Принадлежит: Performance Managing And Consulting Inc

A product and method for providing oxygen remediating extruded or other melt-phase plastics for packages for reducing oxygen-linked damage to foods, pharmaceuticals, or other oxygen sensitive substances. The method for making oxygen remediating melt-phase incorporated plastics for packages and packaging elements generally includes the addition of an oxygen managing combination of compounds that restrict the migration of oxygen and/or eliminate migration oxygen through reaction with components of the polymer additive. Dry components remain inactive until moisture from the packaged food partially deliquesces a formulary component to trigger oxidation of a powdered metal or other oxidizing compound. Other additives absorb and distribute moisture and facilitate electron movement for improved oxidation.
