You may bring lunch to work or school every day, so it’s important to keep all the food in your lunch bag cool. After all, who wants to eat rotten ham sandwiches?

Why do people who like to pack their own lunch during the trip or go to work and school prefer to carry an insulated lunch bag or lunch backpack? Because it is heat-reflective, the foil-like inner layer of the bag reflects the radiant heat energy of the food back instead of absorbing the food and allowing it to escape from the bag.

As a result, compared with ordinary bags, the food inside can maintain its original temperature, and the flavor and moisture can last longer. This means that the insulated lunch bag can also prevent food from spoiling like tin foil, but it can prevent spoilage to a greater extent.
