Protect Goods Using Shipping Container Desiccants

What is Container Rain?

Container Rain is a common problem faced by companies while transporting goods in shipping containers across long distances. This phenomenon is named “container rain” because of the condensation of moisture like rain in the shipping containers. This phenomenon is harmful for the products as the exposure to excess moisture can damage the packed goods and make them unusable. If issues like container rain are not solved then it will result in heavy losses for the companies transporting goods. Not only will their products be destroyed, they will have to suffer heavy financial losses as well.  

So how does container rain occur? This phenomenon takes place when there is a change in temperatures. As the shipping containers carrying the packed products travel through different climate zones, there will be a sudden change in temperature and weather conditions. The shipping containers will move from warm and humid conditions to cooler conditions and this sudden change in temperatures will result in condensation of moisture inside the containers. This will lead to cargo damage and as a result, financial losses also.

 How Container Rain Takes Place?

The phenomenon of container rain is explained as follows- When the shipping containers move from warm climate to cooler areas, then the warm, humid air in the containers condenses and “container rain” takes place. The condensation occurs all over the place - the cargo, inner ceiling and the container walls. The condensation of moisture will take place on the coolest surface available and will be so much that it will be literally “raining” inside the container. The “container rain” phenomenon will take place every 24 hours till the relative humidity levels are reduced.

Importance of Shipping Container Desiccants

In order to safeguard packed products being transported in shipping containers, companies make use of shipping container desiccants, which will absorb all the extra moisture present in the containers. Shipping container desiccants are desiccants/absorbents, which will absorb all the excess moisture in the most effective manner possible. When placed alongside the packed products, the container desiccants will trap the moisture molecules in such a way that they will not be allowed to move out and the shipping containers will remain “moisture-free” till they reach their final destination.

The use of shipping container desiccants is very important in the shipping industry as it will ensure that moisture molecules will not condense in the containers and destroy the packed products.
