The SCS 6HIC200 Humidity Card Indicators are printed with moisture sensitive spots which respond to various levels of humidity with a visible color change from blue to pink. The humidity inside dry packed barrier bags can be monitored by including an HIC inside. When the bag is opened, the card can be examined for proper dryness inside the bag. This indicates that the barrier bag and desiccant functioned correctly. The SCS (3M) 6HIC200 Humidity Card Indicators are used in a variety of dry packaging applications.
