Abstract
Laminated sheet material 9 comprises a laminate of a polyvinyl alcohol or other water-disintegratable film 12 with a thin coextruded film comprising a melt-bondable layer 15 and an impermeable layer 14. The laminate is odor impermeable but water disposable and so can be used to form a toilet-disposable ostomy bag by melt-sealing around the edges 10 between the facing melt-sealable surfaces 15.
