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.
A laminate comprising: (a) a water-disintegratable film having a thickness of between about 30 and 80 microns, and selected from the group consisting of polyvinyl alcohol and polyethylene oxide, (b) a coextruded film of at least two layers, adhered to a first surface of the water-disintegratable film, comprising: (i) an oxygen impermeable layer having a thickness of between about 4 and 15 microns and selected from the group consisting of ethylene vinyl alcohol copolymer, vinylidene chloride polymer, and vinylidene chloride copolymer, and (ii) a melt-bond...
