This invention is directed to a pressure sensitive positioning adhesive for absorbent articles which can be used without release paper. The positioning adhesive has non-tacky irregularly shaped particles on its surface thereby rendering the adhesive non-tacky. Upon the application of pressure during use, i.e., when attaching the napkin to the undergarment, the particles are rearranged, exposing adhesive to the undergarment, thereby facilitating attachment of the napkin to the undergarment.

Adhesive attachment system with a non-tacky surface for sanitary napkins

A surgical dressing consisting of a film which carries an adhesive layer wherein the film has a hydration rate of at least 0.1 g/in.sup.2 /min.; becomes saturated when in contact with water in 3 minutes or less and absorbs at least its own weight of water. The film comprises a polyethylene oxide and a polymer or polymers selected from an ether based polyurethane and a polyether block amide. The dressing finds special use as a IV catheter site cover.
