The Insulated Lunch Cooler Bags are relatively new products but the idea of keeping foods cold goes back to the mid 1800s. The purpose of keeping your food cool is mainly to help prevent harmful bacteria from growing in to large populations. It started off by hauling ice to homes and stores from hundreds of miles away. In the 1950s the Coleman Company developed a plastic lined cooler which helps insulate food better, and keep things cooler longer. Around this same time the Aladdin Company developed the lunch bag. Since then there have been many twists on ideas that have led to the development of the insulated lunch cooler.
