Abstract
A wound dressing is disclosed in which a pressure-sensitive adhesive layer, preferably of a soft, pliant adhesive composition having one or more hydrocolloids dispersed therein, is backed by an elastomeric film and has its opposite (bodyside) surface covered by a removable primary release sheet and a release strip, with at least a portion of the release strip being interposed between the adhesive layer and the primary release sheet along one side edge of the dressing. The primary release sheet and the release strip have superposed or overlapping tab portions that project outwardly beyond a side edge portion of the dressing. In a preferred embodiment, the adhesive and backing layers are translucent and the release strip is visible therethrough by reason of sharp color or tonal contrast in relation to the primary release sheet.
