Ice pack

Common card · No. 429748

An ice pack, or cold pack (or, in specific cases, gel pack), is a portable bag filled with water or another liquid, or refrigerant gel, meant to provide cooling. They can be divided into the reusable type, which works as a thermal mass and requires freezing, or the instant type, which cools itself down using chemicals but can only be used once. The instant type is generally limited to medical use as a cold compress to alleviate the pain of minor injuries, while the reusable type is both used as a cold compress and to keep food cool in portable coolers or in insulated shipping containers to keep products cool during transport.
