Plan on using 5 to 10 pounds of dry ice for every 24-hour period depending upon the thickness of the insulated shipping container.This will keep everything frozen in a container up to 15 quarts. For larger containers and greater shipping times multiply dry ice quantities by this rate.lan on using 5 to 10 pounds of dry ice for every 24-hour period depending upon the thickness of the insulated shipping container.
