how do you know it's safe to freeze in these containers

Yes, you can, BUT it defeats the essential benefit of keeping food fresh longer. they might also crack if over filled as liquids expand when they are frozen. The DEBBIE MEYER UltraLite GreenBoxes are Independent Laboratory tested and proven to keep fresh produce, baked goods and snacks fresh longer, without freezing. If you freeze in them you will experience freezer burn and the freshness properties will not work. In the freezer you need to create a vacuum to prevent freezer burn. You can use DEBBIE MEYER GeniusVac and DEBBIE MEYER GeniusVac Bags for the freezer. The beauty of these boxes is that you do NOT have to freeze most times because the food stays fresh for longer. Hope this helps.

Yes, they are air tight. Definitely fridge. I guess you could put them in the freezer.

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.

I've never tried to freeze them, but they are dishwasher safe so I would assume that means they are able to be frozen. They don't expand like a throw away bottle would so you would just have to be careful to leave room for the liquid to expand.

Angela - We have used these in the freezer without issue. They've been a good product for our family.

Hi Laura, I have discovered I have to be sure not to fill to top and make sure the tops snap on/ and the trick is that nothing else in freezer knocks them over be fore they freeze, I had not yet frozen orange juice all over one time/ so understand your question / they stand up fantastic in the holder, after frozen I place in plastic bag and add more as I have 3 sets of these love them,

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.

Thank you for your inquiry. These bottles along with the filter cannot be frozen. Hope this helps!!!

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 g ave her for salad dressings because they do not spill the liquid.

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.

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.

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

yes, they freeze very well. I buy them by the case and keep out a few pkgs. and freeze the rest.

When I do my meal prep I don't freeze so I wouldn't be able to answer that. However they seem very durable so I would believe so.

I haven't frozen these specific ones, but I know that freezing crispy items sometimes fails due to some moisture getting into the packaging and softening the product. I think they may freeze okay if the packaging is absolutely airtight. I do know that I've had my case of 12 for about 6 months, and they are just now starting to get less crunchy. But still tasty!

The fridge is fine. Just need to make sure not to get below the freezing point of water.

when you buy them in the store....they are not cold. Just on a shelf. I don't know why you would receive them frozen. Hmmm
