Shipping Container Transport: Prevent Condensation and Heat Damage
Sea Container Transport: Prevent Condensation and Heat Damage
Shipping temperature-sensitive goods via sea container presents challenges. A regular dry container can reach temperatures of 50°C+ in tropical areas. Additionally, condensation (container rain) can occur, damaging the cargo.
What is Container Rain?
Container rain occurs due to temperature fluctuations during transport. Warm, humid air inside the container cools down at night. The condensation forms on the ceiling and falls onto the cargo like 'rain'. Cardboard becomes soggy, metal products rust, and electronics get damaged.
Solutions for Sea Container Transport
1. Container Liners (Thermal Inner Liner)
A thermal container liner is a complete insulating inner liner for 20ft, 40ft, or 45ft containers. Advantages:
- Keeps temperature stable (both heat and cold outside)
- Protects against condensation
- Easy to install during loading
- Disposable or reusable
2. Container Dry Bags (Desiccant)
Dry bags actively absorb moisture from the container air. A typical 40ft container requires 8-12 dry bags for effective moisture control over 30+ days.
3. Combination
For maximum protection: combine a thermal liner with dry bags. This is recommended for:
- Pharmaceutical shipments
- Temperature-sensitive chemicals
- High-value electronics
- Food products for long transports
- Flower exports to Asian markets
When to Use Which Solution?
| Risk | Recommended Solution |
|---|---|
| Moisture control only | Dry bags |
| Temperature fluctuation only | Container liner |
| Both risks | Combination of liner + dry bags |
| Strict GDP/pharma | Reefer container + container liner as backup |
