Composite system, used as packaging foil, bag foil or partially applied single foil, comprises substrate foil thin film and catalyst for reduction of oxygen

摘要

A composite system comprises at least a substrate foil, at least a thin film and at least a catalyst for the reduction of oxygen. An independent claim is included for the oxygen-free packing of oxidation-sensitive packaged goods, where the goods are packaged in a compartment, comprising inserting a composite system, rinsing with inert gas mixed reduced gas and sealing with gas density.
