Abstract
A multilayer opaque, biaxially oriented polymeric film structure. The film structure includes (a) a thermoplastic polymer matrix ire layer having a first surface and a second surface, within which is locate a strata of voids; positioned at least substantially within a substantial number of the voids is at least one spherical void-initiating particle which is phase distinct and incompatible with the matrix material, the void space occupied by the particle being substantially less than the volume of the void, with one generally cross-sectional dimension of the particle at least approximating a corresponding cross-sectional dimension of the void; the population of the voids in the core being such as to cause a significant degree of opacity; (b) at least one thermoplastic polymer intermediate layer having a first surface and a second surface, the second surface of the intermediate layer adhering to at least the first surface of the core layer, the intermediate layer including up to about 12% by weight of titanium dioxide contact pigment; and (c) a titanium dioxide-free, non-voided thermoplastic skin layer adhering to the first surface of the intermediate layer, the void-free skim layer and the intermediate layer together being of a thickness such that the outer surface of the skin code layer clues not, at least substantially, manifest the surface irregularities of the matrix core layer.
