Patent number: 7754814Abstract: A polypropylene material is prepared from a blend of polypropylene impact copolymer and high crystallinity polypropylene having less than 2 percent xylene solubles. 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.
