摘要: A breathable film having improved processing properties and reduced cost includes a breathable film-forming layer composition including a matrix polymer, a particulate organic filler, and a compatibilizer. The particulate organic filler is incompatible with the matrix polymer and tends to agglomerate when mixed with the matrix polymer alone. The compatibilizer achieves thermodynamic equilibrium between the matrix polymer and filler within a defined filler particle size range suitable for producing stretched breathable film. The film processes more easily than breathable films containing inorganic fillers, and is less expensive to manufacture.

摘要: Unitary films are provided having at least first and second film segments which extend adjacent one another and are permanently joined together. The first and second segments have different compositions whereby the unitary film includes distinct segments having varied physical properties such as, for example, varied levels of high water-vapor transmission rates and/or elasticity. The unitary films and laminates thereof are well suited for use as outer covers in personal care articles and various other barrier articles.
