PackFreshUSA Oxygen Absorber

Yes, these packets are food-grade and non-toxic. They are designed to be placed directly into your storage containers or Mylar bags alongside dry goods like grains, beans, and dehydrated foods.

The 2000cc capacity is designed for larger storage containers, such as 5-gallon buckets or large Mylar bags. If you are using smaller containers, you may want to opt for a lower-capacity packet to avoid wasting absorption power.

Yes, it is critical to keep unused packets in an airtight environment immediately after opening the original packaging. If they are left exposed to air, they will begin absorbing oxygen and lose their effectiveness before you even use them.

No, these oxygen absorbers are strictly for dry food storage. They are not designed for wet foods, liquids, or items with high moisture content, as this can cause the packets to fail or create an unsafe environment.

By creating an oxygen-free environment, these packets significantly slow down oxidation and prevent spoilage, which can extend the shelf life of dry goods by years. The exact duration depends on the type of food, the quality of your storage container, and the seal integrity.
