PRESSURE-SENSITIVE ADHESIVE FILM ARTICLE HAVING A HIGH MOISTURE VAPOR TRANSMISSION Abstract A dressing having a continuous film of pressure-sensitive adhesive is described which film has dispersed therein a discontinous gaseous phase contained within voids in the adhesive and a high moisture vapor transmission such that the adhesive is useful as a dressing for moist healing of wounded skin without skin maceration. The cellular structure of the adhesive film provides microreserviors in the adhesive which provide mechanical cushioning of a wound covered by the adhesive film, and in conjunction with the hydrophilicity of the adhesive, allow for the controlled transmission of moisture through the adhesive and absorbence of moisture by the adhesive. This controlled transmission of moisture allows for amounts of moisture at the site of the wound that are optimal in moist healing therapy. In a preferred embodiment, the pressure-sensitive adhesive is present as a film in contact with a sheet also having a high moisture vapor transmission. A method of preparing the pressure-sensitive adhesive film article is also described.
