What is Container Rain
and Blue HighlightWhy Does It Matter?

Each year 10% of products delivered around the world are damaged by repair by humidity and temperature changes creating what we call “container rain” - which causes mold, corrosion, peeling and destroyed packaging.

Throughout every voyage, temperature fluctuations will cause humidity as the air inside a shipping container cools. And it’s not just the air inside your shipping container that may contain moisture - cargo with a high fibrous construction, such as clothes, furniture and agricultural products, and many types of packaging material may also contain moisture which is released when the air cools.

Container rain is a complex mechanism, which depends upon many factors, including transit route, time of year and cargo packaging (cardboard and wood can absorb moisture and regulate atmospheric humidity).

There are three distinct phases to RH in container shipping.

Container rain is Blue Highlightmore likely to occur in phase one and three, as this is where the largest changes in RH and consequently, the formation of condensation occur.

BirchSorb Product

Container rain can be disastrous for a consignment, resulting in shipments being destroyed by moisture and fungus and replacement journeys being made. However, White Highlightthere is a solution.

Our unique formulation absorbs humidity from inside the container or packages and locks it away chemically in a solid matrix. Empirical evidence shows the blend of multiple active ingredients plus sophisticated packaging ensures exceptional moisture control in all three phases of the journey:-

Phase 1

Phase 1

Fast-acting components absorb moisture and begin to set in a solid matrix.

Phase 2

Phase 2

Moisture is chemically bound in an exchange between fast and slow-acting components and won’t release moisture back into the atmosphere.

Phase 3

Phase 3

Further moisture absorption capacity is realised as a result of the slow acting components and gives BirchSorb its extended life.

Moisture control and desiccant solutions prevent the build-up of moisture in the air, effectively eliminating container rain at the source. However, while traditional moisture control products are often only effective for very short periods of time, BirchSorb features an innovative blend of chemicals designed specifically for long routes - making it powerful and long-lasting.
