A skin covering material, e.g. for covering wounds, burns and the like, to protect them during the healing process, includes a tacky polymer complex layer (24) for adhesively contacting the skin, and a water vapour-permeable backing layer (22, 26) carrying the polymer. The polymer complex is produced by mixing together solutions of two hydrophilic polymers which are coprecipitatable, when mixed together, to form a water-insoluble complex. An example of a pair of such polymers is polyacrylic acid and polyethylene oxide. The assembly is suitably packaged in a sealed pouch (13) with high barrier properties towards water vapour and containing an atmosphere of high humidity. |
