ABSTRACT:
The present invention provides a process for producing a wound dressing delivery system. The wound dressing delivery system is formed by extruding first and second thermoplastic resins onto the surface of a carrier sheet to form first and second thermoplastic films; the first thermoplastic film functions as a temporary support for the second thermoplastic film and the second thermoplastic film functions as a wound dressing and has a moisture vapor transmission rate of greater than 300 grams/square meter/24 hours (ASTM E-96:37.8.degree. C./90% R.H.). The first thermpolastic resin is extruded onto the surface of the carrier sheet and the second thermoplastic resin is extruded onto the surface of the first thermoplastic film such that the first thermoplastic film is interposed between the carrier sheet and the second thermoplastic film.
