ABSTRACT:
The adhesive bonding strength of a pressure sensitive adhesive on a laminate is selectively modified by applying a discontinuous layer of a non-adhesive material to the pressure sensitive adhesive. Preferably, the laminate is a preformed, label stock, including a label or substrate having a pressure sensitive adhesive on one surface thereof and a release sheet overlying the adhesive. The label is first delaminated from the release sheet to expose the oppositely facing surface of the label and the release sheet. A discontinuous layer of the non-adhesive material is then printed on either the release sheet or the adhesive. The release sheet is relaminated back onto the label to form a modified laminate with new adhesive properties. When the label is then separated from the release layer, the non-adhesive material adheres to the pressure sensitive adhesive to reduce the exposed surface area of the adhesive.
