Abstract: 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.

Abstract: Disclosed is a method of modifying polyethylene to increase its ability to resist the transmission of water vapor. The polyethylene is modified to increase long chain branching resulting in lower water vapor transmission rates in films prepared with the modified polyethylene. The polyethylene can be modified using peroxides, air and even by admixture with high long chain branching content polyethylene. The polyethylene, particularly when in the form of films, can be used for preparing packaging where sorption of flavor, aroma, or colorant compounds must be minimized.
