POLYPROPYLENE-GRAFT-ACRYLIC ACID OR POLYPROPYLENE-GRAFT-MALEIC ANHYDRIDE IN OXYGEN SCAVENGINE TIE LAYERS

摘要

Multilayer packaging articles contain (i) an oxygen scavenging tie layer which includes polypropylene-graft-acrylic acid (PP-g-AA), polypropylene-graft-maleic anhydride (PP-g­MA), 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.
