Want to put them in emergency kits (car, camp, pack, bug out bag) and want to know if they'll stay any fresher, or last longer if I vacuumed sealed?

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.

Vacuum sealing will not extend storage life as the cyalume chemical is already sealed in an air tight tube which prevents leakage and exposure to air. Temperature is a much more important factor. Heat will decrease their shelf life so I'd consider storing them in a cool place.

If you put it into individual jars with sealing lids, and store it in a cupboard out of the light it keeps well. This way each jar stays sealed up until till you need it. I've gone moths on a bag with very little loss of freshness. My sister had the same concern so she split a bag with another person.

No as long as you keep them sealed in a plastic bag they will last weeks. I dry mine out in the oven and then vacuum seal them in a container, although that is not necessary. They will last for a year if I need them too. I keep them in a zip lock bag on my dive trips and they last all week long. When you need one or two make sure you are in a low humidity area like an air conditioned hotel room when you open the baggie. Pull out what you need and reseal the bag. Hope this helps.

It depends on how you store them, and how much of a perfectionist you are. I vacuum seal them in quart mason jars as soon as I receive them, and store them in a low cool cabinet. They are fine for 6 months.

I'm not sure about the "best" way. Some recommend refrigerating, but I figured that wasn't needed until after the bag was opened, so that's what I do. They only last a month or so. Freezing is probably good for longer periods. I just store the new bags in the pantry.

From what I've read, the are good for about 2 years, but look at what the expiration printed on the cans you buy are (its depends on when they were canned). When I open the can, I put every thing I don't use then into small (serving size) zip lock bags, squeeze out the excess air, and put them in the freezer. These are really for an emergency, or a camping trip (most of the time when I open the can, it always gets used up pretty soon).Hope this helps.

I bought some at the end of last summer and again at Christmas time. My cats are still playing with them. Usually they will chew them before the can go stale. In regards to a bag... yes, they do come in an air sealed bag which you can continue to use for storage (once open no more vacuum seal). Your cat(s) will love these.

To keep them fresh, I put them in a large zip loc bag and kept them in the cupboard. They are dried so there is no need to refrigerate or anything like that. It took me about 3 months to use all of them up and they remained fresh during that time. I would think they could be used much longer as long you keep them in a sealed storage bag. They won't get moldy or spoiled.

I'd say awhile if you keep them sealed in a plastic bag. I had mine for about 2 weeks before our party-didn't open them and they were fresh and tasted good when we opened them.

As packaged they should last awile. If you open it to see what's in it, you might want to put it in the freezer. I'm extremely satisfied with my purchase and would recommend it to anyone.

They are dried and sealed... I have kept them in the bag sealed for a year without spoiling.... Once opened I keep on the shelf in the pantry - a dark cool place in a dry climate. If you have concerns put them in the fridg...

I don't know. I usually use mine within a month or so and they are fine. They are individually wrapped in a "vacuum" type package so I am guessing they have a long shelf life.

Theyre packed in salt, so like a couple months if you seal them up in a bag. They reak really bad tho, so i highly recommend putting them in a zip lock

They are freeze dried so should last indefinitely if sealed. If left open, moisture could get in and cause spoilage.

The bags that you don't use you should reseal in a bag or heat seal(I just put them in a freezer bag...) so they stay fresh. The ones you put in your safe you just drop in.

I have not detected any smell from them while in the original packaging and would not have a concern for having them in my pack while hiking. That said, I would use your descretion on how to store them while in camp. I always error on the side of caution if I have concern for visitors during e night.

They are not individually sealed, but each one stays fresh until you take it out of the opened package. In fact, I've kept an opened pack for nearly a year and they are still fresh.
