Abstract
PURPOSE:To obtain a film having excellent physical properties, by containing an ethylenic polymer having specific range values in a wt. average MW, a wt. average MW/number average MW ratio and density in a polyethylenic film stretched by 1.1-4.0 times and also specifying the density and haze value of said film. CONSTITUTION:A polyethylenic film obtained using polyethylene containing an ethylenic polymer having a wt. average MW of 150000-300000, a wt. average MW/number average MW ratio of 10 or more and density of 0.935g/cm<3> or more is stretched by 1.1-4.0 times. Further, the density of said polyethylenic film is set to 0.930g/cm<3> or more and the haze value thereof is set to below 5%. By this method, since transparency becomes transparent and viscosity at the time of heat-sealing is high, a film having a good tack property and an excellent tearing property while holding good sealability and sufficient rigidity can be obtained.
