6 Tips for Using Dry Ice in a Cooler

Use dry ice for longer cooling Dry ice stays cold much longer than regular ice and won’t make food soggy. It sublimates into gas instead of melting.

Never seal the cooler airtight Gas buildup can pop the lid off or cause damage. Leave the drain plug open or crack the lid slightly, and tape the latch to prevent accidental sealing.

Pack dry ice at the bottom Place dry ice at the bottom of the cooler, then add a layer of cardboard or newspaper. This prevents food from freezing solid on contact.

Keep drinks above the cardboard Put drinks above the cardboard layer, not directly on dry ice. Direct contact can freeze cans solid and cause them to burst.

Handle dry ice with insulated gloves Dry ice can burn your skin on contact. Always wear insulated gloves when handling it.

Plan for evaporation Dry ice evaporates at about 5 to 10 pounds per 24 hours in a decent cooler. Buy enough for your trip and avoid storing it in a sealed car trunk.
