F-3332 PLASTIC BAGS OF BLENDS OF LINEAR ETHYLENE POLYMERS AND AROMATIC POLYMERS ABSTRACT OF THE DISCLOSURE Plastic bags are made from linear ethylene homopolymer or linear low density copolymers (LLDPE) blended with up to about 10 weight percent of an aromatic polymer, e.g., polystyrene or poly(para-methylstyrene), to improve the ease of opening the bags by reducing the blocking tendency of the film. Although ease of opening is improved the aromatic polymer does not adversely affect the other physical properties of the bag, such as machine direction (MD) tear strength and stiffness, but improves them.
