What is Moisture in Shipping Containers?
Moisture and humidity pose significant risks to goods stored and shipped in containers. Moisture can cause a range of damages, including:
- Rust and corrosion of metal components
- Mold and mildew growth on organic materials
- Deterioration of packaging materials
- Damage to sensitive electronic equipment
Consequences and Prevention of Moisture in Shipping Containers
Moisture can infiltrate shipping containers during various stages of transportation, including:
Load Location: Moisture can be present in the original location of goods, such as humid environments or areas prone to flooding.
Transportation: Containers may encounter moisture and humidity during transit, particularly when crossing bodies of water or traveling through humid climates.
Unloading: Moisture can accumulate during unloading, especially if done in humid or rainy conditions.
To prevent moisture damage, several measures can be implemented:
Moisture Testing: Conducting moisture tests on shipping containers before loading helps to assess the extent of humidity and moisture present, enabling the implementation of appropriate protective measures.
Desiccants: Desiccants are moisture-absorbing substances that can be placed inside containers to reduce humidity and prevent condensation.
Vapor Barriers: Vapor barriers, such as polyethylene liners, can be placed inside containers to prevent moisture from entering.
Ventilation: Proper ventilation allows air to circulate and reduce moisture buildup. Containers should be equipped with vents or openings.
Container Monitoring: Sensors can be installed inside containers to monitor humidity and moisture levels, allowing for timely intervention if necessary.
Conclusion
Moisture control is crucial for safeguarding goods shipped in containers. By understanding the sources of moisture, employing preventive measures, and conducting moisture tests, businesses can effectively minimize the risks of moisture damage, ensuring the safe and secure transportation of their products.
