Traditional desiccant bags are used inside packages of various sizes and serve to protect the product from the moisture that forms inside them. Container desiccants are obviously used inside freight containers to lower the level of humidity that is created inside them during transport, but they are also widely used inside lorries or large packages to protect products from the damage that may occur due to excessive humidity. Propadry container desiccants are available in bags and trays patented by Propagroup. The latter are also available in a Propadry chain version, designed to be hung inside freight containers.
