are these airtight for use in the freezer?

I've never used them in the freezer for something like raw meat. I've used them for basil leaves and stuff like that. The ziplock freezer bags with the air pump are pretty great for keeping things fresh.

Sorry, I've never used it in the freezer. While I'm not sure the definition of freezer safe I will say, they are sturdy and the lid screws down tightly. I would put mine in the freezer if the need arose.

I have never tried to put them in the freezer, but as they don't tightly, I wouldn't try it.

They have been safe in a freezer as longas you leave space at top. They work okay in micro wave but I use plastic wrap instead of lid because lids warp with heat. Have never tried to use in oven

Yes the lids seem airtight to me. They have screw on grooves that secure on pretty well. Interesting idea to use them for dry snacks. Will have to try.

No, not necessarily. They can be stored in airtight container until next use. They are very dry. I've had mine for months stored this way..

I believe so, I put mine in the freezer all the time. I make a large batch, freeze and take out when I need them.

I have no problem with them in the freezer for a short period. Like any frozen glass it can burst when handled, use caution. Joe

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

Sure. They will work better than regular freezer bags if they are sealed correctly.

I have never tried them in the freezer but my guess is no. The material they are made of does not have the same look/feel of material that I know can be frozen. My guess is that these would crack.

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.

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

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!

Yes, they are ideal fir freezing. I have used them for two years nearly and I freeze most of the food I bag.

Leanne, I would say you'd have no problem with them in the refrigerator. I'm very hesitant about saying "yes" to the freezer because I don't know what you'd be putting in them or how full you fill them (liquids expand when frozen and therefore would break the glass). Regards, Al

I am using them for Bath bomb frizzes. So, they will not be in the freezer.
