- Line the bottom of a cooler with newspaper or paper shopping bags and place heat packs across the bottom. Place the food on top and another heat pack on top of the food. Throw things like your picnic rug, table cloth or towels on top to fill empty space and keep the heat in. Continue to fill your cooler box with your other picnic essentials.
