Zusammenfassung: | Heat shrinkable labels formed of a polyolefin such as polypropylene have a permanent acrylic pressure sensitive adhesive on one surface thereof, and may be mounted on a release coated backing strip. A metallization layer and open style graphics may be applied to the labels, and the graphics may be protected by varnish or a second layer of heat shrinkable polyolefin material. The label has low shrink-back properties under high ambient temperature storage conditions, following application to a product, of less than three percent. |
