DUNCAN, S.C. — The newest addition to the Cryovac Freshness Plus line of active packaging materials incorporates scavenging material into the barrier layer of film to yield superior oxygen protection, according to Sealed Air. The scavenging components, since they are in the film, may trap oxygen that may migrate slowly into the film from the package headspace or from the environment. Applications include fresh red meat, processed meats, cheeses, bakery products and fresh pasta.
The film does not require an activation step, which means it may be used with existing equipment. The scavenging material is invisible to metal detectors. Freshness Plus active barrier films do not require moisture to activate the scavenging reaction and are equally effective with wet or dry products.
"By extending our line of Freshness Plus active packaging technologies, we are addressing the market trends toward foods that are minimally processed, organically sourced, natural and are free of trans fats," said Scott Beckwith, new business development manager for Sealed Air’s Cryovac Food Packaging. "All of these trends can result in products that are more oxygen-sensitive."
