What Are Dry Ice Packs and How Do They Work?

Dry ice packs are sealed containers filled with solid carbon dioxide (Co₂), which sublimate from a solid directly into a gas without turning into a liquid. This unique characteristic makes dry ice a superior cooling agent compared to regular water ice. At a chilling temperature of −109.3°F (−78.5 ° C.), dry ice ensures that goods stay frozen without leaving any residual water, making it ideal for shipping frozen food, Spesimen Biologis, dan obat -obatan.

Why Choose Dry Ice for Shipping?

• Cold Storage for Long Durations: Tidak seperti es biasa, yang meleleh ke dalam air, dry ice remains solid and cools goods for up to 72 jam, making it ideal for long shipments.

• No Mess: Dry ice turns into gas, avoiding the liquid residue that can damage packaging or goods.

• Higher Efficiency: Dry ice maintains a sub-zero temperature, ensuring perishable items stay frozen throughout their journey.

How Does Dry Ice Work?

• Sublimation: Sublimat es kering (turns directly into gas), which releases CO₂ into the air. This prevents the buildup of water, which can affect the quality of the product, especially for items like frozen meat or medications.

• Suhu: Dry ice maintains an extremely low temperature (−109.3°F or −78.5°C), much colder than regular ice, which freezes at 32°F (0° C.). This ensures products stay frozen or remain at optimal cold storage temperatures during shipping.

How to Handle Dry Ice Safely?

Handling dry ice requires extra caution due to its extremely low temperature and the CO₂ gas it emits during sublimation. Follow these essential safety steps:

• Kenakan perlengkapan pelindung: Always use insulated gloves and safety goggles to handle dry ice, karena kontak langsung dapat menyebabkan radang dingin yang parah.

• Pastikan ventilasi yang tepat: Since dry ice releases CO₂ gas, always handle it in well-ventilated areas to prevent oxygen displacement, which can lead to suffocation in confined spaces.

• Avoid Airtight Containers: Never seal dry ice in airtight containers because the buildup of CO₂ gas can cause the container to rupture.

Handling Tips for Maximum Safety:

• Ventilate the Area: Ensure the room where you handle dry ice is ventilated, allowing the gas to escape safely.

• Use in Moderation: Calculate the appropriate amount of dry ice based on the shipment duration and product temperature requirements. Excessive use can result in dangerous CO₂ buildup.

• Storage in Open Spaces: Avoid storing dry ice in small, confined spaces like cars or walk-in coolers, where the gas could accumulate and displace oxygen.

Es kering vs.. Paket gel: Which Is Best for Your Needs?

When deciding whether to use dry ice packs or gel packs, it depends on the type of shipment, kisaran suhu yang diperlukan, and the duration of transport.

• Es kering: Best for long-duration shipments (48-72 jam) that require sub-zero temperatures, such as frozen meats, vaksin, dan sampel biologis.

• Paket gel: Ideal for shorter durations and products that need to stay chilled but not frozen, such as fresh food or certain medications.

Key Comparison:

How to Calculate the Right Amount of Dry Ice for Your Shipment

To determine the correct amount of dry ice, several factors must be considered, including shipment duration, product type, and the insulation quality of your packaging. Khas, dry ice is used in quantities of 5–10 lbs per 24 jam.

General Guidelines:

1. For 24-hour shipments: Use 5–10 lbs of dry ice.

2. For 48-hour shipments: Use 10–20 lbs of dry ice.

3. For 72-hour shipments: Use 15–30 lbs of dry ice.

Adjusting for Conditions:

• Higher Temperatures: Add an extra 10-15% dry ice to account for faster sublimation in hot weather.

• Better Insulation: If you use thicker insulation, you may need less dry ice.

Dry Ice Regulations for Shipping

Shipping dry ice is regulated to ensure safety for handlers and the environment. Compliance with regulations is critical when preparing shipments.

Key Regulations:

• Pelabelan: Packages containing dry ice must be labeled with “Dry Ice” or “Carbon Dioxide, Solid” along with the UN1845 marking.

• Quantity Limits: Untuk pengiriman udara, the maximum dry ice allowed per package is typically 5.5 lbs (2.5 kg), depending on the carrier.

• Ventilasi: Packaging must allow CO₂ gas to escape. Ensure that containers are vented appropriately.

Best Practices for Storing and Handling Dry Ice

Dry ice must be stored and handled correctly to prevent accidents and ensure its effectiveness during transport.

Storage Tips:

• Gunakan wadah terisolasi: Store dry ice in a vented cooler or insulated box to reduce sublimation while allowing gas to escape.

• Keep in a Cool, Dry Area: Store dry ice in a cool, dry space to minimize sublimation, but avoid airtight containers that could cause pressure buildup.

Additional Tips:

• Buy Only What You Need: Dry ice sublimates quickly, so only purchase the amount necessary for the shipment to avoid waste.

• Use a Thermometer: Consider using temperature data loggers to monitor the temperature of your goods during transport, ensuring they stay within safe ranges.

2025 Trends in Dry Ice Usage for Shipping and Logistics

The cold chain logistics sector is increasingly integrating technology into packaging solutions, improving efficiency and reliability.

Perkembangan terbaru:

• Kemasan Cerdas: Temperature-sensitive monitoring technologies, such as smart labels and Bluetooth-enabled temperature sensors, help track the condition of shipments in real-time.

• Keberlanjutan: The industry is moving towards more eco-friendly alternatives, including reusable phase-change materials that reduce reliance on dry ice.

Wawasan pasar:
