ABSTRACT:
A zipper mechanism is stitched to one side of a base which has a layer of adhesive on the other side. A release liner covers the adhesive and includes a plurality of rows of slits which define sections which are separated from each other. The zipper mechanism is attached to the base by rows of stitches with the rows of stitches being located between sections of the release liner so the release liner can be separated from an adhesive layer covering position in sections without interference by the stitching. The zipper mechanism is formed by a method which slits the release liner just prior to stitching the zipper mechanism to the base and locating each row of stitches between adjacent rows of slits defined in the release liner.
