Claim:
A method of making a packaged dressing, the dressing having a width, an extent and a perimeter, the dressing comprising a skin adhering side having an affixation adhesive thereon, and a back side opposite the skin adhering side, the dressing further comprising a first terminus at one end of the extent and a second terminus at the other end of the extent, the second terminus defining an opening end for the packaged dressing, the method comprising: A) coating a first surface of a cover material with a detachable high tack, pressure sensitive adhesive in a predetermined pattern on the surface of the cover material such that (i) the first surface of the cover material includes at least one tackless area which is devoid of adhesive and disposed to correspond to and encompass at least a substantial portion of an edge of the first terminus and at least a portion of the surface of the cover material just beyond the edge of first terminus, (ii) the high tack, pressure sensitive adhesive forms at least a closed shape that encompasses within it both the tackless area and a dressing receiving area, and (iii) the high tack, pressure sensitive adhesive is disposed to affix the back side of the dressing to the first surface of the cover material along the extent of the dressing except for the tackless area when the back side of the dressing is brought into contact with the high tack, pressure sensitive adhesive on the first surface of the cover material, B) forming a release island on a first surface of a backing material, the release island having a size and shape corresponding to the width, extent and perimeter of the dressing; C) sandwiching the dressing between the first surface of the cover material and the first surface of the backing material such that (i) the skin adhering side of the dressing will be in contact with and substantially correspond to the release island, (ii) substantially all of the extent of the back side of the dressing will be in contact with, and held by, the high tack, pressure sensitive adhesive on the first surface of the cover material, (iii) a substantial portion of the edge of the first terminus of the back side of the dressing overlays the tackless area on the cover and defines an application end for the dressing, and (iv) the closed shape of high tack, pressure sensitive adhesive forms a hermetic seal about the dressing encompassing at least the entire perimeter of the dressing and the tackless area on the first surface of the cover material.
