Do all the O2 absorbers have to be used at once or are the individually sealed?

No you don't use them all at once, just reseal the bag the absorbers come it with a hair iron or regular iron. Just be careful when you cut the package to access the absorbers because you want to leave enough room to reseal.

The cubes are individually wrapped in foil, so you only need to open one at a time.I have not left any out because there really isn't a need to unwrap all of them at once. I have had some where the foil is partially punctured and the cubes are exposed to air for a couple of monthsand have not had any problems using them.

Not very well. Many times I have had to double seal them and even then there are occasions when air still gets in

They certainly seem to be completely sealed. Either using the snap on, one time use lid or the more expensive gamma lid. I prefer the gamma so that access is available to the product stored with out the hassle of replacing the snap on lid.

No, you don't have to use it all at once. And you CAN use one can over the course of multiple nights. I go through ONE butane canister every few weeks sometimes...assuming that I am outside for 1 or 2 hours a time. Short answer, you CAN turn it on and off to save the butane.

They are sealed units -- technical they should stay like that for ever. I buy them once in several months, and seem to work fine.

Correct, The food goes directly in the bag. Place oxygen absorber in the top and leave as little room at the top of the bag as possible then seal it.

When you buy the Oxy-Sorbs, they are packed in an air tight bag, once the bag is opened, you must put them into an absolutely airtight container, right away, they begin to absorb oxygen at once when exposed to air. left out in the open air, they will exaust themselves in about 20 to 25 minutes You will need an airtight container to put the un-used ones into as soon as you open them, you may use 1 Qt. canning jars with new lids, the lids will pull down and seal real quick, they will exaust the oxygen very quickly, but they simply must be put into an airtight container to work. A 500CC Oxy-Sorb will seal a one gallon jug of food such as rice, oatmeal, flour, cornmeal, etc. Just be sure to protect the un-used one in an airtight container as soon as you open the airtight bag they are shipped in, Floyd Fluf, Granbury Texas

In 6-pack, YES, wrapped and sealed individually; don't get 2-pack so don't know about it---I seem to remember long ago when buying 2-packs in home improvement stores, the two were wrapped together---no problem there; just throw a dryer sheet in with opened (unused) filter and if want, seal up with tape--but during our summers in North GA---we change filters every 2 months---so no sense for storing for so little time. We just changed the filter last week, they CAN last up to 3 months (2600 sq ft house-one level) but with pollen sky high, we change more often......have a clear, filtered Spring and Summer!

Yes the oxygen absorbers come in 3 vacuum packed bags. Be sure to put any unused absorbers in an air tight container. I use a Mason jar so I can take out as many as I need and reseal the rest.

they have sealers, but i just use an iron. place bag in bucket and fill , leaving enough room to seal, about 4-5 in. place a wooden dowel under bag, and seal from BOTH ends leaving a small opening to put in the oxygen absorbers. push out remaining air and finish sealing. the bags will end up looking as if there is no air in bag.

The package that the oxygen absorbers come in is airtight.Each packet is not.I use my food saver with a jar attachment to put all i did not use in a mason jar and remove the air this way each time you use them they are fresh.I also put a silica jell pack into the jar as extra protections.Before i did this i used a zip lock bag or a jar with lid ,the indicator changed in about 2 months whereas the vacuum packed jars i have almost a year and the indicator is unchanged.

The ones that I received seem to be fine; I've used several and they all have sealed.

When I opened my bag I immediately transferred them to a ziplock baggy. I don't think opening the bag to get one out will ruin them, but I wouldn't leave them out for long periods of time. Not the same as a oxygen absorber, these absorb moisture. I use them in my underwater housing for my camera for extra protection.

The three packs come individually sealed and then the three packs are sealed/wrapped together. They don't have a best use by date that I can see. If you don't open the pack it should last a few years. If opened, you better use or store in a ziplock to delay evaporation. The website was unhelpful with this question, but you could call their question/comment line 1-800-208-8738

The absorbers come in 3 sealed bags of 20 each. I don't know how to tell if they are expired other than they don't work. After 8 or 9 days of dragging all the stuff out sealing bags waiting a day then cutting open then resealing I ended up with about 10 sealed correctly. I had good flat seals on them all so it wasn't user error. I even started putting 2 and 3 absorbers in a bag but no luck. I might have just got a bad batch who knows. I bought a food sealer and stored what I wanted then put them in gray 5 gallon buckets. Alot less hassle with the same outcome. Hope this helps

The sticks come in sealed individual packets. Further sealing is not necessary. The bigger concern is keeping weight/pressure off the sticks that could compromise the separation of chemistry and cause premature activation.
