ABSTRACT:
A method of making an absorbent product in which pressure sensitive adhesive is used to attach the product to a user's undergarment. The product does not require release paper to protect the adhesive from unintended contact prior to use. The product is made by forming depressions in a fluid impervious barrier so as to create raised areas in the barrier that protect the adhesive. The depressions may be formed in the garment facing surface of the barrier and the adhesive applied within the depressions so that the raised areas adjacent the depressions protect the adhesive. Alternatively, the depressions may be formed in the surface of the barrier opposite the garment facing surface so as to create raised areas in the garment facing surface and the adhesive applied adjacent the raised areas.
