What is claimed is: 1. A laminated material for use in forming body wearable pouches in combination with at least one other pouch wall to define a body wearable pouch for collecting human body wastes, the laminated material comprising three distinct layers including a heat sealable fabric layer, a heat sealable odor barrier film layer and a separate thermoplastic adhesive layer therebetween, the adhesive layer being a hot melt thermoplastic adhesive that is substantially coextensive with facing surfaces of the fabric layer and the film layer so as to substantially continuously integrally bond the fabric layer to the film layer, said laminated material being neither soluble nor disintegratable in water, and wherein the thermoplastic adhesive layer has a thickness of approximately 1 mil, the film and adhesive layers have a total thickness of approximately 3½ mil, and the adhesive layer penetrates into the fabric layer. 2. The laminated material of claim 1 wherein the fabric layer is formed of natural or synthetic fibers, or blends thereof. 3. The laminated material of claim 2 wherein the fabric layer includes fibers formed of cotton, silk, or cellulosic materials. 4. The laminated material of claim 1 wherein the fabric layer includes fibers comprising nylon, polypropylene, polyester, low-density polyethylene, or a sheath of low-density polyethylene having a core disposed therein. 5. The laminated material of claim 4 wherein the core is formed of any one or more of polypropylene, polyester and nylon. 6. The laminated material of claim 1 wherein the fabric layer is brushed, sueded or sheared on at least one surface thereof. 7. The laminated material of claim 1 wherein the film layer is a monolithic film having both odor barrier and sealing properties. 8. The laminated material of claim 1 wherein the film layer is a multilayer film having at least an odor barrier sublayer and a sealing sublayer. 9. The laminated material of claim 8 wherein the odor barrier sublayer is formed of polyamide, polyvinyl alcohol, ethylene vinyl alcohol, or polyvinylidene chloride. 10. The laminated material of claim 8 wherein the sealing sublayer is formed of low-density polyethylene or a copolymer of low-density polyethylene. 11. A laminated material for use in forming body waste collection pouches in combination with at least one other pouch wall to define a body wearable pouch for collecting human body wastes, the laminated material comprising three distinct layers including a heat sealable fabric layer formed of fibers comprising nylon, polypropylene, polyester, low-density polyethylene, or a sheath of low-density polyethylene having a core disposed therein, a heat sealable odor barrier film layer comprising a multilayer film having at least an odor barrier sublayer and a sealing sublayer, and a separate thermoplastic adhesive layer therebetween, the adhesive layer being a hot melt thermoplastic adhesive that is substantially coextensive with facing surfaces of the fabric layer and the film layer so as to substantially continuously integrally bond the fabric layer to the film layer, said laminated material being neither soluble nor disintegratable in water, and wherein the thermoplastic adhesive layer has a thickness of approximately 1 mil, the film and adhesive layers have a total thickness of approximately 3½ mil, and the adhesive layer penetrates into the fabric layer. 12. The laminated material of claim 11 wherein the core is formed of any one or more of polypropylene, polyester and nylon. 13. The laminated material of claim 11 wherein the fabric layer is brushed, sueded or sheared on at least one surface thereof. 14. The laminated material of claim 11 wherein the odor barrier sublayer is formed of polyamide, polyvinyl alcohol, ethylene vinyl alcohol, or polyvinylidene chloride. 15. The laminated material of claim 11 wherein the sealing sublayer is formed of low-density polyethylene or a copolymer of low-density polyethylene. 16. A laminated material for use in forming ostomy pouches in combination with at least one other pouch wall to define a body wearable pouch for collecting human body wastes, the laminated material comprising: three distinct layers including a heat sealable fabric layer, a heat sealable odor barrier film layer, and a separate thermoplastic adhesive layer therebetween bonding the fabric layer to the film layer; the fabric layer being formed of fibers comprising nylon, polypropylene, polyester, low-density polyethylene, or a low-density polyethylene sheath having a core disposed therein; the film layer being a multilayer film having at least one odor barrier sublayer and at least one sealing sublayer, the odor barrier sublayer being formed of polyamide, polyvinyl alcohol, ethylene vinyl alcohol, or polyvinylidene chloride, and the sealing sublayer being formed of low-density polyethylene or a copolymer of low-density polyethylene; and the thermoplastic adhesive layer being a hot melt thermoplastic adhesive that is substantially coextensive with facing surfaces of the fabric layer and the film layer so as to substantially continuously integrally bond the fabric layer to the film layer, said laminated material being neither soluble nor disintegratable in water, and wherein the thermoplastic adhesive layer has a thickness of approximately 1 mil, the film and adhesive layers have a total thickness of approximately 3½ mil, and the adhesive layer penetrates into the fabric layer. 17. The laminated material of claim 16 wherein the film layer is a multilayer film having multiple odor barrier sublayers and at least one sealing sublayer to form a sealing side of the film layer.
