Dry ice has a relatively short shelf-life and proper insulated storage is key. Once the CO2 has been compressed into a solid form, it slowly begins to revert to it’s original gas form. The better insulated your storage container is, the longer the dry ice will last. Larger quantities of dry ice hold better than smaller quantities. 10kg of dry ice in our standard polar cartons will lose about 25-30% per day. Larger quantities of dry ice (100kg+) can be stored in highly insulated rotomolded containers which can hold dry ice for approximately two weeks.

Dry ice should never be stored in an airtight container – as the dry ice sublimates it can cause a potentially dangerous build-up of pressure.

To dispose of any leftover dry ice, leave the dry ice at room temperature in a well-ventilated area and open the storage box to help the dry ice sublimate faster. Ensure that neither children nor animals can gain access to the dry ice.
