How Do Disposable Dry Ice Packs Work and Why Choose Them Over Gel Packs?
Dry ice packs use sublimation to deliver ultracold temperatures without creating moisture. Each pack encases solid carbon dioxide pellets that turn directly into gas at –78.5 °C. As the dry ice absorbs heat from your shipment, it keeps goods frozen for 24–72 horas dependiendo del tamaño y el aislamiento del paquete. En comparación, gel packs maintain 2–8 °C for up to 48 hours and often leak water as they thaw. Porque el hielo seco se sublima, packages stay dry and there’s no risk of condensation or soggy products.
For shippers of frozen meat, mariscos, vacunas y biológicos, disposable dry ice packs are invaluable. Ellos proporcionan temperaturas ultrabajas—as low as –78,5 ºC—that gel packs cannot achieve. This makes them the preferred choice for longdistance shipments or routes through warm climates. While dry ice requires special handling and labeling as a hazardous material, its performance and leakfree design deliver reliable, consistent cooling for highvalue products.
Temperature Range and Duration Comparison
The table below highlights the key differences between common refrigerants. Use it to select the right pack for your shipment.
| Método de enfriamiento | Rango de temperatura | Duración típica | Implicaciones prácticas |
| Mini capa de hielo seco | –78,5 °C a –18 °C | 24–48 H | Ideal para productos farmacéuticos o biológicos que requieren temperaturas ultrabajas constantes; avoids moisture and is suitable for shorttomedium distances. |
| Paquete de hielo seco desechable | –78,5 ºC | Arriba a 72 h | Perfecto para envíos de carne congelada a larga distancia, mariscos o vacunas; singleuse convenience and no melting water. |
| Paquete de gel (2–8 ° C) | 2 °C-8 °C | Arriba a 48 h | Mantiene los productos, Los lácteos o medicamentos se enfrían sin congelar.; reusable but may leak water and cannot maintain deepfreeze temperatures. |
| Paquete de agua tradicional | ≈0°C | 24–36 horas | Cheap solution for short journeys; riesgo limitado de fuga de humedad y masa térmica. |
Consejos prácticos y recomendaciones
Hidratarse y congelarse adecuadamente: Activate disposable dry ice sheets by hydrating the polymer cells and freezing for at least 24 horas.
Preenfriar sus productos: Freezing or chilling goods before packing reduces the heat load and extends cooling duration.
Utilice sábanas más grandes para viajes más largos: Bigger packs contain more CO₂ and last longer.
Seleccione el diseño correcto: Place dry ice on top of your goods to allow cold air to sink and ensure uniform cooling. Para viajes largos, use hybrid layouts with dry ice around the sides and combine with phasechange materials (PCM).
Temperatura de monitor: Emplee registradores de datos o sensores de IoT para rastrear las temperaturas internas y ajustar los números de paquetes en consecuencia.
Ejemplo del mundo real: Una empresa farmacéutica que envía 8 lb of frozen vaccine vials from Los Angeles to Chicago uses an 8 lb disposable dry ice pack and adds 30 % extra dry ice during peak summer. By prefreezing the vials to –20 °C and using a hybrid layout with vacuuminsulated panels, the shipment stays below –70 °C for 72 horas.
How to Choose and Size Disposable Dry Ice Packs for Your Shipment
Selecting the right dryice pack size depends on product weight, tiempo de tránsito, calidad del recorrido y aislamiento. Una simple regla general es una 1:1 Relación entre el peso del hielo seco y el peso del producto. para envíos en 48 horas. If you’re shipping 8 libra de mariscos congelados, empezar con 8 libra de hielo seco. Adjustments are necessary for seasonal temperatures (add 25–35 % more dry ice in summer), complex routes (add 10–15 % for multihandoff lanes) and improved insulation (reduce by 10–25 % when using vacuum panels).
Estrategias de tamaño y diseño
Follow these guidelines to optimize pack performance:
Assess product weight and temperature requirements: Determine how cold your shipment must stay (–70 °C for vaccines, –20 °C for frozen food, 2–8 °C for refrigerated items). Use higher weight ratios for ultracold shipments.
Consider route complexity and duration: Add extra dry ice when shipping across multiple hubs or when delays are likely.
Upgrade insulation for efficiency: Vacuuminsulated panels reduce dry ice requirements by 10–25 %, ahorro de peso y coste. Even simple improvements like foam pads or crumpled paper to fill voids can reduce sublimation.
Utilice paquetes híbridos: Combining dry ice with PCMs buffers temperature fluctuations and extends duration to 72 horas o más. Hybrid layouts place dry ice on top and PCMs around the sides.
Plan for preconditioning: Freeze products below –18 °C and chill packaging materials before assembly. Doing so reduces initial heat loads and lengthens cooling time.
Seguridad, Consideraciones regulatorias y de manejo
El hielo seco es extremadamente frío y está clasificado como material peligroso. (Y 1845), por lo que el manejo adecuado es esencial. Utilice siempre guantes aislantes y protección para los ojos.—direct skin contact can cause frostbite. Porque el hielo seco se sublima en gas dióxido de carbono, never seal it in an airtight container; venting prevents pressure buildup and oxygen displacement. Al transportar hielo seco, keep the vehicle well ventilated and avoid enclosed spaces.
Regulatory agencies like the International Air Transport Association (IATA), Estados Unidos. Departamento de Transporte (PUNTO) and national post services have specific guidelines. Packages containing dry ice must display a Class 9 hazard label and indicate the net weight. Airlines often limit dry ice quantities to 5 kg por paquete y requieren la documentación adecuada. Training staff and providing clear handling instructions to customers reduces risks and ensures compliance.
Safe Handling and Storage Tips
Use equipo de protección: Usa guantes gruesos, safety goggles and long sleeves to avoid skin contact.
Proporcionar ventilación: Keep shipping containers vented and never store dry ice in sealed cellars or car trunks.
Etiqueta y documento: Display UN 1845 etiquetas, mark the net weight and provide Material Safety Data Sheets (MSDS) or safety instructions to recipients.
Responder a la congelación: Si se produce contacto, Retire la ropa que no esté congelada sobre la piel y sumerja el área en agua tibia. (abajo 40 °C) water—do not rub the affected area.
Monitorear los niveles de CO₂: In storage rooms or staging areas, use CO₂ monitors to prevent buildup.
Impacto ambiental y alternativas sostenibles
Dry ice is carbon dioxide in solid form and releases CO₂ gas as it sublimates. This greenhouse gas contributes to climate change if not managed properly. Sin embargo, most industrial dry ice is produced from recycled CO₂ captured during processes like ammonia synthesis and ethanol production. Recycling repurposes waste CO₂ and reduces the need for virgin fossil fuels. To mitigate the environmental impact:
Use dry ice produced from recycled CO₂.
Optimize quantity and packaging: Efficient use reduces the amount of CO₂ released. Using vacuuminsulated panels or hybrid packouts cuts the total dry ice required.
Capture and recycle CO₂: Las tecnologías emergentes capturan CO₂ sublimado y lo reutilizan en invernaderos o en la carbonatación de bebidas..
Combine with sustainable materials: Manufacturers are developing recyclable thermal shippers and gel packs with biodegradable polymers. Hybrid solutions using PCMs extend cooling duration and reduce dry ice consumption.
The table below compares dry ice with two greener alternatives.

Tips to Reduce Environmental Impact
Choose recycled sources: Ask suppliers for dry ice produced from captured CO₂.
Usa solo lo que necesitas: Follow sizing guidelines and adjust for season and route to minimize excess CO₂ release.
Adopt hybrid packouts: Combine dry ice with PCMs or ecofriendly gel packs to reduce total dry ice consumption.
Educar a los destinatarios: Provide disposal instructions and encourage reuse of packaging materials.
Sustainability case: A mealkit company replaced singleuse EPS foam and heavy gel packs with hybrid dry ice/PCM kits packaged in recyclable cardboard. By using only the amount of dry ice needed and selecting biodegradable PCM packs, reducen las emisiones del transporte marítimo en 20 % y recibió comentarios positivos de clientes conscientes del medio ambiente.
