Claim:
1. A polyethylene resin composition comprising from 20 to 80 wt % of a high-density polyethylene (A) satisfying characteristics (a) and (b) described below, from 0 to 50 wt % of a linear low-density polyethylene (B1) satisfying characteristics (c) and (d) described below, and from 5 to 40 wt % of an ethylene-based polymer satisfying characteristics (e) to (h) described below, a total of (A), (B1), and (C) being 100 wt %: (a) Density is from 945 to 970 kg/m (b) MFR measured at 190° and load of 2.16 kg in conformance with JIS K69221 is from 0.1 to 15.0 g/10 min; (c) Density is from 890 to 915 kg/m (d) MFR measured at 190° and load of 2.16 kg in conformance with JIS K6922-1 is from 0.1 to 15.0 g/10 min; (e) Density is from 930 to 960 kg/m (f) MFR measured at 190° and load of 2.16 kg in conformance with JIS K6922-1 is from 0.1 to 15.0 g/10 min; (g) Two peaks appear in molecular weight measurement by gel permeation chromatography, and a ratio (Mw/Mn) of weight-average molecular weight (Mw) to number-average molecular weight (Mn) is from 2.0 to 7.0; (h) A fraction having Mn of not less than 100,000 obtained by molecular-weight fractionation has 0.15 or more long-chain branches per 1,000 carbons of a main chain.
