Consumables

Oxygen scavengers or Oxygen absorbers are added to enclosed packaging to help remove or decrease the level of oxygen in the package. They are used to help maintain product safety and extend shelf life.^[1] There are many types of oxygen absorbers available to cover a wide array of applications.^[2][3]

The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures.^[4] Others are part of a polymer structure.^[5]
