Adhesive sheet
First Claim
1. An adhesive sheet material for use on the skin which comprises a film backing layer which has upon at least a portion of one surface thereof a pressure sensitive adhesive layer, a removable release liner covering the adhesive layer and a removable support layer attached to the surface of the backing layer remote from the pressure sensitive adhesive layer wherein the stripping load required to separate the release liner from the adhesive layer is at least 25% greater than the stripping load required to separate the support layer from the backing layer and the release liner is stiffer than the support layer.

Abstract
An adhesive sheet material for use comprises a backing layer which has upon at least a portion of one surface a pressure sensitive adhesive layer. A removable release liner covers the adhesive layer and a support layer is attached to the backing layer on the surface remote from the pressure sensitive adhesive layer. The stripping load required to separate the release liner from the adhesive layer is greater than the stripping load required to separate the support layer from the backing layer. As the release liner is stiffer than the support layer then the release liner can be removed from the adhesive without disturbing the support layer. The support layer is conformable enough to remain attached to the sheet when adhered to the skin. Adhesive sheets in the form of ostomy flanges and IV dressings are described.
