Abstract:
The present invention is directed to an unitized cover and transfer layer for hygiene applications that have the appearance, strength, and drape of a nonwoven and the surface characteristics of a film. The lightweight apertured film surface the present invention is comprised of a series of void spaces that act to collect liquids and channel such liquid into an associated underlying absorbent layer, while reducing potential release of particulates inherent to the absorbent layer. Further, the unitized cover and transfer layer of the present invention exhibits significantly reduced frictional noise and discomfort induced by prolonged contact.
