PURPOSE:To improve the optical properties such as transparency by using a linear low-density PE, a specified PE modified with maleic anhydride, and an ethylene/unsaturated ester copolymer as the constituents. CONSTITUTION:100 pts.wt. linear low-density PE having 3 a density of 0.895-0.940g/cm and a melt flow rate of 0.1-90g/10min obtained by copolymerizing ethylene and a 3-18C alpha-olefin, is mixed with 0.01-20 pts.wt. PE having a density of at least 0.930g/cm<3> and/or maleic anhydride modified PE obtained by modifying 100 pts.wt. PE with 0.01-5 pts.wt. maleic anhydride; and 0.01-20 pts.wt. ethylene/unsaturated ester copolymer having a melt flow rate of 10-300g/10min and an unsaturated ester content of 5-50wt.%. |
