Abstract

PURPOSE: To manufacture the title film having excellent antistatic properties, transparency, anti-block properties, etc., by compounding a polypropylene resin containing an inorganic filler with a mixture of polypropylene and an antistatic agent, pelletizing the composition, and extruding to a film followed by drawing.
CONSTITUTION: (A) 0.05W50 wt% of a pelletized composition obtained by the extrusion pelletizing (at 150W320°C) of a mixture comprising (a) 100 parts by weight of a polypropylene resin, (b) 0.2W5 parts of an inorganic filler (e.g. fine powders of silica gel, zinc oxide, etc.) and (c) 0W70 parts of polyethylene or an ethylene- vinyl acetate copolymer (vinyl acetate content of ≤ 40 wt%), is mixed with (B) 45W99.85 wt% of a polypropylene resin and (C) 0.1W5 wt% of an antistatic agent. The mixture thus obtained is molten at 150W320°C, pelletized, formed to a film, and oriented.
