Oxygen Absorbers are a handy way of increasing shelf-life of
packaged food & pharmaceutical products. As the name suggests an "Oxygen
Absorber" work on the principle of removing oxygen gas from controlled packaging
environment. Lowered levels of oxygen directly improve the shelf-life of
packaged food products stored at room temperature. In pharmaceutical, nutraceutical and other
packaged drug industry, lowered levels of oxygen means drugs that are normally
prone to oxidative degradation will remain stable for a long period of time.

Oxygen absorber packets employs chemical reaction between ferrous
powder and oxygen gas to create ferric oxide. A strong affinity for oxygen, and
low reactivity to other gasses, makes elemental Iron most suitable for such
application. By this means oxygen gas can indefinitely be reduce to relatively
low levels in packaged goods. The Ferric powder and other constitutes like
salts and chelates that support the reduction process are encased in a poly
pouch which allows for gas exchange to take place. Such pouch has capacity to
remove oxygen, throughout the shelf-life of the packaged product, as long as,
there is ferrous powder readily available for oxidation.
