Abstract
A composition has been made for biopolyester films, preferably polylactic acid (PLA) films, having a low coefficient of friction for improved sliding properties, while maintaining a low haze value for good transparency. The composition, made from a masterbatch of specific additives, produces a film that achieves a haze of two percent or less (measured by ASTM D1003) and a dynamic coefficient of friction of 0.35 or less (measured by ASTM D1894-01).
