The newest addition to the Freshness Plus line of active packaging materials yields superior oxygen protection by incorporating scavenging material into the barrier layer of film. Because the scavenging polymer is built into the film, the scavenging components trap oxygen that can slowly migrate into the film from the package headspace or from the environment. The film does not require an activation step, and because the scavenging polymer is invisible to metal detectors, metal detection systems after packaging are not required. Ideal for oxygen sensitive products and products with a long shelf life, Freshness Plus active barrier films do not require moisture to activate the scavenging reaction and are equally effective with wet or dry products.
