====== Cold Pack ======

Another name for an ice pack. An ice pack or gel pack is a portable plastic sac filled with water, or refrigerant gel or liquid. For use the contents are frozen in a freezer. Both ice and other non-toxic refrigerants (mostly water) can absorb a considerable amount of heat before they warm above 0 °C, due to the high latent heat of fusion of water. These packs are commonly used to keep food cool in portable coolers, or as a cold compress to alleviate the pain of minor injuries; or in insulated shipping containers to keep products cool during transport.
