<p>A material 10 for the manufacture of an ostomy pouch includes a plurality of layers. A degradable layer 12 is sandwiched between a first, inner layer 14 and a second, outer layer 16, wherein at least a portion of the second, outer layer is separable from the degradable layer to expose at least part of the degradable layer to a degrader. In use, the material is inhibited from degradation until the degradable layer is exposed. The degradable layer may be attached to each of the inner and outer layers by a water-soluble adhesive 18a, 18b. Preferably, the inner and outer layers are extruded films of polylactic acid, whilst the degradable layer can be a polyvinyl alcohol film. The degradable layer may be water-soluble or compostable. Typically, at least one of the layers of the material includes an antibacterial agent. An ostomy pouch manufactured from the material is also claimed.</p> |
