Sachets were one of the first promising technologies for oxygen scavenging. Since the sachet is an applied packet, there is very little disruption to the package production line. Sachets are also fairly inexpensive in relation to the added value that they provide for the quality of the product. Because sachets are made in a variety in sizes, shapes, absorbency levels and forms, many different foods can be catered towards the specific bio-chemical needs of that food.

Oxygen scavenging film, on the other hand, is a more emerging packaging technology that, as described previously, contains the active material within the film of the package. The benefit to this technology is that the reactants can often be integrated within the various layers of the packaging — adhesive, printing ink, lacquer or enamel as done with cans (Rooney, Chapter 4).
