In addition, the oxygen absorber preserves packaged foods without additives or preservatives and also extends the shelf life and maintains the quality of perishable foods.

These 300cc oxygen absorbers will absorb 300 cubic centimeters of oxygen.

What is an oxygen absorber?

Oxygen Absorbing Packets (OAPs) chemically capture available oxygen from their surroundings. Because oxygen is bad for food, oxygen absorbers are very useful in keeping things fresh, especially for long-term food storage and commercial food packaging.
OAPs are also used in pharmaceuticals, birdseed and pet food, medicinal herbs, and the preservation of artwork and artifacts.

How does it work?

Oxygen absorbers are made of iron powder formulations that, when exposed to oxygen, change to iron oxide. This chemically removes oxygen from the environment at the molecular level.
It is similar to a sponge that absorbs oxygen until it’s full and must be kept sealed before use to ensure it absorbs its full capacity. They come in various sizes and are rated based on how much oxygen they can absorb.

How to use oxygen absorbers?

To use an oxygen absorber:
1. Put your food in the bag.
2. Include oxygen absorbers appropriate to the size of your bag.
3. When vacuum sealing, remove most of the air and leave a tiny amount in the bags rather than all of it. You want to seal the bag right before the vacuum sealer pulls the bag tight against the food. This prevents the bag from being pulled too tightly against the plastic and puncturing it.
