Are these containers ok to freeze or will they crack?

We have used 100's of these and they hold up well in the deep freeze. They stayed sealed and do not crack.

I had one in the freezer for months no cracks stayed sealed i love these for the value...

I would say not: I have never frozen in these particular jars, but I tried to freeze broth in the quart ones and they broke.

work fine in the freezer. they would get ice crystals if left frozen long enough. But any container that contains air will form ice crystals. To avoid (delay) ice formation, you need to vacuum seal the container.

Accidentally answered yes to this. I have never tried freezing with these. Not why I bought them. Sounds a little scary. Would think the glass would easily break.

Yes, you can put them in the freezer, however...wait until the contents thaws, if you try to force it, they may crack, break off a corner. They also do not survive being dropped on the floor very well.Hope that helps, other than that I love using them. I like squares rather that round containers for stacking.

I don't think they will break if frozen because they seem to be substantial and pliable enough to withstand freeze, but I have not tested them. I have been very pleased with how well they are holding up after several dishwasher cycles. Still look and feel brand new.

I'm not sure about freezing. I'd think you could but they have a 6 month shelf life :)

Have not tried it.Do not know if it would become brittle in the freezer, but they are cheap enough that you could give them a try. If it does not work out you can still use them for many other things.If it does work in the freezer let us know. An interesting use.

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.

While the lids themselves should be freezer safe, I would not recommend putting glass (the bowls) in the freezer because they likely would crack during the "freeze-thaw" cycle. Tupperware makes these nifty clear plastic containers with dark red top which hold about 4 ounces. These are freezer safe -- for instance, one could freeze small portions of homemade pesto in these little guys and pull one out at time as needed. Hope you find my input helpful.

According to the manufacture, they are freezer safe. My wife and I use freezer bags or plastic storage containers to store items in the freezer.

i have used them in the freezer and also sent them to school with my 4yr old, and they have not leaked or cracked. I make sure they are not filled to the brim and the food is moveable so that they don't explode and keeps the seals in place

Yes, with cautions. Leave plenty of headroom for freezing items to expand and don't overfill. Don't change temperatures suddenly. I only put the food in the freezer from room temperature, and I don't heat suddenly. I feel a little more secure with these in the freezer than thinner jars, but a broken glass would not surprise me at all.

I have not done that yet. You may want to try it first. I do use these a lot, I just never froze them. Sorry I could not be more helpful.

Yes! I have placed them in the freezer many times, no cracks or wear signs!

The containers are designed for use in the refrigerator. We do not recommend using in the freezer.

They have been in my freezer several months. Well made, and I do not think breaking is an issue.
