Can Gel Packs and Dry Ice Be Used Together in Cold Chain Shipping?

Oui, combining gel packs and dry ice in cold chain logistics can be an effective solution. While each cooling method has its advantages, proper layering and packaging are essential to ensuring both work together efficiently.

Gel packs maintain cool but not freezing temperatures (2–8 ° C), while dry ice provides ultra-cold temperatures (below –20°C). By combining the two, you can manage different temperature needs in one shipment, which is especially useful for shipping products like médicaments ou aliments surgelés that require both cooling and freezing.

How Do They Work Together?

• Glace sèche offers an immediate, intense cooling effect that keeps products frozen.

• Packs de gel offer stable, long-term cooling for items that need to stay cold but not frozen.

Using both helps extend shipping times, ensuring that products remain at the correct temperature from the warehouse to their destination.

What Are the Benefits of Combining Gel Packs with Dry Ice?

Here are the main advantages of combining both cooling methods in your shipments:

1. Enhanced Temperature Control

Gel packs provide consistent, stable cooling for longer durations, while dry ice ensures frozen items stay solid. Ensemble, they create a layered temperature system, which is essential for shipments that contain a variety of products with different temperature needs.

2. Durée de refroidissement prolongée

While dry ice sublimates quickly, its cooling effect can be extended when paired with gel packs. Gel packs take over once the dry ice sublimates, helping keep the products within the required temperature range for longer durations.

3. Rentabilité

Using gel packs alongside dry ice allows you to use less dry ice, reducing shipping costs without compromising the quality of the cold chain.

How to Safely Combine Gel Packs and Dry Ice

Proper packaging is crucial when combining these cooling methods. Follow these steps for maximum safety and efficiency:

Étape 1: Choose the Right Packaging

Select insulated containers capable of withstanding the extreme temperatures of dry ice. These containers should also allow gas release to prevent pressure buildup due to dry ice sublimation.

Étape 2: Layer Gel Packs and Dry Ice

• Lieu gel packs at the bottom of the container to ensure they maintain the correct temperature for longer.

• Ajouter glace sèche sur le dessus, ensuring it does not directly touch the gel packs. This separation prevents the gel packs from freezing and ensures the proper cooling conditions.

Étape 3: Add Products and Seal the Package

Place the temperature-sensitive products between the gel packs and dry ice. Ensure the product is well-insulated and protected from any extreme cold. Seal the container tightly and label it to indicate the presence of dry ice.

Étape 4: Surveiller la température

Utiliser un temperature monitoring device to track conditions inside the container during transit. This ensures that the product remains at the optimal temperature throughout the journey.

Are There Any Safety Concerns When Using Both Together?

While combining gel packs and dry ice can be effective, there are several important safety precautions to follow:

• Ventilation appropriée: La glace sèche sublimait le dioxyde de carbone, which can displace oxygen. Ensure your packaging allows for gas release to avoid suffocation.

• Handling Dry Ice: Toujours porter gants isolés when handling dry ice to prevent frostbite. Avoid contact with bare skin.

• Packaging Integrity: Ensure the packaging can withstand the extreme cold of dry ice and prevent leaks or cracks.

2025 Tendances de la logistique de la chaîne du froid: The Future of Hybrid Cooling

Dans 2025, the cold chain logistics industry continues to innovate. Here’s what we can expect in the coming years:

1. Hybrid Cooling Solutions

Innovative hybrid refrigerants, tel que Matériaux à changement de phase (PCMS), are becoming more popular. These materials work alongside gel packs and dry ice to extend cooling duration while reducing the need for excessive dry ice.

2. Sustainable Refrigerants

Eco-friendly alternatives are gaining traction, y compris biodegradable gel packs et carbon-neutral dry ice. These innovations help reduce the environmental impact of cold chain shipping.

3. Surveillance de la température intelligente

Advancements in real-time temperature monitoring systems allow for better tracking and reporting during transit, ensuring products are kept within the required temperature range.

Questions fréquemment posées

Can I combine gel packs with dry ice for air shipping?

Oui, gel packs and dry ice can be used together for air shipping. Cependant, ensure your packaging complies with airline regulations, and that dry ice is properly vented.

How long can dry ice last with gel packs?

Dry ice lasts longer when paired with gel packs. The gel packs absorb heat and help slow the sublimation rate of dry ice, extending its cooling duration.

What types of goods should never be shipped with dry ice?

Avoid using dry ice for live animals, raw produce, ou carbonated beverages. These products can be damaged by the extreme cold or the sublimation of carbon dioxide.

Conclusion

Combining gel packs and dry ice is an excellent way to optimize cold chain shipping for temperature-sensitive products. By following proper packing procedures, ensuring safety regulations, and monitoring temperatures throughout transit, you can extend shipping durations while maintaining product quality.

Étapes suivantes:

• Review your shipment’s temperature requirements and determine whether gel packs, glace carbonique, or both are necessary.

• Consult with your logistics provider about specific regulations for shipping with dry ice and gel packs.

• Surveiller la température using real-time tracking systems to improve your future shipping strategies.
