Researchers at the Fraunhofer Institute in Germany have created humidity regulating films incorporating salts that absorb water vapour leading to extended shelf life and better product appeal.
Sven Saengerlaub and Karin Agulla found the sorption quality of calcium chloride and sodium chloride to be much higher than that of polar polymers such as polyamide, cellulose fibers and desiccants, such as silica gel.
The researchers said the novel polymer composite films stabilize the relative humidity
