This is a multi-ply pressure sensitive laminate consisting of a face stock, a layer of adhesive, a standard release liner, a layer of adhesive, and a standard release liner. This type of product provides a single label that can be applied to a substrate using the adhesive on the middle liner; then the top ply is removed and applied to a different substrate using the adhesive on the face stock.
When used to describe a self-adhesive laminate this means that there are muliple layers of face material, adhesive, and backing all combined to form a single laminate for production purposes.
A type of pressure sensitive label on a pressure sensitive liner. The double-ply label is carried on a standard release liner. Once the double-ply is applied to a substrate, the top ply can be removed and applied to yet another substrate.
