Improved active oxygen scavenging packaging articles optionally further comprising SiO and/or EAA coatings are disclosed. Also improved active oxygen scavenging copolycondensates and their use in packaging articles are disclosed. Specifically disclosed are (1) the use of an oxidation moderator or controller (anti-oxidant) along with the copolycondensate scavenger and (2) post polymerization treatment of the copolycondensate substantially in the absence of oxygen. The improvements lead to increased oxygen consumption by the active oxygen scavenger and improved packaging characteristics for the active oxygen scavenging copolycondensates.
