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 color from blue to pink as humidity increases and from pink to blue as humidity decreases. Our HICs:
Offer superior protection, especially when used with our Desiccants and Moisture Barrier Bags
