Do I need a heat sealer for these bags?

Yes. Mylar bags are sealed with heat, either from a dedicated impulse sealer or a household iron on a low setting over a straight edge. Fold the top over and press firmly to get an airtight seam.

How much food does one 21 x 15 inch bag hold?

That size typically holds several pounds of rice, beans or flour, depending on the density of the food. It is meant for bulk staples rather than small portions.

How many oxygen absorbers go in each bag?

Match the absorber count to the volume of food and the absorber rating printed on the packet. Use too few and residual oxygen remains; use too many and you waste absorbers.

How long will food last in these bags?

Dry staples sealed with an oxygen absorber in Mylar commonly keep for many years, often cited as 10 to 25 years depending on the food and storage conditions. Keep the sealed bags cool and dry.

Are these bags reusable?

No. Once cut open and the seal is broken, the bag and its absorber are spent. Transfer the food to a new bag with a fresh absorber if you want to store it again.

Our take on the My Patriot Supply Mylar Bags with Oxygen Absorbers

These are food-grade Mylar storage bags sold by My Patriot Supply, a survival and emergency-preparedness brand, bundled with oxygen absorbers for long-term dry food storage. The bags measure 21 by 15 inches, making them large enough for bulk grains, rice, beans or flour, and they are made in the United States. The oxygen absorbers remove residual oxygen so sealed dry goods keep far longer than in jars or plain bags. Pricing varies by pack size and store, so compare the per-bag cost across listings before buying.
