Can these be used for freezing?

Yes, they work very well and do not pick up or spread odors. Can be used multiple times if food is not liquid.

Yes. Take caution in shuffling around in the freezer as other frozen items will pop this bag. These work great but I would imagine a vacuum seal would be better for a long term freeze (more than a month).

I would say no. I use old ice cream buckets for that. I don't think they are made for the freezer.

I have not used mine in the freezer since they have a tendency to crack on the bottom. Once they crack they do not work but use E6000 glue on the crack to once more seal from air getting into them.

I haven't tried freezing mine, but as long as you leave room in the tubs to allow for expansion it should be fine. They are dishwasher and microwave safe so I can't imagine they aren't freezer safe as well.

I haven't used them for freezing (got them for my Sunday school class to grow seeds in a planting medium with the lids as sort of a "greenhouse".

Yes! I use mine for freezing all kinds of things. The only drawback is (and this happens in any condition, not just the freezer) every once in a while they "unvacuum" It usually happens quickly because of not zipping them tightly enough, but sometimes it is because of a bad bag or small hole in the bag, so I check in a day or two to avoid freezer burn, stale food, etc.

Extremely strong glass. Very thick. I would think if you left room for some expansion of frozen liquid, they should be fine. I have not tried freezing anything in them. This is only my opinion based on how sturdy they are.

If they are already frozen, I don't see why not. They would, however, be open at the bottom. Just my opinion, though.

I have used them to freeze leftovers. As long as there is enough room left for the contents to expand when frozen, it should be fine.

I have not tried to freeze them. And I don't think it would work very well. If the expanding liquid didn't break them, the extreme cold would probably make them more prone to crack

I don't know what kind of freezer you have. My guess is these are not intended for use in a freezer.

They work great for ice cream, so I don't see why not! They're not really sealed, though, so freezer burn might be a 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 have never tried to put them in the freezer, but as they don't tightly, I wouldn't try it.

I have not used for freezing food but think they would work well. They are a heavier plastic than some and quite airtight. 2oz is still quite small.

Yes, they can be used for freezer. However, they are not very thick so double bagging would be good and they are NOT "zipper" type bags. I am so glad to be able to find these because I have always had so many uses for just a plain quart size bag WITHOUT all the zipping parts. I was NOT able to buy plain baggies anywhere until I found them here-so I stocked up. Definitely would buy again and again as long as they are available!
