These specially designed containers ensure the safe storage and transportation of dry ice while maintaining optimal temperatures to prevent sublimation. In this guide, we’ll explore the different types of dry ice containers available, their applications, and key features to consider when selecting the right one for your needs.
Comparison of Dry Ice Container Types and Applications
| Container Type | Insulation Material | Capacity | Sublimation Rate | Applications |
|---|---|---|---|---|
| Insulated Storage Chest | Urethane Foam | 1.6 – 5 Cu Ft | Low | Food distribution, medical transport |
| Foam Insulated Container | Molded EPS Foam | Variable | Medium | Industrial cooling, food transport |
| Heavy-Duty Dry Ice Bin | Double-Wall Polyethylene | Varies | Low | Bulk storage, pharmaceutical shipping |
| Lightweight Storage Chest | Special Formulated Insulation | 85 lbs | Very Low | Home use, small-scale transport |
| Plastic Insulated Chest | High-Density Plastic | Various | Low | General-purpose storage |
Understanding Dry Ice and Its Importance
Dry ice is the solid form of carbon dioxide (CO2) and is widely used for its cooling properties. Its surface temperature is around -109.3°F, making it effective for preserving food and pharmaceuticals. However, it sublimates directly into gas, which can pose safety hazards if not handled correctly.
Key Characteristics of Dry Ice
- Temperature Control: Essential for maintaining the quality of perishable goods.
- Sublimation Rate: The rate at which dry ice turns into gas; a crucial factor for efficient storage.
- Durability: Containers must withstand tough shipping conditions without compromising insulation.
Types of Dry Ice Containers
Insulated Storage Chests
Insulated storage chests, such as those offered by Sonoco ThermoSafe, are designed for long-term storage of dry ice. They typically feature double-wall construction filled with urethane foam insulation, minimizing sublimation rates. These chests are ideal for food distribution, ensuring that items remain frozen during transit.
Foam Insulated Containers
Foam insulated containers, like those provided by Polar Tech Industries, are lightweight and molded from EPS foam. They often come with tight-fitting lids to prevent gas escape. These containers are versatile and suitable for both food transport and industrial cooling applications.
Heavy-Duty Dry Ice Bins
Heavy-duty bins, available from suppliers like Cole-Parmer, are built to handle bulk storage and transportation of dry ice. Their robust construction and excellent insulation properties ensure that dry ice remains effective for extended periods, making them suitable for pharmaceuticals and other sensitive materials.
Lightweight Storage Chests
Lightweight storage chests, such as those from Fisher Scientific, are perfect for home use or small-scale transport. They are designed with special formulated insulation to achieve the lowest sublimation rates, making them ideal for occasional use.
Applications of Dry Ice Containers
Food Distribution
In the food industry, maintaining the cold chain is crucial. Dry ice containers are commonly used for transporting frozen foods, ice cream, and other perishables. Their ability to keep items at sub-zero temperatures ensures freshness and quality upon delivery.
Medical Transport
For the pharmaceutical industry, dry ice containers provide a reliable solution for transporting temperature-sensitive medications and biological samples. The insulation technology used in containers from Greco Gas ensures that these products remain viable during transit.
Industrial Applications
Industries that require cooling for manufacturing processes, such as in the production of chemicals or electronics, also utilize dry ice containers. These containers help in maintaining the required low temperatures, ensuring product integrity.

FAQ
What is dry ice and how is it different from regular ice?
Dry ice is solid carbon dioxide (CO2) that sublimates at -109.3°F. Unlike regular ice, which melts into water, dry ice transitions directly into gas without leaving any residue.
How long can dry ice be stored in a container?
The duration depends on the container’s insulation and the amount of dry ice. For example, some insulated chests can keep 85 pounds of dry ice for up to 6 days.
Are dry ice containers reusable?
Yes, most dry ice containers are designed to be reusable and can be used multiple times as long as they are properly maintained.
What safety precautions should be taken while handling dry ice?
Always use gloves or tongs when handling dry ice to avoid frostbite. Ensure adequate ventilation when using dry ice indoors to prevent a buildup of CO2 gas.
Can dry ice be shipped?
Yes, dry ice can be shipped, but it must comply with regulations set by the Department of Transportation (DOT) and may require specific labeling.
What types of insulation are best for dry ice containers?
Urethane foam and molded EPS foam are popular choices due to their excellent insulation properties, which minimize sublimation rates.
How do I choose the right dry ice container?
Consider your specific needs such as capacity, insulation type, and the duration of storage. Containers like those from DACO Corp offer various options to fit different requirements.
Can I use dry ice in a standard cooler?
While you can use dry ice in a standard cooler, ensure that the cooler is properly ventilated to prevent gas buildup, and take precautions to avoid direct contact.
What are the common uses for dry ice containers?
Common uses include food transportation, medical sample preservation, industrial cooling, and shipping perishable goods.
Where can I purchase dry ice containers?
Dry ice containers can be purchased from suppliers such as Walmart, Thomas Scientific, and dedicated industrial suppliers like Bonar Plastics.
