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 didn't have any problem with the seal, but I don't know what exactly you are referring to. The seal was in good shape when I opened the top, and it came off without much effort. I hope that helps! David

I'm not sure, as I've never tried it. They do seal well without much effort on your part though.

Sometimes I have this problem if I don't completely release all of the pressure. If that doesn't work, use a little oil and run it as close to the seal as possible.

Not at all...it's actually quite tight and requires a bit of a tug when opening to fill.

I have only had them for a short while, but so far so good. A friend of mine has had them for much longer, and I have never heard her mention problems with leaks. She seems very happy with them. The seal seems pretty tight.

Yes, it snaps on to form somewhat of a seal, might have to try a little more pressure

The person would have to be able to hold the container and push the button to open the seal at the same time. The push button requires a fair amount of pressure and it would have to be coordinated with raising the container to the lips.

It seems to seal tight on the one I got but it has it's own casing that u can remove and place in its own compartment inside the container ... Hope this helps :)

The seal is pretty tight so probably not - never had any problems like that as we live in Florida

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.

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.

Sometimes the seal can be a bit loose. Once it came off and stuck to the plastic lid. Have you looked inside to check?

it does appear tight...just make sure you click the lid shut :) thats been my only concern if i forgot to

The opening is not large, if you can work it over the tether without tearing it it will work fine for a short period of time. The seal area is tight so it does constrict, careful not to wear it too long to hinder circulation.

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

The seal is quite tight; in fact, it is so tight that it requires a bit of effort to remove the cap.
