Abstract
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 MD tear strength and stiffness, but improves them.
