Oxygen absorbers absorb oxygen through a chemical reaction. The sachet contains iron powder that reacts with the oxygen in the atmosphere, causing the iron to rust and form iron oxide, creating a nitrogen environment for long-term food storage. They protect dry foods from insect damage and help preserve product quality. They are used when dry foods are packaged in sealed containers. When used with proper packaging and sealing, the oxygen in the packaging is greatly reduced. Our absorbers bring the oxygen level down reliably to .01% or less.
How Oxygen Absorbers Work?
When an oxygen absorber is removed from its protective packaging, the moisture in the surrounding atmosphere begins to mingle with the iron particles inside of the Oxygen Absorber sachet. As the oxygen molecules from the moisture interact with the iron (Fe) particles, rust begins to develop. Typically, there must be at least 65% relative humidity in the surrounding atmosphere before the rusting process can begin. To remedy this dilemma, sodium is added to the mixture. The sodium acts as a catalyst, or activator, causing the iron powder to rust even with low relative humidity. With the conversion of iron and oxygen into a single iron oxide substance, the presence of oxygen in the surrounding atmosphere is dramatically reduced.The performance of oxygen absorbers is affected by the ambient temperature and relative
