Abstract

A paper-containing laminate is disclosed which comprises: (a) an outer layer of opaque biaxially oriented polymer film structure of lustrous satin appearance which comprises: (i) a thermoplastic polymer matrix core having an upper surface and a lower surface and within which is located a strata of voids; positioned at least substantially within at least a substantial number of voids is at least one spherical void-initiating particle which is phase distinct and incompatible with the matrix material, the void space occupied by said particle being substantially less than the volume of said void, with one generally cross-sectional dimension of said particle at least approximating a corresponding cross-sectional dimension of said void; (ii) a void-free thermoplastic skin layer adhering to at least the upper surface of said core layer, said skin layer being of a thickness such that the outer, exposed surface thereof does not, at least substantially, manifest the surface irregularities of said core layer; the population of voids in said core and the thickness of said core being such as to cause a degree of opacity of less than 70% light transmission; and, (b) a substrate web layer selected from the group consisting of paper and non-woven tissue, the upper surface of which is affixed directly or indirectly to the lower surface of the core layer (a)(i) with or without a laminating adhesive interposed between said surfaces.
