Are All Oxygen Absorbers the Same?

Not all oxygen absorbers are created equal, but most are going to have elements of sodium and small traces of iron. Some of these packets come with iron in the form of a powder, and others will have a material closer to steel wool.

Then you will have some of the iron-free options that will be made: ascorbic acids, activated carbon, types of sodium carbonates, and diatomaceous earth.

What Size Oxygen Absorbers Do You Need for Mylar Bags?

There will be different needs concerning the size of the mylar bag and what is being stored inside. However, as a general rule, three hundred CC absorbers will be for the most common size Mylar bags which will be around twenty-five cm by forty cm.

The largest sizes will need the two thousand cc-sized packets, which oxygen absorbers rarely come in sizes larger than this.

Smaller sizes will use the fifty cc sizes. Just know that there will be enough oxygen absorbers, whether individually or in combination with other packets, to cover the needs of any Mylar bag food storage projects.


How Do You Choose Which One You Need?

For the most part, the size of the Mylar bag and its contents are kept inside the packaging. However, as mentioned earlier in this article, certain cc sizes will fit the larger bags (two thousand ccs) and smaller bags (fifty ccs).

In addition to these elements, you will need to factor in any allergy sensitivity or ingredients chemically reacting together, such as iron and the oxidation process.

For example, some contents will not mix well with sodium or iron, or some of the other ingredients used to make the oxygen absorber packets.


How Do You Know If Your Oxygen Absorber is Good?

There will be a few checks that you can perform that will tell you if an oxygen absorber is working or ready to work inside the packaging itself.

If you are testing a package of these items, the best test will be to take a single packet and see if the oxygen absorber warms up in a timely fashion.

Otherwise, the only other way to test the effectiveness of these packets will be to see if there is any air in the vacuum-sealed Mylar bags, which can be tested with simple pressure or pinching.


Should Oxygen Absorbers be Hard or Soft?

If you have an Oxygen Absorber that is hard, then you have one that has been used and has likely been depleted completely. You will want to use a different packet or replace this absorber with a fresh one.

When you buy a brand-new package of oxygen absorbers, the packets should be soft enough so that you can feel the powder if you roll it between the index finger and thumb.

Like salt packets, you find at most sit-down restaurants, pinch one for comparison, and you will have a good idea of what an oxygen absorber packet should feel like.
