3M Humidity Indicator Cards are printed with moisture sensitive spots which respond to various levels of humidity with a visible color change. HICs are used inside vacuum sealed moisture barrier bags to monitor the interior humidity conditions.
When a bag is opened, the card can be examined to verify proper dryness inside the bag. This indicates that the moisture barrier bag and desiccant functioned correctly. Click on Documents tab for additional sales and technical literature.
