PURPOSE: To upgrade the mechanical pass-through properties and the antistatic properties and, at the same time, improve the satisfactory shrink properties by adding specific components, limiting the longitudinal and the transverse shrinkage factors of a multilayer film at a specific temperature within a specified range and making the film matte.
CONSTITUTION: The specific components I are a propylene monopolymer and the like and 5-10C α-olefins or propylene and the like. One kind each of a monopolymer, a copolymer and a terpolymer of the described components or a mixture of two kinds or more of these copolymers, or a terpolymer blend of more kinds of these copolymers are used. The specific components II are either HDPE or a blend of two kinds of components, A, B. In addition, the blend component A is substantially HDPE and the blend component B is substantially a propylene homopolymer or the like. This multilayer polypropylene film contains components I, II, preferably with a shrinkage factor of 25-50% in the longitudinal direction at 120°C and a shrinkage factor of 30-60% in the transverse direction at 120°C and besides, is matte-treated.
