Abstract: A film product and a method of making the same are provided, the film product comprising a metallocene catalyzed polypropylene and a tenacity of at least about 2.5 g/den is provided. The film product is capable of being drawn at a draw ratio of from about 5.0:1 to about 10.0:1. The film product is also capable of being processed into a slit tape product. A method of weaving a woven product from the slit tape product is also provided, wherein the woven product may have a tenacity within about 10.0 percent of the tenacity of the film product.

Abstract: A polypropylene material is prepared from a blend of heterophasic propylene copolymers and propylene homopolymers. The material is prepared by blending the polymers while they are in a molten state, and forming a film or sheet from the polymer blend. The material has particular application to forming slit film tapes and similar materials. The resultant materials exhibit increased tenacity, elongation and toughness and greater surface roughness as compared to those materials prepared solely from propylene homopolymers.

Abstract translation: 聚丙烯材料由多相丙烯共聚物和丙烯均聚物的共混物制备。 材料通过在聚合物处于熔融状态下共混而制备，并从聚合物共混物形成膜或片材。 该材料特别适用于形成切片胶带和类似材料。 与仅由丙烯均聚物制备的那些材料相比，所得材料表现出增强的韧性，伸长率和韧性以及更大的表面粗糙度。
