Humidity Indicator Cards play a major roll in completing the Moisture Barrier Packaging assembly. They are there to provide a simple, reliable, visual indication of the relative humidity within a sealed package or any given environment. HIC’s are small chemically impregnated paper instruments designed to monitor relative humidity levels. Per the below attachment (Humidity Indicator Cards Available Configurations) they can range from as low as 5% and as high as 95% depending on the application and need. Humidity Indicator Cards help provide visual proof of the relative humidity level and help indicate and alert the end user to know when they need to replace their desiccant bags and check product for possible damage.
