The present invention relates to a microporous non-woven tape to be adhered to human skin by means of an adhesive layer harmless to the skin, providing the unique combination of both moisture-vapour permeability and hydrostatic-pressure resistance. Said tape may also be welded to a thermoplastic film. This product is highly suitable to be used as self-adhesive flange for stoma bags. The product comprises a porous, woven or non-woven web of paper, synthetic or natural fibers, to which an adhesive coating layer is applied and the product is coated and/or impregnated with a thermoplastic material and surfactant in such a way that it has a moisture vapour transmission rate independent of the direction of at least 150 g/m<2>/24h at 37 DEG C and at the same time is withstanding a hydrostatic column of a 0.9% NaCl/H2O solution of 11.5 cm height for at least 20 seconds withour leakage, said product optionally being covered by a protective release liner. |
