En la industria logística de la cadena de frío, maintaining the required temperature for sensitive goods like pharmaceuticals, mariscos, and meats is essential for ensuring product safety. Dry ice bricks and pack sheets are two effective cooling solutions widely used to achieve this. Understanding the differences between these options can help businesses select the right solution for their needs.

What Are Dry Ice Bricks and Pack Sheets?
Dry Ice Bricks
Dry ice bricks are solid blocks of carbon dioxide that sublimate at -78.5°C, providing a concentrated and long-lasting cooling source. These bricks are ideal for long-duration shipments, such as frozen foods or biological samples that require sustained, temperaturas ultra bajas.
Hojas de paquete de hielo seco
Dry ice pack sheets are flexible panels filled with small pellets of dry ice. These are often used for shorter shipments or for packaging products that require chilled, rather than frozen, temperaturas. Their flexibility allows them to conform to various package shapes, offering efficient cooling for goods such as cosmetics or pharmaceuticals.
How Do Dry Ice Bricks and Pack Sheets Perform in the Cold Chain?
Both dry ice bricks and pack sheets work by sublimating, a process where solid CO2 transitions directly to gas, absorbing heat and cooling the surrounding environment. The key differences between these forms lie in their cooling duration and flexibility.
| Característica | Dry Ice Bricks | Hojas de paquete de hielo seco |
|---|---|---|
| Duración del enfriamiento | 72–120 hours | 24–48 horas |
| Flexibilidad | Rigid, less adaptable | Flexible, conforms to shapes |
| Tipo de enfriamiento | Ultra-frozen | Enfriado (2°C–8°C) |
| Ideal Applications | Long-duration shipments | Short to medium-duration shipments |
Aplicación en el mundo real:
Por ejemplo, vaccines requiring transport at ultra-low temperatures for up to 96 hours benefit from dry ice bricks, whereas fresh pharmaceuticals needing a controlled temperature range for up to 48 hours can be efficiently transported with dry ice pack sheets.
Las mejores prácticas para usar hielo seco en el envío
Embalaje adecuado & Aislamiento
To optimize the performance of dry ice, use high-quality insulated packaging like Styrofoam or vacuum-insulated panels. Ensure containers are vented to allow CO2 gas to escape and prevent pressure buildup, which could damage the shipment.
How Much Dry Ice to Use?
Para un envío de 24 horas, usar aproximadamente 0.5 kg of dry ice per kg of product weight. Para envíos que duren más de 48 horas, increase the quantity of dry ice to account for the sublimation rate. Para viajes más largos, dry ice bricks are recommended due to their extended sublimation time.
Ladrillos de hielo seco vs.. Hojas de paquete: ¿Cuál es mejor para sus necesidades??
Dry Ice Bricks
Ideal for long shipments where products need to remain frozen for several days. They have higher upfront costs but offer longer-lasting cooling and higher capacity, making them essential for high-value, temperature-sensitive goods such as biologics or frozen food.
Hojas de paquete de hielo seco
Best for short-haul deliveries or when products require a chilled environment. They are cost-effective and flexible, fitting well around smaller packages. Sin embargo, they do not last as long as dry ice bricks, making them less suitable for long shipments.
Impacto ambiental y sostenibilidad
As the cold chain logistics industry moves toward more sustainable practices, the production of dry ice from CO2 captured during industrial processes has gained traction. This practice reduces reliance on fossil fuels and lowers carbon footprints. Además, innovations in packaging and monitoring technology are helping reduce waste and enhance the efficiency of dry ice use.
Sustainability Trends for 2025:
-
Eco-friendly packaging using recyclable and biodegradable materials
-
Smart temperature sensors for real-time monitoring to reduce waste
-
Closed-loop dry ice recycling sistemas, allowing dry ice to be reused
Preguntas frecuentes (Preguntas frecuentes)
Q1: ¿Cuánto dura el hielo seco durante el envío??
El hielo seco generalmente dura entre 24 a 72 horas, depending on the form (bricks or sheets), aislamiento, and shipping conditions.
Q2: ¿Es seguro el hielo seco para el envío??
Sí, dry ice is safe for shipping when handled properly. Always use vented containers and follow safety guidelines to prevent CO2 buildup.
Q3: How do I calculate the amount of dry ice I need?
Usar 0.5 kg of dry ice per kg of product for a 24-hour shipment. Para duraciones más largas, aumentar la cantidad en consecuencia.
Conclusión y recomendaciones
Dry ice bricks and pack sheets are both essential tools in cold chain logistics, each suited for different types of shipments. By understanding their differences and adhering to best practices, you can ensure the safe and efficient transport of temperature-sensitive goods.
