Effect

For the purpose of this discussion, the term 'anitoxidant; is used to describe all stabilizer classes that are utilized to protect organic substrates from thermal and thermo-oxidative degradation during storage, processing or conversion and service life in the absence of ulttraviolet light (sunlight) and maintain its initial properties  (e.gmolecular architecture, appearance and organo-lephtic properties).

The effect of antioxidants is essentially a bulk effect although,during service life, degradation will start where the organic substrate contacts the environment (oxygen diffusion)

Antioxidant can be considered as typical multipurpose film stabilization, e.g BOPP film bouble bubble and cast film. In the BOPP tenter process, organic substrates with high molecular weight are used, requiring a betterstabilization package.
