ABSTRACT:
Films of linear ethylene polymers, particularly copolymers of ethylene and alpha-olefins of 4 to 10 carbon atoms (LLDPE), containing up to about 15 weight percent of a 1:3 to 3:1 ratio of polystyrene or poly(para-methylstyrene), and impact polymer, e.g., impact polystyrene, exhibit excellent film properties and improved blocking.
