Humidity indicator cards (HICs) provide a low-cost method of indicating humidity conditions inside a moisture barrier bag after vacuum packaging.
The indicator spots on the HICs change colour from blue to pink as humidity increases and from pink to blue as humidity decreases. The early identification prevents damaged items from entering production by identifying and/or monitoring humidity levels prior to opening inner contents.
Cobalt-dichloride free humidity indicator cards provide electronic and semiconductor manufacturers with a JEDEC-compliant humidity indicator card that is free of Cobalt-Dichloride, a chemical regulated under European Chemical Bureau (ECB) REACH directives. To offer the electronics and semiconductor industries a cobalt-dichloride (CoC12) free humidity indicator card, while maintaining the accuracy required by international JEDEC standards.
