THE BASICS OF PACKING DRY ICE.

The article presents tips on how to pack dry ice. Two 10 inch square blocks of 2 inch thick dry ice that is a standard 10 pound block will keep 20 pounds of frozen foods frozen for approximately three days. To make dry ice last longer, fill dead air space with wadded newspaper or regular ice frozen in milk cartons. Be careful to wrap the specimen in a towel to prevent the dry ice from creating freezer burn spots or mix dry ice and regular ice to save on shipping weight. Dry ice is available in grocery stores in many southwestern states.
