Abstract: A linerless pressure-sensitive label uses a heat-activated, non-tacky dead coat to cover a pressure sensitive substratum. Upon heat activation, the dead coat melts and admixes with an underlying pressure-sensitive adhesive substratum thereby resulting in an exposed pressure-sensitive adhesive.

The elimination of the silicone-coated release liner results in lower material costs, lower shipping costs and less waste.
