Does a Dry Ice Bag Work Better Than Gel Packs for Cold Chain Shipping?

Ketika datang untuk pengiriman produk yang sensitif terhadap suhu, selecting the correct refrigerant is crucial for maintaining product quality and complying with 2025 shipping regulations. Does a dry ice bag work better than gel packs? The answer depends on your shipment’s specific temperature requirements, lamanya, and regulatory compliance needs. Dalam artikel ini, we’ll guide you through the best practices for choosing between dry ice bags and gel packs, ensuring your shipments stay cold or frozen as required while meeting all regulatory standards.

• Choose the right cold source based on temperature requirements and transit time (MISALNYA., “dry ice for 48-hour frozen shipping”).

• Navigate the latest 2025 air transport regulations (Ini pi 954, UN1845, venting requirements).

• Estimate cooling capacity with easy-to-understand energy math for dry ice versus gel packs.

• Optimize packouts to reduce touchpoints and chargeable weight, ensuring cost-effective shipping.

Does a Dry Ice Bag Work Better Than Gel Packs for Keeping Items Frozen?

For shipments requiring temperatures of -20°C or lower, a dry ice bag is generally the best option. Es kering, at -78.5°C, sublimates and absorbs a large amount of heat, ensuring that frozen goods stay solid over extended periods. This is crucial for shipping items like ice cream, daging beku, or certain medical specimens. Di sisi lain, Paket gel, which maintain a temperature near 0°C, are ideal for short-term refrigeration (2-8° C.) but fail to maintain deep-freezing temperatures for long durations. Karena itu, dry ice bags are superior for long-distance frozen shipments, especially when maintaining ultra-cold temperatures for up to 48 hours or longer.

Why Dry Ice Bags Excel in Frozen Shipments

Dry ice provides significant cooling capacity due to its low temperature and sublimation process. A kilogram of dry ice can absorb significantly more heat than a gel pack of the same weight, offering better performance, especially in extreme conditions. Dry ice is particularly effective in hot or extended transit routes where maintaining a frozen state is crucial.

Example Case: A seafood supplier used dry ice bags in place of gel packs for 48-hour summer shipments. Sebagai akibat, frozen core temperatures remained stable, complaints about thawing reduced, and delivery times improved.

Dry Ice Bags vs Gel Packs: Perbedaan utama

1. Kisaran suhu: Dry ice keeps products frozen, while gel packs maintain refrigeration but do not keep items frozen.

2. Durasi pendinginan: Es kering bertahan lebih lama, hingga 3 days or more depending on insulation, while gel packs typically last 24 jam.

3. Safety and Handling: Dry ice is classified as a hazardous material due to CO₂ release and extreme cold. Gel packs are non-hazardous and simpler to handle.

When to Choose Gel Packs Over Dry Ice Bags?

Gel packs are an excellent option for shipments requiring temperatures between 2°C and 8°C (didinginkan), such as biologics, chocolates, or certain pharmaceutical products. They are also ideal for short-duration shipments, especially those that need to stay chilled overnight or for a couple of days. Gel packs are cost-effective, dapat digunakan kembali, and have fewer regulatory hurdles compared to dry ice.

Why Gel Packs Are Often the Better Choice

• Simplicity: Gel packs are easy to use, with no need for special ventilation or hazardous material handling.

• Efektivitas biaya: They are cheaper for short-term or regular shipments.

• Reusability: Gel packs can be reused multiple times, making them a sustainable choice for businesses that regularly ship temperature-sensitive goods.

Key Advantages of Gel Packs:

• No special labeling or handling required.

• Lower upfront and operational costs for regular use.

• Ideal for items that should not freeze, like vaccines and fresh produce.

How to Choose Between Dry Ice Bags and Gel Packs for Your Shipments

Making the right choice involves considering your shipment’s temperature requirements, lamanya, and compliance needs. Here’s how you can quickly decide:

1. For Long, Deep-Freezing Shipments (≤ -20°C):

   • Kantong es kering are the better choice.

   • Ideal for shipments lasting 24-48 jam atau lebih.

   • Comply with IATA’s regulations (Dan 1845, Pi 954).

2. For Short, Refrigerated Shipments (2-8° C.):

   • Paket gel are perfect.

   • Suitable for 1-2 day shipments, such as meal kits or pharmaceuticals.

   • Lebih mudah ditangani, no special regulations, dan hemat biaya.

Compliance Considerations for 2025

Di dalam 2025, air transport regulations are stricter, especially when shipping hazardous materials like dry ice. Dry ice shipments must comply with IATA’s PI 954 Pedoman, including proper labeling and venting. For gel packs, there are fewer regulations to follow, making them simpler for international and domestic shipments.

Key Regulatory Requirements for Dry Ice Shipments (2025):

• Vented packaging is mandatory to allow CO₂ to escape.

• Labels must include “Dry Ice,” “Carbon dioxide, padat,” and the net weight.

• A Class 9 hazard label must be applied.

Paket gel are non-hazardous and do not require such extensive labeling or special handling.

Cost and Sustainability Considerations

While dry ice provides superior cooling performance, it comes with higher costs. Dry ice is single-use and must be purchased for each shipment, which can add up over time, especially for businesses with high-volume cold chain needs. Sebaliknya, Paket gel dapat digunakan kembali, making them more economical in the long run. Namun, gel packs contribute to plastic waste if not properly disposed of or recycled.

Sustainability Tip: Opt for recyclable or drain-safe gel packs to reduce environmental impact.

2025 Tren Pengiriman Rantai Dingin

Looking ahead to 2025, more businesses are exploring sustainable and efficient cold chain solutions. Permintaan untuk Bahan perubahan fase (PCM) is growing as they offer an eco-friendly alternative to dry ice and gel packs. PCM packs can maintain temperatures similar to dry ice without the same regulatory challenges and environmental concerns. Selain itu, Kemasan yang dapat didaur ulang Dan Solusi Pengemasan Cerdas are expected to play a larger role in optimizing cold chain logistics.

Future Directions:

• Sustainable PCM solutions: These offer a green alternative, with reusability and precise temperature control.

• Smart tracking and IoT: Real-time temperature monitoring and tracking will be integrated into packaging to provide more reliable cold chain solutions.
