5 Things to Know About Using Dry Ice in a Rotomolded Cooler

Dry ice works well in rotomolded coolers The thick insulation slows sublimation, giving you days of freezing temperatures—better than cheap coolers.

Never seal the cooler airtight CO₂ gas builds pressure as dry ice sublimates. Leave the drain plug open or crack the lid to prevent bulging, cracking, or the lid blowing off.

Wear gloves when handling dry ice Direct contact causes frostbite. Always use insulated gloves.

Wrap dry ice before placing it inside Direct contact with the plastic at -109°F can crack even rotomolded coolers over time. Use newspaper or a towel as a buffer.

Keep the cooler in a well-ventilated area CO₂ is odorless and heavier than air—it displaces oxygen. Never use dry ice inside a car or tent.
