60-300cc Oxygen Absorbers (3 packs of 20ea.) for Vacuum Seal or Mylar Bag Food Storage,OF-300CC-60PK

Recieved, packeged nicely and actually Oxyfree brand. Easy to open but I didn’t realize there was a short lifetime when exposed to air by the time I was done packaging the first pack I opened were warm and soft. Lesson learned, could do with a caution statement.

Oxygen Absorbers are usually expensive and the quality is iffy at best. These are exceptionally well packaged, great price, and arrived quickly with great packaging. They work great, and we trust them with our food stores, highly recommended at this price, hard to beat!

Have not had any issues with this product. Oxygen absorbers absorb oxygen - air is 79% nitrogen, 21% oxygen. Not all bags will completely suck up especially things that have large gaps or are themselves full of air - CEREALS. If it doesn't fully suck in, IT DOESN'T MEAN IT DIDN'T WORK!I pre-seal my bags most of the way leaving small opening at the end to drop in absorbers. I work in small batches. I lay products somewhat flat and squeeze out additional air and seal. I work quickly and efficiently. I immediately put additional absorbers in a mason jar or vacuum seal them. I have used these absorbers with mylar bags and plastic food saver bags. I have now repurchased this product multiple times and had no issues.

FAST DEL., GREAT JOB !! WILL USE SELLER AGAIN !!ITEM WAS WHAT I WAS LOOKING FOR !!

I have used these Oxygen Absorbers for years with good results. The only problem is that you have to get those extra leftovers into an air tight storage container quickly or those you don't use will be no good the next time you need them. Organize your operation as best you can and count out how many OA's you need and put the extras in the sealed container. Then get those you are sealing put into their new home quickly. It works best to have a second pair of hands for this process. Unlike people OA's don't like fresh air.

I dehydrate garden harvest for wintertime cooking. Some things store better in mason jars than vacuum sealed packets, where vacuum-sealing would crush sliced cabbage or mushrooms (for example). The risk in dehydrating is moisture (and mold) getting into the jars. These are an excellent size for quart jars, or use two in half gallon jars. Anyone who's canned food knows there's a satisfying "hiss" when you break the pressure seal on a jar. So far, these have worked in every jar I've opened... and most of them keep doing the job if I don't use the full jar and just re-seal it. You do have to keep unused on locked tightly in a jar or vacuum sealed bag or they'll go bad before you use them. The price is excellent, far less expensive than what LDS canneries list these for.

Work great in bags and jars.

Great product !!!
