Shipping containers are built strong to withstand the elements and protect the cargo within as they travel thousands of miles across the sea.
But there is one culprit that can sneak inside and damage goods, causing millions of dollars worth of losses.
Humidity and moisture. When the walls of the container become cooler than the air outside, moisture builds on the walls and roof, dripping onto packaged goods and damaging the container’s interior.
If left unchecked, mold, corrosion, and warping are some of the consequences that can have detrimental financial effects on your supply chain.
Fortunately, there are a few ways you can prevent humidity and moisture from wreaking havoc on your shipping containers. We share our best tips in this post!
Generally, pallets are made of wood, but wood holds moisture. That’s why it’s good practice to check the moisture content in different pallets before using them.
The fresh wood used in newer pallets often holds more water than older pallets that have been stored in a dry place. This moisture is given off into the air inside of a container, increasing the condensation level. The same goes for older pallets that have been kept in a cold, wet environment.
Plastic pallets are the best choice to combat humidity since this material doesn’t retain moisture. If you do use wooden pallets, inquire about whether they were dried before use.
One way to prevent moisture from wreaking havoc on your container is to ensure its properly outfitted for ventilation and insulation.
Insulation keeps your cargo warm, preventing the temperature fluctuations that cause condensation to form.
Ventilation allows air to flow in and out, balancing the inside and outside temperatures. Warm, moist air is pushed outside, while fresh air is drawn inside the container. This equalized climate reduces moisture considerably.
A final way to safeguard against humidity inside your container is to utilize desiccants. These are products that contain special ingredients to absorb moisture from the air.
Desiccants can be found in many forms, including bags, blankets, and pads.
Place the desiccants inside the container at strategic locations to suck up condensation and protect your products and packaging.
