PURPOSE: To obtain a blow-moldable polyethylene resin composition having excellent processability in blow molding, good transparency, low-temperature impact strength, and toughness and giving a lowly odorous molding. CONSTITUTION: This blow-moldable polyethylene resin composition comprises 30-95wt.% high-pressure process branched low-density polyethylene having a melt flow rate (at 190 deg.C) of 0.01-5g/10min and a density of 0.915-0.940g/cm<3> and 70-5wt.% ethylene/(α-olefin copolymer having a melt flow rate (at 190 deg.C) of 0.01-10g/10min, a density of 0.870-0.930cm/cm<3> , a single endothermic peak (as determined by DSC) whose top stands on a temperature in the range of 60-120 deg.C and a weight/average molecular weight/ number - average molecular weight ratio of 1.5-3.0 (as determined by GPC). |
