<p>An ostomy pouch may have each of its walls made from a laminate of a) a soft, opaque, flexible, heat or RF weldable plastics film not more than 80 microns thick, b) an adhesive, c) a vapour-deposited metal or glass layer not exceeding 0.15 microns in thickness, and d) a thin coating layer, e.g. a lacquer. A method of making a film laminate for use as an ostomy pouch wall comprises laminating together a plurality of layers, one of which is a plastics film, e.g. 70 microns thick, vapour-depositing a thin metal or glass layer on a smooth polymer film, joining the said plurality of layers to the metal or glass layer, removing the smooth polymer film and replacing it by a further laminate of a plurality of layers of which at least one is a plastics film.</p> |
