Frequently Asked Questions


Q - What is mylar?
A - "Mylar" is a trade name for BoPET (Biaxially-oriented polyethylene terephthalatea). Mylar or
BoPET is simply a polyester film material that looks like foil.


Q - What are mylar bags used for?
A - Mylar bags are used to protect food against oxidation and aroma loss, achieving long shelf life.


Q - Is a thicker mylar bag like 5mil or 7mil better for food storage?

A - No. We have found that a 4mil mylar bag achieves a 0% OTR (oxygen transpiration rate). A thicker bag does not keep anymore air from getting in or out of a properly sealed bag.


Q - Why are oxygen absorbers used in mylar bags?
A - An oxygen absorber is used in mylar bags to prolong the shelf life. They prevent food color change,
stop oils in foods from becoming rancid, and also retard the growth of oxygen-using aerobic
microorganisms such as fungi.




Q- What does an oxygen absorber do?

A - Oxygen Absorbers designed to remove unwanted oxygen inside a packaged environment. 


Q - Why is removing oxygen important for food storage?

A - Removing the oxygen protects dry food from developing insects or growing mold or fungi. 


Q - Are Oxygen Absorbers safe to use with food?

A - Oxygen absorbers are safe and easy to use with food products such as dried
meats, baked goods, dried spices, bulk foods and other foodstuffs. Use inside a mylar bag or foil pouch to preserve the food for
long term food storage.


Q - How do I know if my oxygen absorber are good?

A - If the pack they are in is still vacuum sealed and the indicator inside is still pink. This means no oxygen has been able to infiltrate the bag and the absorbers are still at full capacity.


Q - How long do I have until the oxygen absorbers go bad?

A - Once exposed to air the sachets will start to absorber oxygen. You generally have apx 30 minutes before the oxygen absorbers have reached full capacity.


Q - What is I don't use all the oxygen absorbers in the package at one time?

A - You can put the remaining absorbers in something air tight like a mason jar or another vacuum sealed bag to use later. Just make sure to immediately pull them out after opening the package and re-seal them.


Q - Can I re-use an oxygen absorber?

A - No, an oxygen absorber can only be used once.


Q - All the air did not get removed from my bag. Does this mean the oxygen absorber didn't work?

A - An oxygen absorber only removes the oxygen from the air inside the bag. Oxygen only makes up 20% of our air so really only 20% of the air inside the bag will be absorbed. Sometimes this might be seen by the bag shrinking around the food.
