Methods and compositions for improved initiation of oxygen scavenging

摘要

An improved method of initiating oxygen scavenging by compositions which comprise compounding oxidizable organic compounds and transition metal catalysts to form a composition suitable for forming into films or articles for packaging of oxygen sensitive products is disclosed. The method requires the addition of small amounts of a base to the oxygen scavenging composition as it is being compounded to improve the initiation properties and subjecting the film or article formed from the composition to actinic or electron beam radiation.
