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 label can then be applied to packaging or an end product by pressing the adhesive side of the label to the packaging or end product similar to a conventional pressure-sensitive label, however, no silicone-coated release liner is required. The elimination of the silicone-coated release liner results in lower material costs, lower shipping costs and less waste.
