Saat mengirimkan barang yang sensitif terhadap suhu, the right refrigerant is crucial. Whether it’s dry ice or gel packs, each option has its strengths and weaknesses. This article will help you choose the best solution for shipments lasting 48 atau 72 jam, considering factors like cost, efektivitas, dan dampak lingkungan.
-
Es kering: Ideal for maintaining frozen conditions, with a cooling range of -109°F (-78° C.).
-
Paket gel: Perfect for moderate cooling (2–8 ° C.), effective for products that need to stay cool, but not frozen.
-
Hybrid Solutions: A combination of both can optimize temperature control.
What Are the Key Differences Between Dry Ice and Gel Packs for Long-Duration Shipments?
Dry ice and gel packs serve distinct purposes, and understanding their differences is crucial for determining which is best suited for your shipment. Below is a comparison based on key features:
| Fitur | Paket es kering | Paket gel |
|---|---|---|
| Kisaran suhu | -109° f (-78° C.) | 32° f (0° C.) |
| Durasi pendinginan | 24-72 jam (depending on quantity) | 24-48 jam (depending on size) |
| Biaya | Lebih tinggi | Lebih rendah |
| Dampak Lingkungan | CO₂ emissions | Biodegradable water-based gel |
| Terbaik untuk | Barang beku (farmasi, makanan) | Chilled goods (kosmetik, elektronik) |
Es kering: When is It the Right Choice?
Es kering provides ultra-low temperatures, making it ideal for products that need to remain frozen for extended periods. Proses sublimasi, which turns solid CO₂ directly into gas, menyerap panas, keeping the products at extremely low temperatures.
Keuntungan utama dari es kering:
-
Durasi pendinginan yang diperpanjang: Maintains freezing conditions for up to 72 hours with proper insulation.
-
Tidak ada residu cairan: Unlike gel packs, dry ice sublimates directly, leaving no moisture that could damage packaging.
-
Highly Effective for Deep-Freezing: Essential for products that need to remain frozen like vaccines, makanan beku, and lab samples.
Considerations:
-
Penanganan: Requires insulated gloves and safe handling due to the extremely low temperatures.
-
Kepatuhan Pengaturan: Larger shipments require special labeling and handling procedures under regulations like IATA.
Best Use Cases:
-
Farmasi: Medical products that require sub-zero temperatures.
-
Makanan beku: Ideal for keeping products like meats and ice cream frozen.
-
Sampel laboratorium: Scientific specimens that need freezing during transport.
Paket gel: When to Use Them?
Paket gel are designed to maintain a temperature range of 2–8°C, perfect for goods that need cooling but not freezing.
Key Advantages of Gel Packs:
-
Affordability: More cost-effective for shipments that don’t require extreme cold.
-
Non-Hazardous: Easy to handle and don’t require special equipment or ventilation.
-
Dapat digunakan kembali: Can be refrozen and reused, making them a more sustainable option.
Considerations:
-
Durasi pendinginan: Gel packs typically last only 24-48 hours and might not be suitable for longer shipments.
-
Kondensasi: When they thaw, condensation can form and potentially cause damage if not managed properly.
Best Use Cases:
-
Makanan yang mudah rusak: Ideal for shipments of fresh produce or dairy products.
-
Kosmetik: Many cosmetics require cool storage but not freezing.
-
Elektronik: To protect sensitive electronics from heat damage.
Combining Dry Ice and Gel Packs for Longer Shipments
For shipments approaching the 72-hour mark, combining both dry ice and gel packs can offer a balanced solution. By placing gel packs around the perimeter and dry ice in the center, you can ensure that the center remains frozen while the edges stay cool, preventing any items from freezing unnecessarily.

Sustainability in Packaging:
The cold chain industry is leaning towards more sustainable solutions. Paket gel are becoming increasingly popular due to their biodegradable nature, ketika es kering production is being enhanced to reduce CO₂ emissions through new methods like carbon-negative dry ice production.
Innovations in Temperature-Controlled Shipping:
New technologies such as phase-change materials (PCMS) Dan smart ice sensors are revolutionizing cold chain logistics. These advancements allow for more precise control and tracking of temperatures during transit, ensuring that temperature-sensitive goods are shipped more efficiently.
Pertanyaan yang sering diajukan
Q1: Can dry ice be used for medical shipments?
Ya, dry ice is perfect for medical shipments that require freezing conditions. It’s widely used for transporting vaccines, blood, and other medical supplies.
Q2: How long do gel packs last in transit?
Gel packs typically last 24-48 jam, depending on the size and insulation used. They’re best for products that need to stay cool but not frozen.
Q3: Are gel packs eco-friendly?
Ya, gel packs are made from water-based materials and are biodegradable, making them a more environmentally friendly option compared to dry ice.
Kesimpulan
When deciding between dry ice and gel packs for your 48-72 hour shipments, consider the nature of your product and the temperature it requires. Dry ice is ideal for freezing conditions, while gel packs are suitable for products that need to stay cool but not frozen. Always weigh the cost, handling requirements, and environmental impact of each option.
