Abstract

A multilayered apertured film wrapping element for an absorbent article is disclosed. At least one outer layer of the fluid-impervious plastic material has a continuous phase of a thermoplastic polymeric component and an immiscible, dispersed phase of a thermoplastic polymeric component having a lower melting point. The wrapping element is useful in applications involvin g heat sealing and similar thermal processes in absorbent articles, such as sanitary napkins, diapers, bandages, tampons, and the like.
