Dry Ice Packs for Cooler: How to Keep Items Frozen for Days

If you’re looking to keep items frozen for up to 72 jam, dry ice packs for cooler are the ideal solution. Dry ice maintains ultra-cold temperatures, making it perfect for preserving perishables or shipping temperature-sensitive items. This guide will cover everything you need to know about dry ice, from how it works to how to pack it safely for optimal performance.

Dry Ice Packs for Cooler

  • What are the best dry ice packs for coolers for 24–72 hour trips?

  • How much dry ice should you use in your cooler for 48–72 hours?

  • What are the essential packing steps for safe dry ice transport?

  • How do you safely handle and dispose of dry ice during your trip?

  • What are the latest 2025 regulations for using dry ice for shipping?


What Are Dry Ice Packs for Coolers and How Do They Work?

Direct Answer:
Dry ice packs for cooler are solidified carbon dioxide (Co₂) that provide ultra-cold temperatures through sublimation (turning from solid to gas). Tidak seperti es biasa, dry ice maintains temperatures much lower, making it perfect for keeping items frozen, even over extended periods.

Why Dry Ice Works:
Dry ice has a temperature of −78.5°C (−109.3 ° F.), significantly colder than regular ice, yang meleleh pada 0 ° C (32° f). This makes dry ice more effective for maintaining sub-zero temperatures, especially during longer trips or shipments. If you need to keep your contents at −20°C (−4°F) or lower for hours or days, Es kering adalah pilihan terbaik.

Es kering vs.. Regular Ice in Coolers:

Type of Ice Suhu Tahan waktu Manfaat utama
Es kering −78.5 ° C. (−109.3 ° F.) Hingga 72 jam Maintains ultra-low temperatures, no water mess
Es biasa 0° C. (32° f) 1–2 hari Easier to find, lower cost but melts faster

How Much Dry Ice Do You Need for Your Cooler?

Direct Answer:
The amount of dry ice required depends on several factors, including the cooler’s insulation, the type of items being transported, and the duration of your trip. A good guideline is to use 5–10 pounds of dry ice per day for a well-insulated cooler. For a 72-hour period, you’ll need approximately 15–30 pounds of dry ice.

Why This Matters to You:
Cooler insulation plays a key role in extending dry ice life. A high-quality cooler, such as one made with polyurethane foam or vacuum insulation panels (VIP), will prevent heat from entering, thus extending the sublimation time of dry ice. Selain itu, the surrounding environment temperature affects the rate at which dry ice sublimates.

Quick Calculation for 72-Hour Dry Ice Shipping:

Es kering (lb) = Daily Rate × Days × Safety Margin (1.15 ke 1.25)

Contoh: 8 lb/day × 3 days × 1.20 ≈ 29 lb (≈13.2 kg)

Tipe yang lebih keren Isolasi Dry Ice Use Typical Hold Time Apa artinya ini bagi Anda
EPS Coolers Sedang (1–1.5″) 5–10 lb/hari 48–72 jam Terjangkau, best for shorter trips
VIP Coolers Tinggi (0.5–1″) 3–6 lb/day 72+ jam Longer hold time with lower dry ice usage

Panduan langkah demi langkah: Cara mengemas pendingin dengan es kering

Direct Answer:
Proper packing is essential to ensure your dry ice packs for cooler will maintain low temperatures for as long as possible. Key steps include layering dry ice, ensuring proper venting, and sealing the cooler in a way that allows gas expansion.

Steps for Packing:

  1. Prefreeze Your Items:
    Ensure all items are frozen before packing. Dry ice is most effective when it starts with cold or frozen contents.

  2. Use a Vented Cooler:
    Select a cooler with ventilation or leave space for CO₂ gas to escape. Without venting, pressure can build up, which is dangerous.

  3. Layer Your Dry Ice:
    Place dry ice at the top or bottom of the cooler. Dry ice should generally go on top of the items, Saat udara dingin tenggelam.

  4. Leave Space for Gas Expansion:
    Don’t pack dry ice too tightly. Ensure space for gas to expand and escape.

  5. Seal the Cooler Loosely:
    Don’t completely tape the cooler shut. A slight gap will allow the CO₂ gas to escape safely.

  6. Label Your Cooler:
    Clearly mark the cooler with a label indicating that it contains dry ice, including the net weight in kilograms (UN1845).

Quick Checklist for Packing Dry Ice:

  • Prefreeze items before packing.

  • Choose a vented cooler with space for gas expansion.

  • Place dry ice on top of the items.

  • Leave room for gas to escape.

  • Ensure clear labels and markings (UN1845).


2025 Peraturan: What You Need to Know About Using Dry Ice for Shipping

Direct Answer:
Di dalam 2025, regulations for shipping dry ice are primarily governed by IATA’s PI954 and FAA guidelines. When shipping or transporting dry ice, you need to follow specific rules about packaging, pelabelan, dan ventilasi.

Key Regulations:

  • Ini PI954:
