Abstract
Abstract A pressure sensitive label assembly includes labels mounted on a backing sheet with the labels having a pressure sensitive adhesive which includes between 45 wt. and 85 wt. % of a copolymer of propylene or ethylene with an aliphatic hydrocarbon having an open chain configuration with between 5 and 7, preferably 6, carbon atoms. The copolymer is preferably amorphous propylene-hexene. The pressure sensitive adhesive also includes liquid and solid tackifiers, and may include U.V. stabilizing and anti-oxidant material.
