Title:
POLYETHYLENE-BASED RESIN COMPOSITION AND FILM MADE OF THE SAME
Document Type and Number:
Japanese Patent JP2017061653
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyethylene-based resin composition having excellent molding processability, from which a molded body having an excellent balance in impact strength and rigidity can be manufactured.SOLUTION: The polyethylene-based resin composition comprises a high-pressure polyethylene (A) and an ethylene α-olefin copolymer (B) satisfying the following conditions (B-1) to (B-5). The conditions are: (B-1) an MFR of the copolymer is over 0.1 g/10 minutes and 10 g/10 minutes or less; (B-2) a density is 0.895 to 0.940 g/cm; (B-3) a molecular weight distribution Mw/Mn measured by gel permeation chromatography (GPC) is 3.0 to 5.5; (B-4) a minimum (gc) of a branch index g' in the molecular weight range from 100000 to 1000000 is 0.40 to 0.85; and (B-5) a (W+W) value obtained from an integrated elution curve measured by cross-fractionation chromatography (CFC) is 40 wt.% or more and 80 wt.% or less.SELECTED DRAWING: None
