SUPERDRYPAK™ Humidity Indicator Cards show users when the Relative Humidity has risen above a certain level within a sealed package. These cards are widely used in the packaging industry, as they offer assurance that goods have arrived in working order. Given that there isn’t one humidity level above which products are damaged, we offer a ‘1-spot’ HIC that turns from blue-to-pink at 8% RH, and a ‘6-spot’ card; that features indicators for 10%, 20%, 30%, 40%, 50% and 60% RH combined.
