To offer the electronics and semiconductor industries an environmentally friendly Cobalt Free Humidity Indicator (HI) card.
What are they?
Cobalt Free HI Cards provide humidity level indication for dry packaging to electronic and semiconductor manufacturers who desire a card without cobalt.
Why use them?
Many products are highly sensitive to moisture. In order to constantly verify that dry packaging methods are not compromised during storage and transport of these products, humidity indicator cards allow users along the supply chain to monitor the package conditions. Indicator spots change from brown to green after exposure to the relevant relative humidity conditions. The cards are reversible and change as conditions change in the packaging environment, allowing users to monitor the conditions of product packaging. The environmentally friendly Cobalt Free HI cards do not contain cobalt and some configurations can be produced with less than 900 ppm halogen levels where required.
