Why Use Dry Ice Sheets for Medicine Transport?
La ciencia detrás del hielo seco
El hielo seco es dióxido de carbono sólido que se sublima a –78,5°C (–109,3 °F). A presión atmosférica, CO₂ has no liquid phase; it moves directly from solid to gas when warmed. This process absorbs a large amount of heat, maintaining ultra low temperatures inside insulated containers and preventing moisture buildup. For medicines that must stay below –50 °C, such as certain mRNA vaccines, this level of cold is essential.
Benefits Over Gel Packs and Phase Change Materials
Colder temperatures and longer duration. Dry ice holds temperatures as low as –78 °C for several days. Gel packs freeze around 0 °C and are better for keeping items cool but not frozen. Materiales de cambio de fase (PCM) may offer reusability but they have lower thermal conductivity and cannot achieve ultra cold temperatures.
Sin residuos líquidos. Porque el hielo seco se sublima directamente en gas, it leaves no water that could damage packaging or contaminate pharmaceutical products. Ice packs can leak if punctured and create messes.
Vida útil extendida. The extreme cold slows bacterial growth and enzymatic activity, extending the shelf life of biological products.
Lightweight and space efficient. Dry ice has a lower density than water ice, reducing shipping weight and allowing more product per shipment.
Consideraciones ambientales. Dry ice is often produced from recycled CO₂ and sublimates back into gas, minimizing water waste. It’s still important to source from suppliers focused on carbon capture and eco friendly production.
Comparación de métodos de enfriamiento
| Método de enfriamiento | Rango de temperatura | Duración | Ventajas | Desventajas | Mejor para |
| Capa de hielo seco | Hasta –78°C | 2–5 days depending on insulation | ultra frio, Sin residuo, ligero | Requiere ventilación; weight limits on air transport | Vacunas congeladas, biológicos, envío de larga distancia |
| Paquete de gel | 0 °C a –10°C | 12–48h | Reutilizable, más seguro de manejar | Limited cold capacity; may leak | Chilled medicines, viajes cortos |
| Material de cambio de fase (PCM) | Ajustable (p.ej., +5 ° C, –20 ° C) | 24–72h | Reutilizable, temperatura estable | Lower thermal conductivity and slower cooling; rango de temperatura estrecho | Controlled room temp drugs, cadena de frio moderada |
| Hielo tradicional | About 0 °C | 8–24h | Ampliamente disponible, barato | Se derrite en el agua; riesgo de contaminación | Alimento, non medical uses |
Consejos y consejos prácticos
Assess the required temperature range. If your medicine must stay frozen (p.ej., –70°C), dry ice sheets are essential. For refrigerated drugs (2–8 ° C), gel or PCM packs might suffice.
Balance duration and cost. Premium dry ice sheets can maintain temperature stability for over 120 hours but may cost more upfront. Consider reuse cycles and total cost of ownership.
Combinar métodos de enfriamiento. For multi stop routes or last mile delivery, layering –20 °C packs with –78 °C dry ice can balance safety and cost.
Caso del mundo real: Durante el lanzamiento de la vacuna COVID 19, pharmaceutical companies used dry ice to maintain –70 °C for Pfizer’s mRNA vaccines, enabling safe delivery across varied climates. Sin hielo seco, these vaccines would have lost potency or required expensive ultra cold freezers.

Recomendaciones centradas en el usuario
Match the sheet size to your cooler. Large sheets provide more consistent coverage but may waste space in small containers. For insulin travel cases, several small sheets often work better.
Select reusability based on shipping frequency. If you ship weekly, durable reusable sheets save money. Occasional shipments may justify single use options.
Verify certification for medical use. Always ask suppliers for testing data and certifications; avoid uncertified products marketed as “medical grade.”
Consider the environmental footprint. Prioritize sheets made with recycled CO₂ and recyclable materials to minimize emissions.
Estudio de caso: A biopharmaceutical firm switching to reusable nano coated dry ice sheets reduced coolant costs by 187%, saving $38 000 in the first year. Their finance team initially doubted the ROI, but the extended lifespan and reduced waste justified the investment.
How to Pack Medicines with Dry Ice Sheets
Guía de embalaje paso a paso
Calcule el hielo seco requerido. Usa la fórmula (Volumen del refrigerador × diferencia de temperatura × 0.12) ÷ 150 × 1.25. Por ejemplo, a 100 L container traveling from 25 °C to –70 °C needs about 9.5 kg of dry ice.
Prepare the dry ice sheet. Hidratar (si es necesario) according to manufacturer instructions and freeze until fully solid. Do not cut or puncture the cells.
Place insulating material. Line the bottom and sides of the cooler with an insulated panel to minimize thermal bridging.
Añadir capas de hielo seco. Place a layer of dry ice sheets above and below the medicine. Avoid direct contact between medicines and dry ice to prevent freezing damage.
Fill remaining space with cushioning material. Use foam or cardboard to prevent movement and maintain insulation.
Aventer el contenedor. Leave a vent or loose lid to allow CO₂ gas to escape; Los contenedores sellados pueden explotar..
Sello y etiqueta. Clearly mark the package with “Dry Ice” or “Carbon Dioxide, Solid” and indicate the weight. Include a description of the contents (p.ej., “vaccines”).
Temperatura de monitor. Use a data logger to track minimum and maximum temperatures during transit.
Cumplimiento normativo y seguridad
Límites de peso. For air shipments in the U.S., packages containing 2.5 kg (5.5 lb) or less of dry ice are exempt from hazardous material documentation. Packages over this limit require hazardous materials paperwork and adherence to IATA guidelines.
Ventilation and packaging integrity. Dry ice should never be shipped in airtight containers; venting prevents gas buildup that could cause explosions. Containers must withstand repeated loading and low temperatures.
Monitoreo de temperatura. Regulatory agencies recommend using a temperature monitoring device accurate to ±0.5 °C during transport. Record temperatures at the start and end of transport.
Vaccine specific guidance. The CDC advises against using dry ice to store vaccines temporarily because the extreme cold can damage many products. An exception exists for transporting ultra cold vaccines (p.ej., certain COVID 19 vaccines) that require dry ice.
