Can you use these for regular food storage, like a sandwich or something, or liquids? Or does the "fresh vent" not seal these containers entirely?

I do, but they would leak liquids if tipped over. I really like mine a lot and have thought about ordering more.

Hi, I use these for anything...what I do if I'm not storing produce is merely take out the vent in the bottom, and it works great! Hope this helps!

You are correct the "fresh vent" does not seal completely. I would not recommend for liquids, sandwiches maybe. They are incredible for keeping veggies fresh!

I don't have any issues at all. I like that they seal airtight. I put the lids in the dishwasher on the top shelf. I don't know what the company says, but it's been fine for us.

i own this, with a properly placed seal it should be airtight. the seals remove for cleaning. if you do not install them correctly then it will not be air tight. they are pretty easy to install. i am happy for the price i paid. tupperware made nice canisters but they will cost you twice as much and they are not clear.

They do not leak dry goods if closed properly but in terms of being airtight no they are not.There is no seal for that.

If by generic you mean regular zip-lock or plastic bags, I have tried and found it difficult. You can put food in them and seal them in the reusable bags that come with this to save on cleaning them, but sealing regular bags is difficult. As for sealing liquid, same thing, put in zip-lock bags and then seal in the re-usable ones that come with it. The bags that come with it are extremely sturdy and very easy to seal repeatedly with the sealer.

After owning these containers for a year+ I would say no, there isn't a liquid tight seal on any of the joins between containers or lids. It's best for transporting non liquid food.

Your Foodsaver appliance removes the air and heat seals your package. There is no "zip seal" involved in preparation of your product for storage. Hope this answers your question.

Yes. I have found these containers to be leak proof. I was pleasantly surprised to see how much food they can hold. So far, they have held up nicely, and I use them frequently.

As long as you only fill them up halfway and stack them upright to store they worked fine for me. Do not microwave them to thaw or try to take the lid off while frozen unless you want a mess. They will crack if you handle them too much before thawing. For added security, I placed a rubber band around them while freezing and also in the lunch kit to ensure they didn't leak, and they never did. They worked just fine for me!

I'm not sure that sealing them would make them shelf stable anyway... Part of the reason it's good to make your own baby food is that foo has to reach high temperatures in order to be shelf stable. That takes much of the nutrients out of the fruits and veggies. Like the other posters said, I love it!

There is a rubber seal, but it is NOT leakproof. The rubber seal is ill-fitting, and mostly meant to keep moisture out for short periods, but I would never put liquid in it if there's a chance the container will be moved around and the liquid will be sloshing around. On the other hand, these containers are good for children's lunches because they are pretty easy to open and the smaller containers fit nicely in lunch boxes. The larger containers are also good for storing leftover food.

There is no seal or rubber gasket per se to create a true airtight container. However, they do appear to be relatively air tight.

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

I don't know--have never used for that purpose. I think they are only containers.

If you put them in plastic bag! In order to really seal a Mason jar, you'd have to have a specially designed top for the jar. Most things that you'd can need heat anyway, I believe you'd just be adding complexity for no benefit. The FoodSaver works great as designed....to seal food in plastic. Canning works great as designed....to seal heated/cooked food in glass/metal. The two processes are different enough that you do not want to mix them.

Yes, you can use a VACUUM-type sealer that sucks all the air out of the jar -- I do it all the time. Food Saver brand does it very well, as long as the unit is capable of sealing 'cannisters'.

I wouldn't use this for food storage at all ! it not made for that, it's not ait tight, you have no idea if the material if free of toxins or full of them. A better idea would be to but a Vittels Vault, they're great for food storage, they lock down air tight. Amazon carries them in many sizes I suggest checking them out.
