ABSTRACT:
Apertured polymeric films for use as a liquid permeable facing material on absorbent products such as diapers and sanitary napkins is textured by a dual embossing process. The film is preferably embossed first with a pronounced, textile-like pattern, then embossed with a finely engraved finish roll to produce a thin, smooth film with a matte finish while retaining the appearance of the previously embossed pattern. The twice embossed film is soft, conformable, and more comfortable against the skin. The embossing sequence may be reversed for some applications.
