A wc-disposable ostomy bag is made from an alkali-disposable sheet comprising an outer layer of a non-woven material, an inner, thin layer of an alkali-resistant material and an intermediate layer of an alkali-soluble material such as carboxylated acrylic polymer. The alkali-resistant material has a high odor barrier and may be of polyvinylidene chloride. The non-woven material comprises fibers retained with one another by a colored alkali-soluble binder sprayed onto the fibers to form discontinuous regions of binder. |
