  • Propylene polymer resins
    Patent number: 12325764
    Abstract: Propylene-based polymer resins and related compositions and processes are disclosed. The propylene polymer resins have high isotacticity and moderately high xylene soluble content. The polymer resins provide extruded sheets suitable for thermo forming that exhibit both sag resistance and ease of draw.
    Type: Grant

  • Resin compositions for producing biaxially oriented polypropylene films
    Publication number: 20070167576
    Abstract: Polypropylene resin compositions are provided that are useful in the production of biaxially oriented polypropylene films (BOPPs). 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.
