2123003 9308777 PCTABS00021 A thin film wound dressing that is particularly easy to position accurately and apply smoothly to form an occlusive seal comprises three layers: a first wound covering layer (21) being permeable to gases and water vapor while being impermeable to microbes and liquids; a second adhesive layer (23) intimately disposed on the first layer for use in occlusively attaching the invention to skin or wound surfaces; and a third release backing layer (27) disposed on the second adhesive layer. The release backing layer has a functionally contiguous or integral pull-tab (25) attached in a manner that creates a substantially U-shaped release backing/pull-tab assembly. The release backing (27) and pull-tab portions (25) of the assembly are highly flexible while also being highly resistant to elongation.
