Cuando envía bienes sensibles a la temperatura, El hielo seco es a menudo la solución de enfriamiento. Pero how long do dry ice packs last? Es 24, 48, o 72 horas? La respuesta depende de varias variables como la cantidad de hielo seco utilizado., la calidad del aislamiento, y las condiciones ambientales durante el tránsito. En esta guía, we’ll break down the factors that influence dry ice lifespan, brindarle las mejores prácticas para optimizar su duración, y ayudarle a decidir cuándo el hielo seco es la opción correcta para su envío.

Why Does Dry Ice Duration Vary So Much?
El hielo seco sublimate (se transforma de sólido a gas) a -78.5 ° C. Several factors control the sublimation rate:
-
Cantidad de hielo seco: More dry ice equals longer cooling durations. Generalmente, 5–10 pounds of dry ice sublimate every 24 hours under standard conditions.
-
Embalaje y aislamiento: Well-insulated containers slow down the heat transfer into the box, evitando la sublimación rápida.
-
Temperatura ambiente: Los climas más calientes hacen que el hielo seco sublimate más rápido. If the shipping route passes through warm areas, more dry ice and better insulation are required.
Estimated Durations Based on Conditions:
| Cantidad de hielo seco | Estimated Duration |
|---|---|
| 5–10 libras | Arriba a 24 horas |
| 8–10 libras | Arriba a 48 horas |
| 10–15 libras | Arriba a 72 horas |
Para la punta: Always plan for a buffer—add 10-25% more dry ice to cover unexpected delays or temperature fluctuations.
How Much Dry Ice Is Required?
How Do You Calculate Dry Ice Needs?
To determine how much dry ice you’ll need, consider the following guidelines:
-
Para envíos en 24 horas: 5-10 libras de hielo seco deberían ser suficientes.
-
Para envíos de 48 horas: Double the amount of dry ice (10-20 libras).
-
Para envíos de 72 horas: Planificar 20-30 libras de hielo seco, especially if shipping in warmer climates.
The Role of Packaging and Insulation
Packaging Types for Dry Ice:
-
Bolsas de hielo seco estándar: Good for short shipments (24-48 horas) but may not provide long-lasting cooling.
-
Foil-Lined Bags: Provide better insulation for longer trips (48-72 horas).
-
Cajas aisladas: Ideal for shipments requiring temperature control over extended periods, such as pharmaceutical products.
Consejo: Always choose the right packaging for your shipment’s duration and temperature requirements.
Should You Switch to Gel Packs or PCMs?
While dry ice is ideal for freezing temperatures, alternative solutions like gel packs and phase change materials (PCM) son cada vez más populares.
When to Use Alternatives:
-
Paquetes de gel: Best for products that need to remain cool (2-8°C) Pero no congelado.
-
PCM: Suitable for shipments requiring consistent cooling but not extreme low temperatures. These materials are non-hazardous and reusable, offering a more sustainable solution.
Hielo seco vs. Alternativas:
| Característica | Hielo seco | Paquetes de gel | PCM |
|---|---|---|---|
| Temperatura | ≤ -78.5°C | 2°C a 8°C | Varía (typically 2–8°C) |
| Duración | 24–72 horas | 12–48 horas | Arriba a 72 horas |
| Costo | Moderado | Bajo | Moderado a alto |
| Mejor para | Bienes congelados | Artículos refrigerados | Productos sensibles a la temperatura |
Para la punta: When shipping ultra-sensitive items like vaccines, consider using PCMs for better stability and regulatory compliance.
2025 Tendencias en el envío de hielo seco
The dry ice shipping industry is evolving in response to new regulations, preocupaciones de sostenibilidad, and technological advances.
Llave 2025 Tendencias:
-
Embalaje inteligente: Temperature sensors and IoT devices are becoming standard in shipments, providing real-time monitoring of dry ice levels and temperatures.
-
Sostenibilidad: Biodegradable and recyclable materials are gaining traction, offering a greener alternative to traditional dry ice packaging.
-
Soluciones de enfriamiento híbrido: Combining dry ice with PCMs to maintain temperature stability for extended periods.
Preguntas más frecuentes
¿Cuánto hielo seco necesito para un envío de 24 horas??
Para un envío de 24 horas, típicamente 6-7 pounds of dry ice is required in an EPS liner or 4-5 pounds in a VIP system.
Can dry ice keep products frozen for 72 horas?
Sí, but you’ll need 15-30 libras de hielo seco, depending on insulation and ambient temperatures.
When should I use PCM or gel packs instead of dry ice?
Para envíos bajo 72 hours that require temperatures between 2-8°C, PCM or gel packs are ideal. Dry ice is necessary for deep freeze conditions.
Conclusión y recomendaciones
Understanding how long dry ice lasts is crucial for ensuring the safe transport of perishable goods. The longevity of dry ice packs depends on factors like the amount of dry ice used, calidad del embalaje, y condiciones ambientales.
Pasos de acción:
-
Assess your shipment’s needs based on travel duration and product sensitivity.
-
Choose the appropriate packaging to match your shipment’s duration.
-
Plan for sufficient dry ice and consider alternatives like PCMs or gel packs if freezing temperatures aren’t necessary.
Siguiendo estos pasos, you can ensure your products stay at the right temperature during transit, optimize shipping costs, and maintain compliance with industry regulations.
