how long does dry ice last in freezer
Dry Ice Expiration Date. Of course, dry ice lasts for a shorter period of time if it is not stored properly. It subliminates (turns from solid form to gas form) at a rate of about 5-10 pounds every 24 hours. So, if you need about 15 pounds of dry ice for the next day you need to buy 20-25 pounds the day before.
