<p>PROBLEM TO BE SOLVED: To provide a polyethylene composition capable of producing a film having good processability, and excellent opening property, tear strength and transparency.SOLUTION: A film forming polyethylene composition comprising an ethylene-α-olefin copolymer (A), high density polyethylene (B) and high pressure process low density polyethylene (C) satisfying the following requirements (a) and (b), and containing (B) pts.wt and (C) pts.wt per 100 pts.wt of (A), is used. The requirement (a): vinylidene group amount (Vd) is 1.2 pieces/10C or more and 2.1 pieces/10C or less and melt flow rate (MFR) (measurement condition: 190°C, 2.16 kg load) is 0.1 g/10 minutes or more and 6.0 g/10 minutes or less. The requirement (b): melt tension (measurement condition: temperature of 190°C, take-up speed of 0.5 m/minute) of 50 mN or more and 200 mN or less.</p> |
