I have used cambro carriers for years while working for a catering company. They hold temperature for a long time and are well built. I have kept soups/chowders in a cambro for hours and have pulled them out piping hot. Many times I have seen cambros dropped off trucks and survived, the food wasn't so lucky:p
When you put food in them, wrap the container in plastic wrap and then in foil. This keeps the food in the pan(plastic wrap) and helps keep the temp (foil). If you are using them to keep food cold, fill up any empty space with ice packs or bags of ice.
I have not worked with carlisle but I'm sure they are similar.

Have anyone used the insulated Cambro carriers to transport food? I would like to know if they really keep the contents hot/cold as they say here:

There is also another brand called Carlise, any input on the comparison or how good the insulated carrirers work would be great, thank you.
