Abstract
A polyethylene resin composition which permits the bleeding additive contained therein to be bled at an increased rate even if it has a large molecular weight and, therefore, permits the bleeding agent to be bled to the surface of the resin in an amount sufficient for exhibiting its properties.The polyethylene resin composition comprises, as a main polymer (A), a high pressure process low-density polyethylene and, as a sub-polymer (B), at least one kind of polyethylene selected from the group consisting of a metallocene-type low-density polyethylene and a high pressure process low-density polyethylene having an MFR larger than that of the main polymer (A), the polyethylene resin composition being, further, blended with a bleeding additive.
