The film backing sheet has two parts; a dressing and a bounding area heat sealed to the film carrier. The dressing area being defined by a cut line just inside the heat sealed area. The sandwich forms a contamination barrier package. The adhesive coating and siliconized release paper form a barrier on that side of the dressing and the film carrier and the heat seal form a barrier package. The adhesive is on the other side of the dressing. A part of the cut line is perforated to resist separation of the dressing during removal of the siliconized release paper. The manufacturing method includes the steps of; transferring the release paper and adhesive to the film backing sheet, cutting the film backing sheet to define the dressing, heat sealing the film carrier about the edges of the cut line of the dressing and severing individual dressings.
