Abstract
An oriented multilayer structure for shrink applications having a polymeric layer, a tie layer adhered to said polymeric layer. The tie layer is made up of the reaction product of a live, grafted polyolefin and an olefin elastomer. The multilayer structure is oriented and the tie layer provides strong adhesion to barrier layers even at high orientation levels.
