Can you put more than 6 ounces in them and freeze them without them bursting, leaking?

I have consistently frozen between 8 and 10 oz. in the bags and haven't had a problem with them leaking.

I've done as much as 8 oz and had no issues. I've used atleast 300 bags and only ever had 1 leak

We have not knowing we did and it froze just fine. 5 days later I used it and there was no leaking. They were perfect!!

I've tried freezing 7 ounces. Not a problem freezing without bursting. You can try freezing them upright though it will take more space than laying them flat.

I have not personally tried to freeze anything yet, but they are glass so I don't see why you could not use like a regular mason jar (leave enough space for expansion). Even if you do not use as intended, you won't be disappointed with these little jars. My friend uses the set I gave her for salad dressings because they do not spill the liquid.

I have never done this myself. The only problem I can see would be getting them through the opening once they are frozen. If the opening is big then no problem.

Yes. Soak them in the sink for about 20 minutes, then freeze them. I keep mine in ziplock bags because they do leak a little as they thaw. They stay pretty cold though.

I would think they would freeze well. I used them fairly quickly, so I didn't have to freeze them. I will tell you they were not all intact when they arrived. It didn't matter for my purposes, but just saying.

I have 2 in the freezer now! We use them usually within two weeks so I can't speak for them after that. You could easily put inside a ziplock or other freezer item for additional protection. Please note only 4oz so fills up quickly.

I do not have a direct answer but if I froze them I would open them and dump them out in a ice cube tray and freeze them that way. Reason being I am not sure that the plastic container is designed to be frozen? or rated to be frozen. Just my 2 cents maybe some one will chime in their thoughts to help answer your question.

You can wrap them in cling film tightly, and the place them in a ziplock bag and remove as much air as possible. Store in the pantry. I'm not sure if they can be frozen though.

Yes but they don't seal very well so if you are going to freeze for more than a couple of days, freezer burn will most likely occur.

my containers hold the liquid with no problem. I freeze liquid in it but if they fall they will break and crack.

I think they can. I haven't tried it myself but the standard plastic bottles can be frozen. Not sure?

You could if you use the metal end on a hard surface . Make sure to place the ice in a waterproof nylon bag 3-5 min after taking them out of the freezer. Cheers!

I never had an issue with them leaking and I used them everyday for six months. The only problem would be if they are overly full then frozen, the top won't stay on then. Just don't fill to the very top.

Yes, but don't pour hot water directly into them. Fill them with cool tap water, then heat in a microwave oven to minimize the risk of cracking due to sudden thermal expansion. The same goes for cooling... Wash them only after they have cooled, and don't wash in hot water when they are cold. (I learned all this the hard way.)

the packaging says 5 ounces. I am sure that you can get a little bit more in there, but if you over stuff them, they do tend to leak out a bit when you are trying to shut them.

I have not tried to put them in the freezer. I am writing this to you as I sit next to the pile of used ones that need to be heated again to make them liquid, they become solid after use. That pile has been there for several weeks. Really not worth the money. I would not buy these again, they are a total pain. If after you heat them if there is even one crystal left, this can be very hard to see, they will just reheat when you take them out of the hot water and you are stuck heating them again to reset. They do not stay warm for nearly long enough to make them worth it. I would strongly urge you to skip these and go with an old fashioned water bottle. Sometimes an oldie is a goodie.

Yes, they can. If you intent to keep them permanently in your freezer, make sure that automatic defrosting system is working well.
