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.
