What are Dry Ice Packs and Dry Ice Bricks?

Gelo seco é dióxido de carbono sólido (Co₂) that sublimates at an extremely low temperature of -78.5°C (-109.3°F). It is used to maintain frozen and chilled conditions for temperature-sensitive goods during transport. Dry ice packs and dry ice bricks, while both effective in cooling, serve different purposes depending on the shipping requirements.

Pacotes de gelo seco

Dry ice packs are flexible, lightweight sheets that are often used for small to medium-sized shipments. They are typically filled with small pellets of dry ice and encased in materials like plastic or foam. Dry ice packs are ideal for short-duration shipping and can be easily arranged in packaging to fit various sizes.

Dry Ice Bricks

Dry ice bricks, por outro lado, are large blocks of dry ice that offer a more concentrated cooling effect. These are ideal for longer shipments, providing extended cooling durations. The rigid form of dry ice bricks allows for more stable temperature control during longer journeys.

How Do Dry Ice Packs and Dry Ice Bricks Maintain Cold Temperatures During Shipping?

Dry ice achieves its cooling power through sublimation, where it transitions from solid to gas without becoming liquid. This process absorbs heat, effectively lowering the surrounding temperature.

Sublimation Process and Cooling

• Pacotes de gelo seco: Sublimate at -78.5°C, providing moderate cooling for 24 para 48 horas. Their flexibility allows them to be easily distributed throughout the shipping container, maintaining consistent cold temperatures for smaller shipments.

• Dry Ice Bricks: Sublimate at the same temperature, but their larger mass and solid form cause them to release CO₂ gas at a slower rate, allowing them to maintain cold temperatures for longer, making them ideal for shipments lasting up to 72 horas ou mais.

Melhores práticas para usar gelo seco no envio

Embalagem adequada

• Isolamento: Use high-quality insulated boxes like Styrofoam or polyurethane foam to reduce heat transfer. Ensure the packaging allows for CO₂ gas to escape, as dry ice sublimates into gas.

• Ventilação: Dry ice must be packed in containers that allow the CO₂ gas to vent to avoid pressure buildup, which could lead to the rupture of packaging.

Calculating the Right Amount of Dry Ice

The quantity of dry ice required depends on factors such as the shipment’s duration, a qualidade do isolamento, and the ambient temperature during transport. Como regra geral, for a 24-hour shipment, 0.5 kg of dry ice per kg of the product should be used. Para durações mais longas, increase the amount of dry ice by 1.5 times to account for sublimation rates.

Rotulagem e documentação

When shipping with dry ice, it’s crucial to comply with regulatory requirements:

• Proper labeling with “Dry Ice” or “Carbon Dioxide, Solid”

• UN1845 shipping number

• Aula 9 Etiqueta de perigo

• The net weight of dry ice in kilograms

These labeling requirements are essential for ensuring safe and compliant transport.

Safety and Regulatory Compliance for Dry Ice Shipping

O gelo seco é classificado como um material perigoso (Aula 9, UN1845) and requires adherence to specific shipping regulations. Compliance with IATA (Associação Internacional de Transporte Aéreo) e ponto (Departamento de Transporte) guidelines is mandatory to ensure safe shipping.

Key Compliance Requirements:

1. Embalagem: Dry ice must be transported in vented packaging, such as corrugated cardboard boxes with foam insulation.

2. Documentação: Include a proper air waybill with the shipping details, including the weight of dry ice.

3. Manuseio: Always wear insulated gloves and safety goggles when handling dry ice to prevent injury from frostbite or eye exposure.

Gelo seco vs.. Pacotes de gel: Which Is Better for Your Shipment?

Dry ice is often compared to gel packs, especially for shipments that need to be chilled but not frozen. No entanto, dry ice has several advantages for specific needs:

Gelo Seco

• Extremely Low Temperatures: Dry ice can keep frozen goods solid, unlike gel packs, which are not designed for subzero temperatures.

• Duração mais longa: Dry ice bricks, em particular, provide longer cooling durations than gel packs.

Pacotes de gel

• Safer and Easier to Handle: Gel packs are non-toxic, reutilizável, and require no special handling. No entanto, they cannot achieve the ultra-low temperatures necessary for frozen goods.

• Shorter Cooling Period: Gel packs are ideal for chilled items but not suitable for extended freezing.

Environmental Impact and Sustainability of Dry Ice Shipping

Em 2025, sustainability is a key concern in the cold chain logistics industry. Dry ice offers some environmental advantages but also has its drawbacks.

Pros of Dry Ice:

• Reclamado co₂: Many suppliers produce dry ice from CO₂ captured during industrial processes, reduzindo as emissões.

• No Water Waste: Dry ice sublimates directly into gas, leaving no water residue and reducing waste.

Desafios:

• Liberação co₂: Although CO₂ is reclaimed, it is released into the atmosphere during sublimation.

• Energy Use: The production of dry ice requires energy, typically from non-renewable sources.

Sustainability trends include the use of biodegradable refrigerants, IoT-enabled temperature monitoring, and smart packaging solutions.

Perguntas frequentes (Perguntas frequentes)

Q1: Quanto tempo dura o gelo seco durante o envio?
Dry ice typically lasts between 18 para 72 horas, Dependendo do tipo (pack or brick), isolamento, e condições ambientais.

Q2: Can dry ice be used for international shipments?
Sim, Gelo seco pode ser enviado internacionalmente, but it must comply with international shipping regulations, including those set by IATA and DOT.

Q3: What are the safety precautions for shipping with dry ice?
Garanta ventilação adequada, use appropriate protective gear, and comply with all labeling and documentation requirements.
