PROBLEM TO BE SOLVED: To obtain the subject film capable of manifesting excellent slipperiness, transparency, etc., just after heat shrink packaging by including a polypropylene- based resin, a linear low-density polyethylene resin and silicone-based fine particles therein. SOLUTION: This film comprises (A) 100 pts.wt. polypropylene-based resin, (B) 1-30 pts.wt. linear low-density polyethylene resin having 0.880-0.925 g/cm<3> density and (C) 0.01-2 pts.wt. silicone-based fine particles having 0.5-8μm average particle diameter. The component C is preferably fine particles obtained by copolymerizing an organopolysiloxane represented by formula I [Rs are each a 1-12C monovalent hydrocarbon and >=50 mol.% of the whole Rs is methyl; X is a radical-polymerizable functional group-containing organic group, preferably a group represented by formula II (R<1> is a 3-20C bivalent organic group which may contain a heteroatom; R<2> is H or methyl) or a group represented by formula III; (n) is an integer of 5-200] with an uncross-linkable radical- polymerizable monomer and a cross-linkable radical-polymerizable monomer. |
