Title: Combination pouch and release sheet and method for producing same

Abstract: An improved release sheet for use in connection with a sanitary catamenial pad is disclosed. The improved release sheet exhibits superior noise, drape, bulk and gloss characteristics due to its method of production. A polyethylenic release material containing silicone capable of being fixed within the surface of the release material is coextruded with at least a base film to provide a film which is also embossed to provide a combination pouch and release sheet with superior physical characteristics. Corona treatment of the release material layer preferably occurs following embossing, but can occur prior to embossing or both prior to and following embossing to fix the silicone within the surface of the release material. In-line recycling of materials provides additional cost advantages.
