How tight is the seal? What if they are jostled around, will the seal open?

The seal didn't open when I used and I was in some rough terrain. Guess all depends on your activity

The bags I have stay sealed. What I do is put stuff in the bag, seal it then turn it upside down and shake it. They haven't opened yet. Hope this helps.

Seal is relatively tight but bags are basically baggies made from thicker plasic.

We have used the bag to protect our swimming pool control unit and have never had bag open or leak. Our grandchildren have not been able to get bag open either.

I can't guarantee, but it has a great seal, just have to follow the instructions so closely so not to cause leaks. It would be very challenging to get the walking boot through the narrow opening.

Yes, the seal is very thin and will not compress when the lid is screwed on. It is a novelty item only. I think it would be the luck of the draw if you got one that didn't leak.

The lid seals very tightly. You just have to muscle it open. It pops straight up.

Hi. The door seals tight, but there is a convenient chimney hole in the top center, about 1 inch diameter, where I always run my temp probe wire. Works great.

I have had no problem with the seal. I pressed the seal together so hard that my fingers hurt and I also went back and forth with the white closure 4 or 5 times before I used the vacuum on it. All of my seals have held and it has been over a month now and none have opened up. I think that you have to make sure the two zipper seals are tightly together before using the vacuum. Good luck, I hope this helps.

Mine are doing well after about a dozen uses. My only issue is getting gunk out of where it seals.

Maybe, but it would probably be really difficult to open if you put it that tight, you'd probably do better with a new fridge seal if you are trying.

I have never had a problem with the seal. Although you don't have that little bump you have in other jars, this one is just a matter of trust. I tighten the lid really good. When I make jam and after I put the lid on, I just tighten the lid, turn the jar upside down (Inversion) and set for 5 minutes. Turn over and it is sealed. Now remember the jam is hot and would seal as would a ball lid on a jelly jar. Are you putting in a cold liquid or hot liquid? Cold may make a difference.

No not really. They might longer than a reg container if you had them wrapped/packed inside something thermal or insulated. Also, the lid shuts tight but if you were to fill it with water, for example, I'm sure it would leak out. It's not a complete "seal".

Yes, the seal is not tight on these containers. Unfortunately, they leak as well.

It has to snap in place otherwise it will spew out. You need it to make the seal.

I would say it is not normal. Ours has been around for over a year now and the seal has always and still does work.

for a short time, not for serious freezing, the seal is good but not airtight

No only when the cholds mouth is pressing the seal open... very easy for them to do....

No! I believe it is likely to build up too much pressure if sealed. I do think the gasket keeps food moist but the side clips are in the way.

Mine stayed closed so well I had to loosen it a bit so I could flip it open easier. You should have no problems. (:
