Adhesive composite dressings (10, 110, 210, 310) with delivery systems and methods of manufacturing the dressings are disclosed. The dressings (10, 110, 210, 310) include liners (16, 116, 216a and 216b, 316a and 316b) having a release surface (15, 215a and 215b, 315a and 315b) and a retention surface (19, 219a). The bond strength between the liner (16, 116, 216a and 216b, 316a and 316b) and the pressure sensitive adhesive (14, 114, 214, 314) in the area of the retention surface (19, 219a) is greater than the bond strength between the liner (16, 116, 216a and 216b, 316a and 316b) and the pressure sensitive adhesive (14, 114, 214, 314) in release surface (15, 215a and 215b, 315a and 315b). The increased bond strength in the area of the retention surface allows the backing (12, 112, 212, 312) to be held taut during delivery to assist in smooth aseptic delivery of the dressing (10, 110, 210, 310). The retention surfaces can be provided by abrasion, embossing, perforating the liner, or combinations thereof. |
