A cooler box is a compact non-mechanical wrapped box used to store food and drinks. Ice packs or ice bags are commonly placed in the box to keep the contents cool. Ice packs are usually preferred over ice bags as they tend to stay cool longer and no leakage.
Portable coolers stay cold with the magic of insulation and ice packs. The insulation, which is usually made from foam or plastic, lines the inside of your cooler, slowing down the circulation of warm air. The ice packs, meanwhile, keeps the inside of your cooler nice and chilly.
