Q: How many would you need to use in a 5 gallon bucket for storing beens and rice and other such dry goods ?

A five gallon bucket contains 18,927.06 cc (ml) of volume. The listed size of the packet is the volume of oxygen that will be absorbed by the packet. But, remember oxygen is only about 1/5 the volume of air, so you don't need to absorb that full volume (if you did, you would need 9 2000ml packets), and your product would also take up volume, though that is trickier to measure. Not taking into account product volume, two 2000ml packs should more than absorb the 3880ml of oxygen in an empty bucket. One could assume that the product would replace half that volume (beans use less volume than rice, e.g.), but two should give a comfortable margin of safety in case they don't live up to specs anyway.

Q: Just received mine and there are no instructions or expiration date on them. How ling are they good for?

It IS a matter of date, because they have a short shelf life. Oxygen absorbers comes in two types, B and D. Type B is for food that has some moisture in it (like beef jerky) to activate the packet. They have a useful shelf life of about 1 year from manufacture if they are properly re-sealed after opening the original packaging. Type D is for dry foods (rice, beans, grain, pasta). They have their own source of moisture to facilitate activation, and they have a shelf life of about 6 months from manufacture even when properly re-sealed. Type B will not work for dry food applications because there is insufficient moisture to activate them. I know this from product literature and (sadly) personal experience. Unfortunately, this product is not labeled for type, so we don’t know if it will work for dry food application. Maybe the supplier can comment on type B or D.

Q: does the higher the cc level mean that they are stronger?and also do these things last forever or do they need to be replaced after so long?

The higher cc level means they can remove more oxygen from the sealed product. The larger the bag you are sealing, the more air can fill the spaces in between the food particles. There are some excellent resources on the internet which correlate bag size and proper cc’s to use to effectively remove the oxygen. If your product is sealed against air intrusion (Plastic still allows air to slowly seep in. You should be using Mylar or glass.) and you use the proper size for the job, once the oxygen is spent, the chemical reaction stops. If you introduce more air, you may need to add a new oxygen absorber.

Q: What are the dimensions for 50 cc in inches?

1 x 2 inches at most but these are 500cc packets not 50.

Amazon packaging needs work

The actual product is fine. It was Amazon’s packaging that was bad. As I picked it up to bring it in the house the product fell out of the package. The end of the envelope was completely unsealed

Simply Do Not Work

I ordered these twice thinking the first batch (in June) was just old or just a fluke. Ordered again in August and neither pak worked. Both paks went into the trash. YES, I knew to put them immediately into a mason jar with a lid after opening the package. I've used literally hundreds of O2 absorbers and never had a batch not work at all. Usually it takes only a few minutes after putting the opened pak into a jar for the jar to seal itself. These NEVER sealed. I put some into a mylar bag and again-- Nothing.MADE IN CHINA stamped on the front of the package. The individual paks are TEENY-TINY~ Don't buy.
