If I wanted to use these at a picnic, frozen, under trays of food like cheese plates, would these work to keep the tray/food cold and safe?

I use them all the time like that, except I put produce on them in AZ heat. They really help keep things fresh. However, I think Flexi Freeze works a little better. I sometimes can feel the sticky gel stuff on my hands.

They are not a thermos. Food will stay warm as long as it would in any storage container.

I don't know why not. When the ice melts it will stay inside the icepack and not get the food wet.

I would think so, yes. They are made of silicone which is heat resistant to 500 degrees F. Also, they don't absorb flavors in the same way that your silicone rubber spatula/scraper doesn't. That leaves me to wonder why you might be freezing tomato sauce in them but thats another question for another day ;)

I think they would be OK if they are airtight. Mine have been fine on the shelf as long as they are unopened, so I haven't frozen them. They get sticky if left exposed to the air.

I'm unsure of exactly what your question is...it's a little confusing. If i had to guess, you want to know if it's either good for an ice pack for a bad back...or in a backpack cooler. I think they would be great as an injury ice pack, but for backpacking...only if you aren't going too far. I don't like them for that use. I don't think they stay cold long enough to keep food or beverages at a good temperature.. If I did not answer your question, please let me know.

No, these containers are not for freezing. You would use the foodsaver bags for that.

We have only used these for cold items. Though I have not tried hot items, I can say they keep the cold food cold for at least four hours in my children's school lunch bags. We do not use ice packs.

No, I wouldn't. You would get freezer burn. They are not thick enough. You should use freezer paper. It is thicker and has a coating on the one side so food wouldn't stick.

I'm sure you could, but the stuff they are made of wouldn't hold the cold for very long. These are really fun, not sure what the freezer could add to the experience.

We use ours in the kitchen cabinets for plates, bowls, etc. I suppose they could be used in the freezer compartrment of a fridge, depending on the size of the freezer compartment. They would easily fit in a chest freezer.

No! They are not insulated, but I put a cold pack next to them in the lunch box, if I want them to stay cold. If, I don't then I don't add the cold pack!

I am not an expert but these are a special plastic blend similar to the frozen dinners containers at your local supermarket. I don't think it would be a good idea. They work in the microwave but I would never place in a regular oven at any temperature. FYI We like them except the lids are difficult to remove.

Hi 'Mom' ... These are good quality bags I don't see why they would not work for food. The only problem is when they are re-closed they are Very difficult to re-open. I would not recomend for young childern, or for things like Trail mix, that means having to re-open often.

These are pretty heavy duty glass dishes. In a lunch box, I think they'd be safe without breaking. Also, unless the glasses are held upright at all times, I would not reccommend putting anything too liquidy such as dressing or sauces. It might seep through.

I probably would not freeze them. They are pretty thin and don't appear to be designed for the freezer. They have a similar thickness to a wine glass at the top.

Food would just dry out and get hard. They are made to keep water from freezing
