Abstract
A resin composition comprising the following components (A), (B) and (C), wherein the content of component (A) is from 10 to 90 wt %, component (B):component (C)=from 10:1 to 1:5 (weight ratio), the intrinsic viscosity [.eta.] is in the range from 0.17 to 0.40 m.sup.3 /kg, and the density is in the range from 935 to 968 kg/m.sup.3 : Component (A): a homopolymer of ethylene or a copolymer of ethylene having an .alpha.-olefin content of from 0 to 0.5 wt %, and an intrinsic viscosity [.eta.] of from 0.035 to 0.17 m.sup.3 /kg, Component (B): a homopolymer of ethylene or a copolymer of ethylene having an .alpha.-olefin content of from 0 to 0.5 wt %, and an intrinsic viscosity [.eta.] of from 0.2 to 1.0 m.sup.3 /kg, and Component (C): a copolymer of ethylene having an .alpha.-olefin content of from 0.7 to 15 wt %, and an intrinsic viscosity [.eta.] of from 0.2 to 1.0 m.sup.3 /kg.
