PROBLEM TO BE SOLVED: To provide an ethylenic copolymer composition having excellent formability and capable of giving a film having excellent transparency, mechanical strength and blocking resistance. SOLUTION: The ethylenic copolymer composition is composed of (A) a copolymer of ethylene and a 3-20Cα-olefin, having a density, melt flow rate(MFR), maximum peak of melting point by DSC and melt tension(MT) falling within respectively specific ranges and satisfying the relationship of MT<=2.2×MFR-0.84 and (B) a low-density polyethylene produced by high-pressure radical polymerization method and having a melt flow rate of 0.1-50 g/10 min at an A:B weight ratio of 99:1 to 60:40. |
