November 18, 2008

An insulating label stock was patented. It comprises a thermal insulating layer with a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m2·K/W) and a first surface. A heat shrinkable face material is laminated directly to the first surface of the thermal insulating layer to form the label stock, which has a thickness of at least 0.0075 inches (0.0190 cm). The thermal insulating layer comprises polyethylene, polypropylene, or polyester in the form of fiber, fiberfill batt, foam, knit fabric, woven material or fleece material.
