ABSTRACT:
Ethylene copolymer compositions comprise: an ethylene/.alpha.-olefin copolymer component comprising at least one ethylene/.alpha.-olefin copolymer having a density within a specific range, a melt flow rate (MFR) within a specific range, an amount of an n-decane-soluble portion within a specific range and a melt tension (MT) that satisfies a specific relation with the MFR; and a (co)polymer component comprising one (co)polymer selected from the group consisting of a low-density polyethylene obtained by high-pressure radical polymerization, a crystalline polyolefin and an olefin elastomer. The ethylene copolymer compositions are excellent in heat stability and moldability, and able to form films of high transparency, high mechanical strength and anti-blocking resistance.
