What Are the Key Differences Between Dry Ice and Ice Packs?
Dry ice et packs de glace each have unique advantages, but choosing the right one depends on your needs.
Dry Ice
Dry ice is frozen carbon dioxide that sublimates at -109°F. Unlike regular ice, dry ice doesn’t melt into liquid, which means it keeps everything dry. It is ideal for long shipments, keeping items frozen for extended periods.
Packs de glace
Packs de glace, also called packs de gel, are filled with refrigerants or water and often used for shorter shipments. They are typically kept frozen and thaw over time, which means they are best for keeping items chilled, not frozen.
Key Differences
| Fonctionnalité | Dry Ice | Packs de glace | Votre avantage |
|---|---|---|---|
| Température | -109°F | 35°F to 45°F | Dry ice keeps items frozen, ice packs maintain a chilled state |
| Longevity | Lasts 5-7 jours | Lasts up to 6 heures | Dry ice is better for long-distance shipments |
| Sécurité | Risk of burns, requires special handling | Easier to handle, safer | Ice packs are easier and safer for regular handling |
| Coût | More expensive | More affordable | Ice packs are less costly for short shipments |
Which One Should You Use for Shipping Perishable Goods?
Packs de glace: Best for Short-Term, Local Shipments
Packs de glace are the best choice for shipping chilled items that don’t need to remain frozen for long. They are ideal for local deliveries ou one-day shipments of products like dairy, légumes, and fresh meat.
Dry Ice: Best for Long-Distance, Frozen Shipments
For items that need to remain frozen over multiple days—like viandes surgelées, fruit de mer, ou glace—glace carbonique is the optimal solution. It lasts much longer than ice packs and doesn’t create liquid messes, keeping the contents dry and frozen.
How to Maximize Efficiency and Safety with Dry Ice and Ice Packs?
Pre-chill Your Items
For both glace carbonique et packs de glace, pre-chilling your products before packaging ensures maximum cold retention. Refrigerate items for at least 12 hours prior to packing.
Layer Your Pack Effectively
When using glace carbonique, ensure that 60% of your dry ice is placed at the bottom, et 40% is placed on top to ensure even cooling. For packs de glace, use a similar approach, but ensure they are packed tightly around your items to reduce air exposure and maximize cooling efficiency.
Monitor Temperature Throughout Shipping
It’s vital to include temperature monitors when shipping with either dry ice or ice packs, especially for critical shipments like pharmaceuticals or biologics. En utilisant disposable temperature loggers can ensure that items remain within the required temperature range.
