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 can be used with existing equipment, because it does not require an activation step. The scavenging polymer is invisible to metal detectors, allowing processors to use metal detection systems after the product is packaged. Designed 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.
Cryovac: Cryovac: Barrier film with oxygen protection
