PROBLEM TO BE SOLVED: To obtain a polyethylene composition which is excellent in especially transparency and moldability into preforms and can give blow moldings excellent in shrinking properties, stretchability and surface smoothness by mixing resins having specified properties with each other. SOLUTION: This composition comprises 10-99wt.% ethylene/α-olefin copolymer having a density of 0.880-0.960, a melt flow rate (at 190 deg.C under a load of 2.16kg) (MFR2.16 ) of 0.001-200, a ratio of MFR2.16 to MFR21.6 (wherein MFR21.6 is the melt flow rate (at 190 deg.C under A load of 21.6kg) of 10-20, a molecular weight distribution (Mw /Mn ) of 2.0-4.0 and a swell ratio (at 190 deg.C) of 1.35 or below and 1-90wt.% high-density polyethylene having an MFR2.16 of 0.01-100 and a density of 0.940 or above. |
