Abstract

A wound dressing product is described which includes a flexible backing member that can be vacuum formed to include a depression. A pressure-sensitive adhesive layer extends across the depression side of the flexible backing member. A hydrogel material is positioned in the depression of the flexible backing member and a release liner extends over the exposed pressure-sensitive adhesive layer and the exposed hydrogel material, which release liner has a selective releasability whereby it can be removed from the wound dressing product intact, leaving a portion of the pressure-sensitive adhesive and the hydrogel material exposed.
