Abstract
Disclosed is an integral film comprising a transparent polymeric substrate having a surface bearing polymeric beads, wherein the swell ratio, the size, and the laydown of the beads are selected so as to provide both a one sided static friction coefficient of not more than 0.68 and an internal haze value of not more than 0.1. The film provides an improved combination of slip and optical properties.
