Abstract

The invention is a polymer resin that includes between about 20 and 200 ppm of an inert particulate additive, preferably selected from the group consisting of surface-modified talc and surface-modified calcium carbonate. The polymer resin is capable of being formed into low-haze, high-clarity bottles and films possessing reduced coefficient of friction.
