Apa Yang Terjadi Jika Kantong Es Kering Menjadi Basah? Keamanan & Perbaikan
Ketika sebuah dry ice bag gets wet, sublimation surges, CO₂ gas builds faster, and hold time drops. If a dry ice bag gets wet inside a sealed shipper, pressure can rise and create safety risks. You need fast, simple steps that stabilize temperature, menjaga kepatuhan, and keep people safe. One kilogram of dry ice produces ~541 L of CO₂ gas, so ventilation is non-negotiable.

Why does a dry ice bag get wet—and what happens next?
Jawaban singkat: Water is a heat highway — when a dry ice bag gets wet, sublimation accelerates.
Condensation forms as warm, humid air meets a cold surface. If liquid water touches dry ice, heat transfer increases dramatically and CO₂ release spikes. Expect faster fogging, durasi pendinginan lebih pendek, and higher internal pressure if vents are blocked.
Moisture on the film or in the cavity turns into a heat bridge. You’ll see sweating, frost crusting, and labels loosening. In sealed liners, pressure rises as CO₂ accumulates. Di ruang terbatas, that gas can displace oxygen — always keep the area ventilated.
How much CO₂ is released when a dry ice bag gets wet?
A dry ice bag that gets wet releases CO₂ much faster.
1 lb of dry ice generates about 250 L of CO₂; 1 kg generates ~541 L. That can deform packaging or pop seams if a liner is sealed. Use vent-able folds or micro-perforations; never knot or heat-seal a liner.
| Exposure scenario | Estimated rate | Risk level | Impact on shipment |
|---|---|---|---|
| Kering, well-vented | Lambat | Rendah | Predictable hold time |
| Humid air | Sedang | Sedang | Slightly shorter cooling duration |
| Direct water contact | Tercepat | Tinggi | Pressure build-up and temperature loss |
Practical tips when a dry ice bag gets wet
-
Jika di dalam ruangan: Move to a ventilated area; open liner folds; wipe moisture; replace soggy inserts.
-
Selama memuat: Add a vapor barrier around the payload and ensure the ice compartment can vent.
-
If frequent: Add splash shields or use higher-grade insulation designed for humid lanes.
Contoh kasus: A pharmaceutical lab found that replacing unlined bags with moisture-resistant composite liners extended temperature hold time by 24 hours on 72-hour routes.
What should you do if a dry ice bag gets wet in transit?
Act fast: ventilasi, verify vent paths, remove water, replace wet components, and document for compliance.
Your goal is to restore thermal performance and maintain safety.
-
Beri ventilasi pada area tersebut — CO₂ is heavier than air.
-
Check venting — never seal dry ice in an airtight liner.
-
Remove free water — wipe surfaces dry.
-
Replace insulation — wet fibers conduct heat rapidly.
-
Re-label — use freezer-grade materials.
-
Record details — time, lokasi, dan tindakan korektif.
| Melangkah | Alasan | Time needed | Keuntungan |
|---|---|---|---|
| Ventilasi | Prevents gas buildup | 1–2 min | Keamanan pertama |
| Verifikasi ventilasi | Avoids liner rupture | 1 menit | Kepatuhan |
| Remove moisture | Reduces heat transfer | 3 menit | Longer cooling |
| Replace inserts | Restores insulation | 5 menit | Stable temperature |
How to prevent a “dry ice bag gets wet” scenario
Control humidity, pre-condition packaging, and design for venting.
Maintain packing rooms below 40% RH, pengirim pra-dinginkan, and use hydrophobic liners. Avoid over-packing — leave vent space above the refrigerant.
| Prevention Tip | Metode | Hasil |
|---|---|---|
| Kontrol kelembaban | Dehumidify pack-out rooms | Less condensation |
| Pre-conditioning | Cool boxes before loading | Reduces dew formation |
| Liner upgrade | Use hydrophobic multi-layer film | Stops direct moisture |
| Proper venting | Melipat, jangan disegel, liner tops | Prevents over-pressure |
2025 developments and trends that matter
New packaging technologies make it easier to prevent moisture damage. Smart CO₂ and humidity sensors can detect when a dry ice bag gets wet before it compromises hold time. VIP shippers and closed-loop containers extend cold retention and minimize waste.

-
Sistem yang dapat digunakan kembali – lower waste and maintain consistent performance
Wawasan pasar: Global adoption of smart and sustainable cold-chain solutions is increasing as compliance and efficiency pressures grow.
FAQ
Is it dangerous if a dry ice bag gets wet?
Ya. Faster CO₂ release can displace oxygen and create pressure. Jaga agar paket tetap berventilasi.
Why does fog appear when a dry ice bag gets wet?
Heat from water drives rapid sublimation, and the gas condenses moisture in the air.
Can I reuse a liner after it gets wet and freezes?
Only if it hasn’t cracked and still vents safely.
Should I seal a wet liner to keep water out?
TIDAK. Leave venting open — seal moisture out at the payload level instead.
How much gas is produced?
Tentang 250 L per pound, atau 541 L per kilogram of dry ice.
Ringkasan dan Rekomendasi
When a dry ice bag gets wet, sublimation speeds up, CO₂ rises, and insulation efficiency drops.
Vent immediately, verify vent paths, remove moisture, and replace damaged parts.
Prevent recurrence through humidity control, better liner materials, dan pelatihan.
Langkah selanjutnya:
Audit your SOPs, upgrade to moisture-resistant liners, and test CO₂ sensors on humid routes.
