COMPOSITE SYSTEM PROVIDED WITH AN OXYGEN SCAVENGER/INDICATOR FUNCTION AND THE USE THEREOF

摘要

The invention relates to a composite system provided with an oxygen scavenger/indicator function comprising at least one type of metal which is used in the form of an oxygen sorption agent and whose oxidation degree can be increased by oxygen. The inventive composite system also provided with an activator. The indicator function is carried out by modifying the physic al properties of oxygen sorption agent which is effected by metal oxidation.
