Abstract
The present invention relates to an opaque, biaxially oriented polymeric film having a thermoplastic polymer matrix material within which is located a stratum of voids. The voids are formed during orientation by a cavitating agent which is a particle of a cyclic olefinic copolymer. The solid particle is phase-distinct and incompatible with the matrix material.
