Packs de glace sec contre gel: Which Lasts Longer in Cold Chain Shipping?

En ce qui concerne l'expédition de produits sensibles à la température, understanding which refrigerant—packs de glace sèche ou de gel—lasts longer is crucial for ensuring the safe delivery of goods. Dans cet article, we will break down the key differences between these two cooling methods, their longevity, and the scenarios where each is most suitable for use in cold chain logistics. With proper knowledge, you can make informed decisions to ensure your products reach their destination at the required temperature.

• How do gel packs compare to dry ice for long-lasting cooling?

• Which cooling solution is more suitable for different shipping conditions?

• What are the latest trends in cold chain logistics for 2025?

What Is Dry Ice, and How Does It Work for Shipping?

La glace sèche est la forme solide de dioxyde de carbone (Co₂) that sublimates directly from a solid state into a gas at a temperature of -78.5°C (-109.3°F). This ultra-low temperature makes dry ice an excellent option for maintaining extremely cold temperatures during the shipment of perishable items such as pharmaceuticals, échantillons biologiques, et aliments surgelés.

Dry ice works through sublimation, which means it transforms from a solid directly into gas, absorbing significant amounts of heat. It is particularly effective when used with proper insulation, helping shipments maintain freezing conditions for long durations. Dry ice is commonly used for shipments requiring deep-freezing, comme les vaccins, glace, et la viande, due to its ability to maintain temperatures well below freezing.

Packs de glace sec contre gel: Combien de temps dure la glace sèche?

Dry ice has a longer cooling duration compared to many alternatives, including gel packs, thanks to its extremely low temperature. En moyenne, dry ice can last anywhere from 18 à 72 heures, depending on various factors like the amount of dry ice used, the packaging, and the insulation involved.

Key Insight: Dry ice lasts longer than gel packs, especially for products requiring low temperatures over extended periods.

Que sont les packs de gel, and How Do They Compare to Dry Ice?

Gel packs are flexible pouches filled with a gel solution that freezes at temperatures around 0°C. These are typically used for products that require refrigeration but not freezing, comme les produits frais, laitier, and certain medications.

Although gel packs are convenient for short-term shipping, they do not last as long as dry ice. Gel packs are better for shipments requiring a mild, controlled temperature range (usually between 1°C and 5°C). While they are reusable and cost-effective for short-term cooling, they lack the ultra-low temperature capabilities of dry ice.

How Do Gel Packs Compare to Dry Ice for Long-Lasting Cooling?

Gel packs are a more affordable option, especially for short shipments, but they are not as effective as dry ice for long-term cooling. Dry ice is ideal for shipments that require sustained low temperatures, whereas gel packs work best for products that only need to remain cool for a few hours or a day.

Key Insight: For shipments requiring prolonged refrigeration or freezing, dry ice is a superior option. Gel packs are more suitable for shorter durations and moderate cooling needs.

Which One Is More Suitable for Different Shipping Conditions?

Choosing between dry ice and gel packs depends on the specific conditions of your shipment. Dry ice is ideal for products that need to remain frozen, comme les produits pharmaceutiques, échantillons biologiques, and frozen food. For long-distance shipments that span multiple time zones, dry ice is often the best solution.

En revanche, gel packs are a better choice for items that need to remain cool but not frozen. Par exemple, chocolat, produits de beauté, and certain medications benefit from gel packs as they offer a gentle and controlled cooling effect over short distances.

Practical Tip: For long-distance shipping across several time zones, dry ice will maintain the necessary sub-zero temperatures. For products that only need to stay cool for a short time, gel packs paired with insulation may be sufficient.

2025 Latest Trends in Cold Chain Shipping

The cold chain logistics industry is continually evolving, with advancements in technology and sustainability driving changes in how products are shipped.

Emerging Technologies in Temperature Control

• Smart Temperature Sensors: These sensors can be incorporated into both dry ice and gel pack shipments to provide real-time monitoring of temperature fluctuations during transit.

• Matériaux à changement de phase (PCMS): These materials are becoming increasingly popular as they offer more controlled and stable temperature management over extended periods.

Market Insights for 2025

• Sustainability Demand: There is an increasing demand for eco-friendly cooling solutions in the logistics industry. While dry ice is effective, it has a higher environmental impact due to its energy-intensive production. Par conséquent, companies are exploring more sustainable alternatives such as biodegradable gel packs and phase change materials (PCMS).

• Increased Adoption of Gel Packs: With sustainability becoming a primary focus, packs de gel, which are reusable and environmentally friendly, are expected to see greater adoption for short-term temperature-sensitive shipments.

Questions fréquemment posées

Q1: Combien de temps dure la glace sèche pendant l'expédition?
Dry ice typically lasts anywhere from 18 à 72 heures, depending on the amount used and the quality of insulation.

Q2: Les packs de gel sont-ils réutilisables?
Oui, many gel packs are reusable. They can be refrozen after use, but their cooling efficiency may degrade over time.

Q3: Can I ship pharmaceuticals with gel packs?
Gel packs are suitable for pharmaceuticals that require refrigeration but not freezing. For medications needing sub-zero temperatures, dry ice is recommended.

Conclusion & Recommandations

En conclusion, dry ice is best for shipments that require sustained low temperatures over longer durations, comme les produits pharmaceutiques, aliments surgelés, et des échantillons biologiques. Packs de gel, while more cost-effective and environmentally friendly, are ideal for short-term shipments and items that need to remain cool but not frozen.

Recommended Actions:

• For Long-Distance Shipments: If you’re shipping items that need consistent sub-zero temperatures, use dry ice with high-quality insulation.

• For Short-Distance Shipments: For products like chocolates, produits de beauté, or certain food items, gel packs are sufficient and more sustainable.

• For Eco-Conscious Shipping: Explore sustainable alternatives like PCMs that offer improved performance and minimal environmental impact.
