We all know what a label is, but do you know how a label is made up? It may be more complex than you think. There are four main (layers) components which make up a self-adhesive label. The top layer is comprised of the label material itself this is normally a paper or synthetic material. On the underside is a adhesive which adheres to the packaging the label is to be applied. The bottom layer is the backing material which carries the label through the print process before being applied to the product, a release coating is added to the backing material to aid with the removal of the label in preparation for the application process.
