PROBLEM TO BE SOLVED: To obtain a polyethylene composition which has excellent moldability and can give films having excellent transparency and mechanical properties by specifying the properties of the components and specifying the mixing ratio between them. SOLUTION: This composition comprises 50-94wt.% ethylene/α-olefin copolymer having a density of 0.880-0.960 and a melt flow rate (at 190 deg.C under a load of 2.16kg) (MFR2.16 ) of 0.01-200, 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, and a molecular weight distribution (Mw /Mn ) of 2.0-4.0 and 6-50wt.% high-pressure process low-density polyethylene having an MFR2.16 of 0.1-50 and satisfying the relationship: melt tension (at 190 deg.C)<-9log (MFR2.16 )+10.
