Abstract

See full text

A multilayer film is provided with a slippery surface layer by crystallization in an underlying layer which results in the deformation of an overlying surface layer without the use of particulate slip agents. The films may be formed by alternating layers of a naphthalene dicarboxylic acid polyester and a terephthalic acid polyester.
