摘要：PROBLEM TO BE SOLVED: To provide a polyolefin film excellent in transparency and heat sealing property. SOLUTION: The resin composition for films is composed of (A) 50-90 wt.% ethylene-α-olefin copolymer having 0.900-0.940 g/cm<SP>3</SP>and 0.01-50 g/10 min MFR in which a temperature (Tm(°C)) and a density (d) at a maximum peak position of an endothermic curve measured by DSC satisfy the relational expression: Tm<400×d-248, (B) 1-30 wt.% ethylene-based polymer having 0.1-50 g/10 min MFR and 0.900-0.940 g/cm<SP>3</SP>density in which a melt tension (MT) and an MFR satisfy the relational expression: 40×(MFR)<SP>-0.67</SP>≤MT≤250×(MFR)<SP>-0.67</SP>and (C) 5-40 wt.% ethylene-α-olefin copolymer having 0.1-50 g/10 min MFR and 0.860-0.895 g/cm<SP>3</SP>density.
