Factors Affecting Sublimation

Many factors can affect the rate at which dry ice sublimates from a solid state to a gaseous carbon dioxide:

• the ambient temperature and humidity.
• the insulation quality of the storage container
• how often the container is opened and closed.
• the amount of dry ice in the container.
• the amount of air space in the container.

Warmer temperatures increase the rate of sublimation. Colder temperatures decrease the rate of sublimation.

Larger volumes of dry ice in a container decrease the rate of sublimation.

Storing Dry Ice

Storing dry ice in the correct polar cartons is essential to maintain product integrity and ensure safe handling.

Our cartons are designed to provide controlled insulation and ventilation, reducing sublimation while preventing dangerous pressure build-up. When opening and closing cartons, always do so slowly in a well-ventilated area, keeping hands and face clear of the opening.

Dry ice should be removed using appropriate protective gloves and tools, and cartons should be promptly and securely closed again to preserve performance and safety.

When you remove product from the container fill the empty space with wadded newspaper or styrofoam sheets. Any “dead-air-space” will cause the Dry Ice to sublimate faster.
