting the following conditions (A-1), (A-2) and (A-3): (A-1) the melt flow rate (MFR) is in the range of from 0.5 to 100 g/10 min, (A-2) the density is in the range of from 860 to 920 kg/m3, and (A-3) the highest melting peak temperature determined with a differential scanning calorimeter is in the range of from 50Â° C. to 110Â° C.; (B) an ethylene homopolymer or ethylene-&agr;-olefin copolymer meeting the following conditions (B-1), an (B-2) and (B-3): (B-1) the melt flow rate (MFR) is in the range of from 0.5 to 100 g/10 min, (B-2) the density is in the range of from 910 to 980 kg/m3, and (B-3) the highest melting peak temperature determined with a differential scanning calorimeter is in the range of from 110Â° C. to 135Â° C.; and (C) a low-density polyethylene as high-pressure radical polymerization product which meets the following conditions (C-1) and (C-2): (C-1) the melt flow rate (MFR) is in the range of from 0.5 to 100 g/10 min, and (C-2) the swell ratio (SR) is in the range of from 1.3 to 2.0, said resin composition comprising 40 to 90% by weight of component (A), 5 to 30% by weight of component (B) and 5 to 30% by weight of component (C) when the total proportion of component (A), component (B) and component (C) is taken as 100% by weight.
