Non-toxic, non-hazardous and reusable, these chemical freezer paks are capable of maintaining a sub-zero temperature "charge" in a freezer or other insulated environment for an extended period of time. This is accomplished by charging the pack (freezing at -18C) to initiate the simple chemical reaction within the pack. The pack immediately begins to absorb energy (heat) and emit sub-zero temperatures once environment temperatures begin to rise.
The Nu-Ice Ultimate Cooler Pak makes for a great cooler companion to keep contents cold and dry. Works great in lunch boxes, beach coolers, soft sided coolers and cold shipping. It also works well to extend the life of traditional bagged ice. Enjoy your recreational sports without the mess of melted ice.
