How to keep food warm for hours in lunch box
If you want to send the kids to school with a hot lunch or enjoy a hot lunch at work yourself, you need a lunch box that keeps food warm.
An insulated food container or an insulated lunch box for kids will keep hot food hot for up to six hours. These are specially designed products that feature a double-walled container inside of it. The air between the two walls is removed when the product is manufactured, creating a vacuum. This prevents heat escaping, and keeps the food it contains hot.

Do insulated lunch bags keep food warm?
Insulated lunch bags keep food warm much longer than a lunch bag without that insulating layer. They are not as effective as an insulated food container at keeping food warm though.
If your goal is to keep the food hot from when it is packed in the morning till when it is eaten at lunch time, use an insulated food container. You can place that inside any type of lunch bag, insulated or not.
So, how long will food stay hot in an insulated bag, you ask. Food that is contained in a container that is not insulated (like a stainless steel lunch box or a glass lunch container) will stay hot in an insulated bag for a few hours, but will start to cool more quickly than food stored in an insulated lunch box.
If you are looking for an insulated lunch bag, SoYoung insulated lunch bags are a mindfully designed lunchbox that are made from raw, uncoated linen without PVC, BPA or phthalate. They are machine washable, come with a spill safe insert for easy cleaning and include handy carry straps and fun prints.
