PROBLEM TO BE SOLVED: To provide a polyethylene resin composition having excellent extrusion moldability and inflation moldability, a heavy-duty packaging film made of the resin composition and having high strength and a heavy-duty packaging bag made of the film and having high strength. SOLUTION: The resin composition contains (A) an ethylene-α-olefin copolymer having an ethylene-based monomer unit and a 3-20Cα-olefin monomer unit, having a flow activation energy (Ea) of≥35 kJ/mol and a melt flow rate ratio (MFRR) of≥30 and (B) an ethylenic polymer other than the component A. The content of the component A is 60-95 wt.% and that of the component B is 40-5 wt.% based on 100 wt.% of the sum of the components A and B. COPYRIGHT: (C)2005,JPO&NCIPI
