A: An inside middle layer of insulating foam is typically made from materials like durable polyurethane, polyethylene plastic or thermal batting made out of polyester fibers. While insulated, soft-sided lunch boxes or bags can often be best for keeping food cool, packing at least two cold sources, such as gel packs or ice can help.

Q: What is the Best Lunch Box?

A: Best overall lunch box: Lifewit Lifewit Large Lunch Bag As the best overall lunch box, Lifewit claims this model features an insulated lining to keep your food and beverages cold or hot for up to five hours. The exterior is made from water-resistant fabric and sports multiple pockets for additional storage.

Q: How do insulated lunch boxes work?

A: Insulated lunch boxes have two walls unlike single walled boxes. There is a vacuum between the two walls. Since, there is an absence of air between the two walls there is no medium to carry the heat absorbed by the inner wall to the outer wall. Thus, the outer wall doesn’t heat up and does not dissipate any heat in the surroundings.
