ABSTRACT:
Herein is disclosed multilayer packaging articles comprising an oxygen barrier layer comprising ethylene/vinyl alcohol copolymer (EVOH) (an “EVOH oxygen barrier layer”); an oxygen scavenging layer adjacent thereto, wherein the oxygen scavenging layer comprises a polymer comprising an ethylenic backbone and a cycloalkenyl group having structure I:wherein q1, q2, q3, q4, and r are independently selected from hydrogen, methyl, or ethyl; m is —(CH2)n—, wherein n is an integer from 0 to 4, inclusive, and, when r is hydrogen, at least one of q1, q2, q3, and q4is also hydrogen; and a third layer adjacent to the oxygen scavenging layer. In addition to the oxygen scavenging function, the oxygen scavenging layer functions as a tie layer to substantially inhibit delamination of the EVOH oxygen barrier layer from the third layer of the packaging article.
