ABSTRACT:
A wc-disposable ostomy bag has walls made of three layers. The central layer is of an alkali-soluble/water-resistant material such as carboxylated acrylic polymer and is about 100.mu. thick. The inner layer, presented to the contents of the bag, is of a water-resistant, ordor-proof material such as polyvinylidene chloride and is between about 2 and 3.mu. thick. The outer layer is a non-woven material such as formed by cellulose fibres in a binder of aqueous polyacrylate, which is broken up when wetted by an alkaline liquid.
