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.
Today there are over 30 types of Folding Military Tool Bags. But the insulated lunch cooler, is in our opinion, the best choice for most people. It allows you to pack as little or as much food as you want, depending on its size. They come in different sizes so you can easily pack a lunch for 2 or 3 people. They are usually made of durable fabrics on the outside such as poly nylon. The inside will be a combination of plastic and insulating foil materials. Some insulated lunch coolers come with special pockets for ice packs, so be sure to keep that in mind when shopping for one.
