Abstract
A sanitary napkin having an improved release liner. The sanitary napkin includes a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. The backsheet has an inner surface and an outer surface. A pressure sensitive adhesive is positioned on the outer surface of the backsheet for securing the sanitary napkin in the crotch portion of a user's panty or undergarment. A release liner is releasably affixed to the adhesive in order to keep the adhesive from adhering to a surface other than the crotch portion of the panty prior to use. The release liner is a microapertured polymeric web.
