Abstract:
An adhesive composite comprisinga) a polymeric backing layer,b) a high moisture vapor transmission layer, andc) a skin contacting adhesive layer; wherein said high moisture vapor transmission layer is a polymeric film backing material that has a moisture vapor transmission rate of at least 2000 g/m.sup.2 /24 hrs/37.degree. C./100-20% RH when one mil thick as tested using the Upright Cup method and said high moisture vapor transmission layer is aqueous fluid and bacteria impermeable, and the polymeric backing layer is a polymeric film backing material having tensile strength when wet that is no more than 30% less than the tensile strength of the backing material when dry when one mil thick, provided that the material of layer a) is not the same as the material of layer b); and that the overall adhesive composite exhibits a moisture vapor transmission rate of at least about 1200 g/m.sup.2 /24 hrs/37.degree. C./100-20% RH.
