Humidity Indicator Cards



These Humidity Indicator Cards (HICs) give you an easy means of identifying humidity conditions inside a moisture barrier bag after vacuum packaging. The indicator spots on the HICs change from blue to pink as humidity increases and from pink to blue as humidity decreases. Spots indicate 5, 10 and 60% humidity
