How long do these keep food hot? I was thinking of getting them to pack my kids lunches in an insulated lunchbox.

When I have used my hot packs, they have kept the food hot to warm for several hours say maybe 5 hours or so. Depends a lot on if the package is opened a lot. The more it is opened the less time it will stay hot. The person who said the hot pack is HOT when taken from the microwave it correct. But if left in the container, it should be okay for a child to touch by lunchtime.

It would keep the luch warm for them if it was packed in the morning. The only problem is the unit is very hot when it comes out of the micro wave so I would not wanting a 5 or 6 year old touching them at that time Older kids OK or it would be OK at lunch time or even at morning break

I have kept food warm for 2 hours...and I use the insulated pyrex portable containers.

I don't have a definate answer. It would depend on how hot the food was that to begin and how well it was insulated. We use ours in the insulated Pyrex containers immediately out of the oven. We usually serve the food within 3 to 4 hrs and it has been just about the correct temperature. I would think if the insulation was good it could at least be very warm. Very few other alternatives out there. This about as good as it gets besides bringing your own stove.

This was bought as a replacement for unit in Pyrex container hot-cold container. For foods right out of the oven, it usually keeps food warm for about 4 hours. The hot pack is an odd size, 9x12, for kids lunchbox, though.

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!

well insulated compared to other lunch bags. Cool things will say somewhat cool by lunch time. Freeze a yogurt and pack with lunch and all will stay cool and yogurt will be great to eat by lunch.

They are not insulated. I only use them for cold beverages. I don't think I would put anything hot in them.

I suppose they sweat after a certain period of time. I put them in a small cooler of mine that I use like a lunchbox. But I use it as more than a lunchbox, really, because I like to have at least two meals with me at all times -- and they last all day -- i.e., at least 8 hours. But I suppose there are days when I don't get home for maybe 12 hours, and the stuff in my cooler is still cool. By then, the fit and fresh coolers are melted inside, but still cold. And obviously, sweating a bit. I just checked the stuff that I put in there at about 8:30 this morning -- almost 9 hours ago -- still cold. Hope this helps.

The cooler bag is insulated but is not designed to maintain heat for several hours. A thermos is recommended for keeping hot food hot. Additionally, I do not recommend putting an extremely hot container inside the cooler bag as the inside could be damaged by excessive heat. If a cold lunch is packed, an ice block should be included to maintain a cold temp for several hours. Food should already be chilled when packed. Do not store in the sun or a hot car. - Kelly Lester, ceo, EasyLunchboxes

I've never had them sweat. I pack my daughters lunch at 6:30am, she comes home at 12:30 and I unpack her still cold lunch box at 1:30

The top two containers are made of plastic. I don't think that they would keep food warm. They seem to be made for cold foods. The largest container is made of plastic and fits inside a steel jacket that keeps warm food warm and cold food cold.

No they work perfectly well and has the same application as the more expensive thermos containers. They are well insulated and keep hot or cold for about 2-3 hours.

You need to put boiling water in the container and close it for about 5 minutes, that will warm it up. After that you put the hot food in. I pack it for my kids in the morning and they eat food for lunch, they say it's warm and they like it, but I never tested it. However, few times that I put the boiling water in the morning and then changed my mind and gave them someting else and not emptied out a thermos, the water was still really warm at night when I came home.

I'm not sure if it keeps food hot. I bought this for my wife and she uses it only for keeping her food cold. I have my doubts on if it could keep food warm. Maybe for a short time.

They do get hot. I would suggest a kitchen towel or a pot holder when first getting them out. Also, the big plates are too big for your average microwave. So that might factor into your purchase as well. They are nice though. I have used them for over a year and I don't even have a chipped one yet. (With 2 kids that also use them regularly, that is an amazing feat.)

I find with cold food it needs an ice pack so I imagine you would need to use an insulated thermos to keep foods really warm/hot.

They are pretty much ceramic. I love them because they hold more tea for me and sometimes I put soup in them. I have not had any trouble keeping things hot. But, honestly, depending on the air temperature, they might not keep it really hot for 20 minutes.

About 2-3 hours hot, but for up to 6 hours it keeps the food warm. I can't complaint. I am just glad that the food is still warm for their lunch. Hope this helps. ^^

Hi - i've only used the thermos for hot foods. I've heated food at about 7 in the morning and it's been hot until I eat the food at about 1:00. - never tried it for cold foods - sorry

No, these do not get hot. We are able to remove plates/bowls/cups without the whole container taking on heat from the microwave. Areas not in direct contact with food/liquid being heated are not hot. HTH
