Methods of making oxygen scavenging articles containing moisture

摘要

An extruded or molded article containing iron based oxygen scavenger, electrolytes, activated carbon, silica gel, or other water absorbing media, and optionally pore formers, is subjected to deformation to create voids or porosity, and subjected to water spraying or dipping to obtain a water activity of 0.4 or higher. The article is placed in a container or package containing oxygen sensitive articles.
