PROBLEM TO BE SOLVED: To obtain an ethylene resin composition having sufficient transparency and operability as a film and excellent stability during molding without harming its excellent mechanical properties and moldability. SOLUTION: This composition is obtained by blending 100 pts.wt. of an ethylene resin comprising 70-98 wt.% of an ethylene/α-olefin copolymer which is a copolymer of ethylene and a 3-20Cα-olefin satisfying the conditions (a), (b) and the like: (a) the density (D) is not less than 0.85 g/cm<3> and not more than 0.95 g/cm<3> , (b) the melt tension(MT) at 190 deg.C and the melt flow rate(MFR) satisfy the equation: log(MT)>=-0.9l×log(MFR)+0.06 [wherein MT: the melt tension (g); MFR: the melt flow rate (g/10 min)], and 30-2 wt.% of a low density polyethylene prepared by a high pressure radical method having the properties of (c)-(f): (c) MFR is 0.1-20 h/10 min, (d) the density is 0.915-0.935 g/cm<3> , (e) MT is 5-17 g, (f) the memory effect(ME) is 0.6-2.1, with 0.05-1.0 pt.wt. of an antioxidant and 0.01-0.8 pt.wt. of an antiblocking agent. |
