What is container rain?

When container ships travel around the world, they pass through a range of temperatures. When a container ship moves from a hot, humid environment (like Malaysia) to a cold, dry environment (like Canada), moisture releases from the air and condense as water droplets over the course of the journey — just like it condenses on your window pane at home on a cold day.   

Container rain is a top driver of losses in the shipping industry. Approximately 10% of cargo is discarded annually due to moisture damage.  

Flow Dry’s container bags are designed to absorb moisture as it releases into the air – so that your products do not.
