Can You Combine Dry Ice and Gel Packs in One Shipment?

Are you looking to combine dry ice and gel packs in one shipment for transporting temperature-sensitive goods? The good news is that it’s not only possible but also highly effective when done correctly. Combining these two cooling methods can extend the shelf life of your products, provide versatile temperature control, and ensure safety throughout the journey. Dalam artikel ini, we’ll explain how to combine dry ice and gel packs for maximum efficiency, keamanan, and compliance with the latest regulations in 2025.

Apa yang Paket es kering dan gel?

What Is Dry Ice?

Es kering adalah karbon dioksida padat (Co₂) that sublimes directly from a solid to a gas at -78.5°C (-109.3° f). Its ultra-low temperature makes it an ideal cooling agent for keeping products frozen during transportation. Dry ice is used for shipping a variety of perishable goods, termasuk makanan, Farmasi, dan sampel biologis. Namun, due to its extremely cold temperature and the release of CO₂ gas during sublimation, handling dry ice requires caution.

Apa itu paket gel?

Gel packs are water-based cooling agents that freeze to a solid and maintain a moderate temperature (typically between 0°C and 5°C). Tidak seperti es kering, gel packs provide steady cooling and are often used to keep goods chilled but not frozen. Commonly employed for food, Persediaan medis, and delicate items, gel packs are non-toxic and safer to handle than dry ice. They are versatile and reusable, making them a popular choice in cold chain logistics.

Benefits of Combining Dry Ice and Gel Packs in One Shipment

How Does Combining Dry Ice and Gel Packs Help?

Combining dry ice and gel packs allows you to cater to different temperature requirements in the same shipment. This approach offers several distinct advantages:

Waktu pendinginan yang diperpanjang: Dry ice sublimes quickly, but gel packs can slow down this process. By using both, you can extend the total cooling duration, ensuring products stay within their desired temperature range for longer.
Kontrol suhu: For shipments containing both frozen and refrigerated items, combining dry ice and gel packs allows you to create a stable temperature environment, avoiding the risk of products freezing or overheating.
Efisiensi biaya: Using gel packs in combination with dry ice can reduce the amount of dry ice required, which can lower shipping costs while still maintaining proper temperature control.
Reduced Frostbite Risk: Paket gel, unlike dry ice, do not pose a frostbite hazard to handlers, making them a safer option for packaging and unpacking shipments.

How to Safely Pack Dry Ice and Gel Packs Together?

Packing Guidelines

Proper packaging is critical when combining dry ice and gel packs to ensure the safety and effectiveness of the cooling solution. Here’s how to pack them correctly:

Layering the Cooling Agents: Start by placing the gel packs near the products that need to be kept at a moderate temperature (0° C hingga 5 ° C.). Dry ice should be placed on top or in an outer layer, ensuring that it doesn’t come into direct contact with the products to prevent freezing.
Isolasi: Use high-quality insulated containers, such as Styrofoam boxes or vacuum-insulated panels (VIP), to keep the temperature stable. Insulation helps control the rate at which dry ice sublimates and extends its cooling time.
Ventilasi: Es kering sublimat ke dalam gas co₂, which can build up pressure in an airtight container. Ensure that the packaging is ventilated to allow the gas to escape safely. Jangan pernah menyegel es kering dalam wadah kedap udara, as this could lead to an explosion.
Moisture Barriers: Use moisture-absorbing materials such as poly bags or bubble wrap to prevent water from affecting the products due to condensation from the gel packs.

Packaging Example:

Packaging Step	Tindakan	Keuntungan
Layering	Place gel packs below, dry ice above	Maintains desired temperature
Isolasi	Use high-quality insulated containers	Extends cooling time
Ventilasi	Ensure ventilation holes for CO₂ gas	Prevents pressure build-up
Moisture Barrier	Use moisture-absorbing materials	Prevents product damage

Safety Considerations for Shipping with Dry Ice and Gel Packs

1. Ventilasi yang tepat

Saat es kering menyublim, it releases CO₂ gas. In confined spaces, this can lead to asphyxiation. Always ensure your packaging is vented properly to allow the gas to escape. Selain itu, dry ice can cause frostbite, so make sure to handle it with care.

2. Handling Protective Gear

Saat menangani es kering, wear insulated gloves, safety goggles, and long sleeves to prevent frostbite. While gel packs are safer to handle, they should still be managed according to the manufacturer’s instructions.

3. Packaging Materials

Ensure the materials used for packaging are strong enough to withstand the extreme cold of dry ice without breaking. High-quality, insulated containers made from Styrofoam or polyurethane are often recommended.

4. Labeling and Documentation

Shipments containing dry ice must be clearly labeled according to regulatory requirements. The package should be marked with the correct UN number (UN1845) and should include a warning about the presence of dry ice. If the shipment exceeds 2.5 kg es kering, it may require additional documentation and special handling instructions.

2025 Trends in Cold Chain Logistics and Temperature Control

As we approach 2025, the cold chain logistics industry is seeing significant changes in the ways temperature-sensitive goods are transported. Some of the latest trends include:

Kemasan Cerdas: With advancements in IoT and smart sensors, real-time monitoring of temperature and humidity during transport is becoming increasingly common. This enables businesses to track the conditions of their shipments and make adjustments when necessary.
Solusi Rantai Dingin Berkelanjutan: There is a growing focus on sustainability in the cold chain sector, with companies adopting eco-friendly materials and cooling solutions such as reusable gel packs and biodegradable dry ice alternatives.
Hybrid Coolant Systems: The combination of dry ice and gel packs, known as hybrid coolant systems, is gaining popularity as businesses look for ways to balance cost, efisiensi, dan keberlanjutan.

Common Questions About Combining Dry Ice and Gel Packs

Q1: Is it safe to use dry ice and gel packs together?
Ya, when done properly, combining dry ice and gel packs is safe. Just make sure to follow the recommended packaging guidelines and safety measures.

Q2: How do I prevent products from freezing when using dry ice and gel packs?
By placing gel packs near temperature-sensitive items and ensuring that dry ice is kept away from those items, you can prevent accidental freezing.

Q3: How long will dry ice and gel packs last in transit?
Es kering biasanya bertahan 24-48 hours depending on the quantity and packaging, while gel packs can maintain a moderate temperature for up to 3-5 hari -hari.

Kesimpulan dan Rekomendasi

Combining dry ice and gel packs in a single shipment is an effective strategy for controlling temperature during transport, especially for shipments with mixed temperature requirements. By following the proper safety protocols, packaging guidelines, dan peraturan, you can ensure that your products remain safe and in compliance with the latest standards.
