Abstract
The invention relates to a adhesive article comprising at least one backing layer with a first and second surface and a pressure sensitive adhesive layer adhered first surface of the backing layer in a pattern, wherein the pattern of the adhesive layer has an adhesive free area of less than about 25% and wherein the adhesive article has a water vapor transmission rate of greater than about 2000 g/m /24 hour. The invention also relates to a method of forming an adhesive article comprising (a) providing a release liner, (b) applying pressure sensitive adhesive in a pattern wherein the free adhesive area is less than 25%, and (c) applying a backing layer to the pressure sensitive adhesive. The present invention provides pattern coated adhesive bandages that strongly adhere to human skin while permitting water vapor transmission there through. Accordingly the present invention also provides methods of facilitating the healing of wounds using the pattern coated adhesive bandage. High breathability, as measured by moisture vapor transmission rate (MVTR), is desirable features of an adhesive bandage in order to prevent maceration of the skin due to trapped moisture, and to enhance comfort during wear of the bandage by the end user.
