Ao enviar produtos perecíveis, maintaining a stable temperature is critical to ensuring product integrity. Pacotes de gelo seco, feito de dióxido de carbono sólido (Co₂), offer a powerful solution to keep items frozen during transit. As the cold chain logistics industry evolves in 2025, understanding the latest regulations, best practices, and innovative trends in using dry ice for shipping is crucial for compliance and safety.
O que são Pacotes de gelo seco para envio?
Dry ice packs are sheets, blocos, or pellets of solid CO₂, designed to keep temperature-sensitive products at ultra-low temperatures. Unlike conventional ice, dry ice sublimates directly into gas without leaving behind any liquid residue. This feature makes it ideal for shipping items that require freezing, como produtos farmacêuticos, amostras biológicas, and certain perishable foods.
Why Use Dry Ice for Shipping?
Dry ice packs are an excellent choice for shipping due to their unique properties, providing several advantages over traditional cooling methods.
-
Long-Lasting Cooling Power: Dry ice sublimates at a much slower rate than regular ice, ensuring your goods remain cold for longer durations.
-
No Moisture Runoff: Since dry ice does not melt into water, there’s no risk of water damage to sensitive items.
-
Ideal for Extended Transit: Para remessas que duravam mais do que 48 horas, dry ice is often the preferred choice for keeping goods frozen.
2025 Regulations for Shipping Dry Ice
Shipping dry ice is subject to strict regulations due to its classification as a hazardous material. Em 2025, the following key regulations must be adhered to when shipping dry ice:
-
Número da ONU: Packages containing dry ice must be clearly labeled with the UN number “1845.”
-
Aula 9 Hazard Label: Uma aula 9 hazardous materials label must be affixed to the package.
-
Declaração de peso: The net weight of dry ice in kilograms must be marked on the package.
-
Venting Requirements: Packaging must allow CO₂ gas to escape to avoid pressure buildup during sublimation.
Para transporte aéreo, A Associação Internacional de Transporte Aéreo (IATA) limits the amount of dry ice per package to 2.5 kg on passenger aircraft and up to 200 kg on cargo flights.
Melhores práticas para usar pacotes de gelo seco no envio
To ensure the safe and efficient use of dry ice for shipping, Siga estas melhores práticas:
1. Selecione a embalagem apropriada
-
Recipientes Isolados: Use insulated coolers or Styrofoam containers to maintain the desired temperature.
-
Embalagem ventilada: Ensure the container has ventilation holes to allow CO₂ gas to escape during sublimation.
-
Cushioning: Properly secure items inside the packaging to prevent damage during transit.
2. Calculate the Amount of Dry Ice
Determine the quantity of dry ice based on the transit duration and the perishability of the goods. A common guideline is to use 2.5 kg of dry ice for every 24 horas de envio.
3. Label Packages Correctly
-
Mark the package clearly with “Gelo Seco” ou “Dióxido de carbono, Solid.”
-
Attach the Número da ONU (1845) e Aula 9 Hazard Label.
-
Specify the net weight of dry ice in kilograms.
Erros comuns para evitar
-
Sealed Containers: Never use airtight containers to pack dry ice; this can cause dangerous pressure buildup.
-
Rotulagem incorreta: Ensure all required labels are attached to avoid delays or rejections by shipping carriers.
-
Exceeding Weight Limits: Stick to the weight regulations to prevent violations of hazardous materials rules.
Alternatives to Dry Ice
Enquanto o gelo seco é eficaz, several alternatives may be more suitable depending on your shipment requirements:
-
Pacotes de gel: Reusable and non-hazardous, ideal for shorter transit times.
-
Materiais de mudança de fase (PCMs): These materials maintain specific temperature ranges and are reusable, offering a more sustainable option.
-
Pacotes de gelo tradicionais: While cheaper, ice packs can leave water residue, potentially damaging goods.
Sustainability and Trends in Dry Ice Shipping
Em 2025, several emerging trends are shaping the dry ice shipping industry, focused on both environmental sustainability and technological advancements.
1. Sustainable Dry Ice Production
Many suppliers are shifting toward environmentally friendly production methods by capturing CO₂ from industrial processes, such as ammonia synthesis, reducing the overall carbon footprint of dry ice.
2. Hybrid Packaging Solutions
Hybrid solutions combining dry ice and PCMs are gaining popularity. These packouts minimize CO₂ use while extending the cooling duration, making them more eco-friendly.
3. Smart Packaging and Tracking Technology
Innovations such as smart CO₂ sensors and QR-coded labels allow for real-time tracking of dry ice and product temperatures, ensuring better monitoring and compliance.
How to Store Dry Ice Packs for Shipping
Proper storage is essential to maximize the shelf life and effectiveness of dry ice packs:
-
Store in an Insulated Container: Use coolers or specially designed containers to slow sublimation.
-
Avoid Sealed Containers: Never store dry ice in airtight or sealed containers; always ensure proper ventilation.
-
Monitor Sublimation Rates: Keep track of the rate at which dry ice sublimates to ensure the correct temperature is maintained.
Frequently Asked Questions About Dry Ice for Shipping
Q1: Quanto tempo dura o gelo seco durante o envio?
