  • Polypropylene blends for non-woven production
    Patent number: 8466235
    Abstract: Polypropylene resin compositions are provided that are useful in the production of thermoformed articles and biaxially oriented polypropylene films (BOPPs), tapes and fibers. The resins of the present invention are blends of high crystalline (low solubles) polypropylene homopolymer and an ethylene/propylene random copolymer (RCP). These blends can be used to replace standard high solubles BOPP grade polypropylene homopolymers. In addition, the use of high crystalline polypropylene homopolymers in the blends imparts improved stiffness to the finished films while maintaining good processability of the blends. Such polypropylene compositions are effectively produced by in-reactor blending of a high crystalline propylene homopolymer and a propylene/ethylene random copolymer.
