PURPOSE:To obtain the title film excellent in antitaticity, antiblocking property and oil-whitening resistance by incorporating polypropylene with a specific amine derivative, specific amide derivative and anti-blocking agent followed by extrusion drawing. CONSTITUTION:A resin composition prepared by incorporating (A) 100 pts.wt. of polypropylene with (B) 0.05-0.2 pts.wt. of a polyoxyethylenealkylamine derivative of formula I (R' is 12-18C aliphatic hydrocarbon group; m and n are each integer: $1, m+n=2-6), pref. diethanolalkylamine of formula II, (C) an polyoxyethylenealakylamide derivative of formula III (R is 9-11C aliphatic hydrocarbon group; p and q are similar to m and n), pref. diethanolalkylamide of formula IV at such an amount as to be 3-20 in the weight ratio B/C, and (D) 0.01-0.5 pts.wt. of an anti-blocking agent, pref. silica 0.5-10mum in mean particle size, is put to melt extrusion and then drawn at a temperature lower than the melting point of the component A, thus obtaining the objective film. |
