Abstract
A wc-disposable ostomy bag has an outer water soluble layer of polyvinyl alcohol and an inner relatively insoluble layer of polyvinylidene chloride. A flange of a double-sided pressure-sensitive adhesive ring has one side adhered to the outer layer only, around an opening into the bag so that the edge of the outer layer around the opening is left exposed to material passing through the opening. The other side of the flange in use is secured to the patient's skin around the stoma either directly or via a peristomal wafer.
