Don’t let the “cooler” in Styrofoam cooler box fool you. It is also used to get the heat from leaving the box. Basically foam coolers keep things hot or cold because they prevent the interior fluctuation of temperature. Cold products will stay cold and hot products will stay heated. Hard cased coolers also have an additional component to help in the transfer of temperature. A traditional cooler with a hard exterior also has vacuum layer in between the compartment that holds the foam and the shell. This layer is also keeps the foam protected and reduces the risk of damage. These factors make this product extremely popular and easy to use every day.
