The composite has a backing coated with adhesive on at least a portion of the backing and a liner over the adhesive. At least one edge of the backing is a delivery strip which is separable from the remainder of the backing. The liner is securely adhered to the delivery strip and releaseably adhered to the remainder of the adhesive coated backing. The bond between the liner and the delivery strip is strong enough that the delivery strip will separate from the remainder of the backing before it will separate from the liner. | |
