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.

They seal tight! I have two little boys- one in particular finds every loophole and he hasn't succeeded in opening these.

No, not a tight seal. I've not turned it upside down, but if I were to fill it with water and turned it upside down there would be a slight trickle.

I would say this container is not an air tight suction type seal. In fact, that is the thing i like least about this container. The sealing mechanism is weak and i am always worried it will open, especially when carried.

No problem as long as the complete mouth fits into the slot that enables the vacuum to be pulled. It seals fast and secure.

I have driven with them on their sides on my roof basket. They did not leak. Not extensive testing, but it seems like a good solid 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.

No, it's not a tight seal. Usually I can push it down far enough that it kind of wedges closed but there's no seal on it. Probably the only thing I don't like about it.

No, it is quite a tight seal as long as it is closed all the way. This may vary bottle to bottle but for the most part it works great.

Yes they should since they seal when you close them, and the seal is pretty strong.

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.

It seals up nicely so I do not think they would be able to escape. My dogs are 23 and 15 pounds they fit fine, they do not like it though, so mine sits and collects dust. I am sorry, I cannot remember if the box said what it was as I got mine a bit ago. To be safe you could order it as a gift and have it wrapped.

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".

Not a peep. Even at high speeds and in high winds. The edge is compressed pretty well all the way around so air and water don't compromise the seal.

Very easy to open, yes, but still tight enough of a seal that product will not spill out.

the seal on this tight. there is a rubber around the tight fitting lid that clamps down extra hard.

Agree that it is a tight seal, but may not be the best container if you are going to regularly use it to transport more "liquidy" foods like yogurt. Also, while its still tight, our lids have gotten a bit more loose over time.
