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 q<SUB>1</SUB>, q<SUB>2</SUB>, q<SUB>3</SUB>, q<SUB>4</SUB>, and r are independently selected from hydrogen, methyl, or ethyl; m is -(CH<SUB>2</SUB>)<SUB>n</SUB>-, wherein n is an integer from 0 to 4, inclusive, and, when r is hydrogen, at least one of q<SUB>1</SUB>, q<SUB>2</SUB>, q<SUB>3</SUB>, and q<SUB>4 </SUB>is 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.
