Humidity Indicator Cards (HIC’s) are used to determine when products have been exposed to moisture above recommended storage levels.

They are printed with moisture sensitive spots, which respond to various levels of humidity with a visible colour change from blue to pink.

The humidity inside dry packed barrier bags can be monitored by including a 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 the desiccants are functioned correctly.
