I was wondering if you guys had an answer to this or could direct me to the answer: Those oxygen absorber packs that you get inside of food like beef jerky and medication / pill bottles. Can those be re-used for food storage, etc.?
Also, who would you recommend as suppliers for these?
There are two quite different types of packets. They usually have identifying markings. The two main types are:
1.) Most of the pill bottles and many electronics come packaged with a silica gel (moisture absorbing) packet and those CAN be gathered up and then re-dried in batches on a cookie sheet in a low oven (175 F) for 8 hours, and re-used. Once they are re-dried you should immediately seal them in Zip-Loc bags, or they will begin to absorb the ambient room moisture, if left out.
2.) The oxygen O2 absorbers found in some food packages use an iron oxide chemical reaction process that starts once they are exposed to oxygen. Those CANNOT be re-used. So just discard those.
O2 Absorbers are available in sealed bags from Readymade Resources. (One of our advertisers)
