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.

Pattern coated adhesive article

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.

A process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls. Also, a process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; disposing a barrier film onto the dried adhesive; casting a liquid plastisol formulation onto the barrier film; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the barrier film; and, winding the resulting tape laminate onto rolls.

Process for manufacturing tape products

A water resistant, flexible, dermal adhesive product for conformable topical application to human skin, the dermal adhesive product comprising a backing sheet having an adhesive for removably adhering the sheet to the skin, wherein the adhesive is a highly crosslinked pressure sensitive adhesive composition comprising the polymerization reaction product of about 75% to about 95% of a mixture of at least two alkyl acrylate or methacrylate esters, about 1% to about 10% ethylenically unsaturated carboxylic acid, and about 10% to about 20% vinyl lactam, by dry weight of solids, preferably about 80% to about 90% of a mixture of at least two alkyl acrylate or methacrylate esters, about 2% to about 5% ethylenically unsaturated carboxylic acid, and about 10% to about 20% vinyl lactam, by dry weight of solids.
