Abstract
Unitary films and laminates thereof are provided having at least first and second film segments which extend adjacent one another and are permanently joined together. The multi-segment films include a pattern of surface embossments on a surface of the first film segment and a pattern of apertures extending through the second film segment. 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 breathability and/or elasticity. The unitary films and laminates thereof are well suited, for example, for use as outer covers in personal care articles.
