How to Build a Food Cooler

Making your own cooler doesn't have to be a huge undertaking. In fact, you don't even have to spend much, if any money. At the store, coolers can cost over $25. Larger coolers average around $50 or $60. Did you know you can make your own cooler at home for a fraction of the price. It may not look at nice, but it will get the job done. If your only goal is to keep your food cold, a homemade cooler is all you need.

Instructions

    1

    Surround every inch of the box with packaging tape. You don't need to cover the top flaps, but the rest of the box should have at least 1 layer of packaging tape covering it. This will hold the box together once the insulation is in place. Spray insulation can put a lot of pressure on the box.

    2

    Place your food into plastic, seal-able containers and put them inside the box. Make sure the containers are a 1/2 inch away from each other and the box walls. This leaves enough room for the insulation to surround each food container.

    3

    Fill the gaps between the containers and the walls with spray insulation foam. Keep filling until right before the foam reaches the food lids. You don't want to risk foam getting into your food, so stop short of the lid seal.

    4

    Place a plastic garbage bag over the top of the foam insulation and the food lids. Then, spray more foam insulation over the bag up to the top of the box. Once you are finished, close the box flaps.

    5

    Tape a long piece of packaging tape all the way across the top flaps, but perpendicular to them. One side of the tape should stick to one of the box walls. Fold the other side of the tape over itself so that it doesn't stick to the other wall. This will keep the box closed, but easy to open.

    6

    Once the foam has dried and hardened, open the box and remove the top of the foam section. It should easily come off the top since the plastic bag acts as a barrier. You can then easily pull out the desired food container and return the foam cover to cover the rest of the cooler.
