Abstract

Sanitary napkins are provided which include release surfaces disposed on their undergarment-facing side so that adhesive elements on one or more flaps can be secured. This feature provides users of the sanitary napkin product with the choice of employing side-protecting flaps upon demand or leaving them in place. The napkins also incorporate preferred adhesive element systems which can be disposed to contact silicone treated films or other release areas on their undergarment-facing sides. Additional embodiments of this invention provide for extending the release surface to enable tri-folding of the napkin and a partial or total elimination of traditionally required release paper strips.
