Ice starts out at freezer temperature and will warm fairly quickly to its melting point (32 degrees F). Once at melting point, the ice will stay at the same temperature during the whole process of melting. After fully melting, the liquid starts to warm normally again. Cooler Shock ice packs also start out at freezer temperature, and will warm pretty quickly, but it's melting point is at a much lower temperature — 18 degrees F. During the whole process of melting, Cooler Shock stays at this lower temperature. This lower melting point means that when ice begins melting and warming in your cooler, Cooler Shock packs still stay cold, even as they begin to thaw.
