摘要：
Methods of initiating oxygen scavenging are disclosed herein that rely on heat triggering. An oxygen scavenging composition that comprises an oxidizable organic compound and a transition metal catalyst is heated to an extent sufficient to initiate oxygen scavenging. Heat triggering can take place during the manufacture of a film or a packaging article from an oxygen scavenging composition, or it can take place after the film or packaging article has been manufactured.
