PURPOSE: To provide the titled film having excellent blocking resistance, transparency and hue, by blending an ethylene polymer film with a mixture of hydrated aluminum silicate having a specified particle size and fired aluminum silicate. n CONSTITUTION: Hydrated aluminum silicate (a) having an average particle size of 0.1W2μm, pref. 0.3W1.5μm (e.g. kaolin exhibiting a loss on ignition of 10W16wt% and contg. not more than 5wt% components other than Al 2 O 3 and SiO 2 ) is mixed with fired aluminum silicate (b) having an average particle size of 0.5W5μm, pref. 0.8W3μm (e.g., kaolin exhibiting a loss on ignition of not more than 2wt% and contg. not more than 5wt% components other than Al 2 O 3 and SiO 2 ) in a weight ratio of 10W95:90W5 to obtain a mixture (B). A film (A) composed of at least one ethylene polymer selected from the group consisting of ethylene copolymers mainly composed of medium/low-density PE, ethylene is blended with 0.01W1wt% (based on the amount of the component A) component B. n COPYRIGHT: (C)1987,JPO&Japio |
