Abstract: Multilayer packaging articles contain (i) an oxygen scavenging tie layer which includes polypropylene-graft-acrylic acid (PP-g-AA), polypropylene-graft-maleic anhydride (PP-g-MA), or a mixture thereof; (ii) a second layer; and (iii) a third layer, wherein the oxygen scavenging-tie layer is located between the second layer and the third layer. In addition to the oxygen scavenging function, the oxygen scavenging tie layer functions as a tie layer to inhibit delamination of the second layer from the third layer, or vice versa.
