what type of seal do these have in order to make them air tight?

I ordered them for loose leaf tea, but I would say they are definitely NOT air tight! For the price...they are decent containers, but I'm buying new containers for tea...one by one as I save for them! hope this helps!

There is no rubber seal or gasket, but the top screws on and appears to be very tight.

Mine was sealed in a plastic bag, but I can't say if it was air tight because I didn't stick it under water to test it. (shrug) Sorry I can't be of more help. I do know it works great in my Filter Queen defender.

I don't know if I would consider it "air tight" or "air proof" as the seal is a foam strip (not rubber or some denser material), but the latch does keep the lid snapped closed. I roll mine around a lot though and tend to grap it from the front, which then unsnaps the seal. Argh. I have to remember to grab with both hands on either side of the snap, and then it works fine. I like them. (I took a photo for you as I thought there was a way to upload photos ... but I can't see how to do that on this answer.)

Hi Chris, These doesn't have any seal just twist top. For the seal one you can purchase these ones: http://www.amazon.com/gp/product/B00CJWTN5U These tins have plastic/silicon kind seal in inside and it's water/air proof.

They have a pretty good rubber (maybe soft plastic) seal. I don'think it's air tight. They have been dependable in storing flour and cookies.

Yes, I purchased them for long term storage since they have an air tight seal.

Don't know for sure because I didn't do that, but my best guess would be that they would stay put, because the seal is really tight, and it really takes some effort just to slide it on.

My relative, who works in manufacturing of similar items, has told me that the airtight silicone seals are meant to stay in place. Apparently, higher temperatures can affect the effectiveness, and the silicone ring may start falling out of place. I would contact the manufacturer to see if they will send you a replacement, might be easier than returning to a merchant, especially if it has been some time. http://progressiveintl.com/contact

These vacuum sealers will seal almost anything. I regularly use cheap quart zip lock type freezer bags from the dollar store. I cut the zipper part off with scissors put a serving of food in, fold a pleat in the opening and vacuum and seal perfectly.

There is a thin rubber gasket around the lids, this makes the seal very secure. I have had the canisters for several months and have no problem.

They screw on and have a rubber gasket to seal them. But sometimes they get loose

I do not believe they are "air tight." If they were I think there would be a bit more resistance felt when closing and locking the box because of pressure on the O-ring. The manufacturer says that they are "water resistant." Were they "water-proof" then they would be airtight.

They stay sealed for a long time. I have used these many times and the seal stays with no problem.

These canisters do have a gel seal around the inside of the covers. As long as you keep them clean from the contents, the seal is airtight.

No they do not have a seal over the opening. I have been buying Biofreeze for years without a seal.

I use them for Limoncello, and they seem to seal pretty tight. I would say, yes they are air tight as they are placed on their sides with the liquid against the top and show no signs of leaks.
