What is Container Rain and Why Does It Matter?

Approximately 10% of all goods transported in shipping containers are damaged by container rain every year, causing discarded goods, replacement fees and expenses, and higher insurance premiums. Container rain is bad news for both logistics companies and manufacturers – but what is it, and how can it be prevented?

When goods are transported, containers are subjected to humidity changes and temperature cooling as the route transports the goods from one climate to another. These humidity changes create condensation within the container, leading to mould, mildew, corrosion and damp which damages the goods inside. 

While using appropriate packaging material can reduce moisture within the container, long journeys are still vulnerable to the issue.

Moisture control desiccants prevent the build-up of moisture in the air, stopping container rain at the source. But traditional moisture control products are often not sufficient for long shipping routes, unable to last for the duration of the entire journey.

When we developed BirchSorb®, we wanted to create a hyperdesiccant™ capable of lasting for the entire shipping route, providing complete moisture control for the entire journey. BirchSorb® is able to last for up to 12 weeks, with a controlled absorption rate that means it prevents the build-up of moisture – and the resulting container rain – throughout.
