ABSTRACT:
Disclosed is an ethylene copolymer composition having a density of 0.980 to 0.955 g/cm.sup.3 and a melt flow rate (MFR) of 0.1 to 100 g/10 min., which is formed from two kinds of ethylene/.alpha.-olefin copolymers having specific properties and having density and MFR different from each other. The ethylene copolymer composition of the invention is excellent in melt tension and flow index within the high-shear-region, and able to form films of high transparency, high mechanical strength and blocking resistance.
