Abstract
A process includes combining a metallocene catalyzed polypropylene with a nucleator and a slip agent to form a composition, and forming a cast film from the composition. The slip agent may exhibit an increased slip bloom rate within the cast film relative to the slip bloom rate exhibited by the slip agent in an otherwise identical cast film in which the nucleator is not present in the cast film. The cast film may exhibit a coefficient of friction that is less than a coefficient of friction of an otherwise identical cast film in which the nucleator is not present in the cast film.
