Put your Freez Pak in the coldest part of your freezer for 6 to 10 hours. Remove and place in your ice chest on top of your food. Cool air travels downward. Use approximately half as many Freez Pak bags by weight as you would ice. For first aid use be sure to wrap in a towel.
Just freeze and use over and over! Colder than ice. Long lasting. Safe, non-toxic. Leak proof bag. Helpful Hints: Pre-cooled food will stay cooler longer with Freez Pak. Stacked Freez Paks keep food cold the longest. A small chest, fully packed, will stay cooler longer than a larger, partially loaded chest. Freez Paks can be frozen thousands of times without losing cooling power.
