Abstract

A fluid pervious web suitable for use as a topsheet on an absorbent article is disclosed. The topsheet includes a fibrous and apertured, three-dimensional, macroscopically expanded. plastic web. The fibrous and apertured, three-dimensional, macroscopically expanded, plastic web permits bodily fluids to penetrate while providing an improved, less plastic-like feel and visual aesthetics.
