| 20090029098 | Resin Composition for Improved Slit Film - Slit films and processes of forming the same are generally described herein. In one embodiment, the slit films include an impact copolymer (ICP) formed of polypropylene and less than about 8 wt. % total ethylene, wherein the slit film exhibits less shrinkage and higher tenacity than a slit film formed from an ICP having greater than 10 wt. % ethylene. In one embodiment, the slit films include an impact copolymer including propylene and ethylene, wherein the slit film is absent another polymer. | 01-29-2009 |
| 20090155614 | Polypropylene Materials and Method of Preparing Polypropylene Materials - A polypropylene material may be prepared from a blend of heterophasic propylene copolymers and propylene homopolymers. The material may be prepared by blending the polymers while they are in a molten state, and forming a film or sheet from the polymer blend. The materials may also be formed as coextruded materials or as ternary blends with a polyethylene or a single phase random propylene copolymer. The blends and neat polymers have particular application to forming slit film tapes and similar materials. The resultant materials may exhibit increased tenacity, elongation and toughness and greater surface roughness as compared to those materials prepared solely from propylene homopolymers. | 06-18-2009 |
