Container Humidity Control
Guide to keep your products dry: moisture control in containers
What is the result or damage from moisture?
Metals corrode, discolor and lose their shine
Cargo and packaging get moldy, soft, crumbled and discolored.
Bad odor
Physical damage from water, ice, caking etc
Moisture Damage can be Prevented
All containers contain moisture from the time of loading. No container is completely airtight. Moisture will move in and out of the container during the course of the voyage known as “Container Breathing”. The objective of a moisture protection program is to prevent the buildup of moisture in the air to levels where it may cause damage. This is done by reducing the amount of the moisture entering the container and by using desiccants to remove moisture from the air.
The key is to place enough desiccants (at least 4 kg per 20′ container for those outside the cartons, from what I heard), but also to select desiccants that work for long enough. Once they are full of water and can’t absorb anything anymore, they start releasing water back into the air!
Cargo sweat: This occurs when moving cargo from a cold or temperate climate to a tropical one. The air containing moisture or water vapour condenses-out on the cargo or its packing.
Container sweat: This is water vapour in the air condensing or forming on the inside surfaces of the container when moving from tropical or temperate climates to cooler areas.
Fungi, moulds and mildew do not usually cause any problems below approximately 55% Relative Humidity.
The effect or onset of corrosion is a function of many variables where humidity and time are also present.

During transit of cargo, as the temperature inside the container will rise and fall betwwen day and night, the relative humidity inside the container also fluctuate, leading to container rain and cargo sweat.
