Saat mengirimkan barang yang sensitif terhadap suhu, es kering sering kali merupakan solusi pendinginan untuk. Tetapi how long do dry ice packs last? Apakah itu 24, 48, atau 72 jam? The answer depends on several variables like the amount of dry ice used, the quality of insulation, and the environmental conditions during transit. Dalam panduan ini, we’ll break down the factors that influence dry ice lifespan, give you best practices to optimize its duration, and help you decide when dry ice is the right choice for your shipment.

What factors determine whether a dry ice pack lasts 24, 48, atau 72 jam?
-
How much dry ice should you use, and how does insulation affect its longevity?
-
When should you consider using gel packs or phase change materials (PCMS) bukannya es kering?
-
Apa 2025 regulations and safety rules apply to dry ice shipments?

How do new technologies extend dry ice hold times?
What Affects the Duration of Dry Ice Packs?
Why Does Dry Ice Duration Vary So Much?
Sublimat es kering (mengubah dari padat menjadi gas) pada -78,5 ° C.. Several factors control the sublimation rate:
-
Jumlah es kering: More dry ice equals longer cooling durations. Umumnya, 5–10 pounds of dry ice sublimate every 24 hours under standard conditions.
-
Packaging and Insulation: Well-insulated containers slow down the heat transfer into the box, preventing rapid sublimation.
-
Suhu sekitar: Iklim yang lebih panas menyebabkan es kering menyublim lebih cepat. If the shipping route passes through warm areas, more dry ice and better insulation are required.
Estimated Durations Based on Conditions:
| Jumlah es kering | Perkiraan Durasi |
|---|---|
| 5–10 lbs | Hingga 24 jam |
| 8–10 lbs | Hingga 48 jam |
| 10–15 pon | Hingga 72 jam |
Untuk tipnya: Always plan for a buffer—add 10-25% more dry ice to cover unexpected delays or temperature fluctuations.
How Much Dry Ice Is Required?
How Do You Calculate Dry Ice Needs?
To determine how much dry ice you’ll need, consider the following guidelines:
-
For 24-Hour Shipments: 5-10 pon es kering sudah cukup.
-
For 48-Hour Shipments: Double the amount of dry ice (10-20 pound).
-
For 72-Hour Shipments: Merencanakan 20-30 Es kering, especially if shipping in warmer climates.
The Role of Packaging and Insulation
Packaging Types for Dry Ice:
-
Standard Dry Ice Bags: Good for short shipments (24-48 jam) but may not provide long-lasting cooling.
-
Foil-Lined Bags: Provide better insulation for longer trips (48-72 jam).
-
Kotak terisolasi: Ideal for shipments requiring temperature control over extended periods, such as pharmaceutical products.
Tip: Always choose the right packaging for your shipment’s duration and temperature requirements.
Should You Switch to Gel Packs or PCMs?
While dry ice is ideal for freezing temperatures, alternative solutions like gel packs and phase change materials (PCMS) are becoming increasingly popular.
When to Use Alternatives:
-
Paket gel: Best for products that need to remain cool (2-8° C.) tapi tidak beku.
-
PCMS: Suitable for shipments requiring consistent cooling but not extreme low temperatures. These materials are non-hazardous and reusable, offering a more sustainable solution.
Es kering vs.. Alternatif:
| Fitur | Es kering | Paket gel | PCMS |
|---|---|---|---|
| Suhu | ≤ -78.5°C | 2° C hingga 8 ° C. | Bervariasi (typically 2–8°C) |
| Lamanya | 24–72 jam | 12–48 jam | Hingga 72 jam |
| Biaya | Sedang | Rendah | Moderate to High |
| Terbaik untuk | Barang beku | Refrigerated items | Temperature-sensitive goods |
Untuk tipnya: When shipping ultra-sensitive items like vaccines, consider using PCMs for better stability and regulatory compliance.
2025 Tren pengiriman es kering
The dry ice shipping industry is evolving in response to new regulations, sustainability concerns, and technological advances.
Kunci 2025 Tren:
-
Kemasan Cerdas: Temperature sensors and IoT devices are becoming standard in shipments, providing real-time monitoring of dry ice levels and temperatures.
-
Keberlanjutan: Biodegradable and recyclable materials are gaining traction, offering a greener alternative to traditional dry ice packaging.
-
Solusi Pendinginan Hibrida: Combining dry ice with PCMs to maintain temperature stability for extended periods.
Pertanyaan Umum
Berapa banyak es kering yang saya butuhkan untuk pengiriman 24 jam?
Untuk pengiriman 24 jam, khas 6-7 pounds of dry ice is required in an EPS liner or 4-5 pounds in a VIP system.
Can dry ice keep products frozen for 72 jam?
Ya, but you’ll need 15-30 Es kering, depending on insulation and ambient temperatures.
When should I use PCM or gel packs instead of dry ice?
For shipments under 72 hours that require temperatures between 2-8°C, PCM or gel packs are ideal. Dry ice is necessary for deep freeze conditions.
Kesimpulan dan Rekomendasi
Understanding how long dry ice lasts is crucial for ensuring the safe transport of perishable goods. The longevity of dry ice packs depends on factors like the amount of dry ice used, packaging quality, dan kondisi lingkungan.
Langkah Tindakan:
-
Assess your shipment’s needs based on travel duration and product sensitivity.
-
Choose the appropriate packaging to match your shipment’s duration.
-
Plan for sufficient dry ice and consider alternatives like PCMs or gel packs if freezing temperatures aren’t necessary.
Dengan mengikuti langkah -langkah ini, you can ensure your products stay at the right temperature during transit, optimize shipping costs, and maintain compliance with industry regulations.
