Title:

POLYPROPYLENE FILM ABD MULTILAYERED POLYPROPYLENE FILM

Document Type and Number:

WIPO Patent Application WO/2000/011079

Kind Code:

A1

Abstract:

A film made of a polypropylene composition which comprises crystalline polypropylene and a propylene/$g(a)-olefin copolymer having an intrinsic viscosity [$g(h)]¿RC? of 6.5 dl/g or lower and in which the ratio of the intrinsic viscosity of the copolymer [$g(h)]¿RC? to that of the crystalline polypropylene [$g(h)]¿PP? is from 0.6 to 1.2 and the product of that ratio and the weight ratio of the polypropylene to the copolymer, ([$g(h)]¿RC?/[$g(h)]¿PP?)x(W¿PP?/W¿RC?), is in the range of 0.2 to 4.5; and a multilayered film having at least one layer of the film.
