Humidity Indicator Card (HIC) is a convenient, low cost and safe method to check the environment humidity. We can judge the humidity inside the packing from the color changed. If humidity of packaging equal or over than that humidity value, the dot on the card will be changed color from DRY color to WET color, so that it is easy to know the desiccant' s application effect.

Since 2004, the regulations of environmental protection in European Union(2004/73/EC) has listed cobalt  chloride as second-class cancerogenic substance, now the humidity indicator card contains cobalt is forbidden using substance, all products exported to European Union countries must conform to that regulations. Therefore, the (blue to red) humidity indicator card which major constituent is cobalt chloride, is forbidden using.

In order to meet the relevant laws and regulations, TOPCOD humidity indicator card department produces a new generation environmentally friendly humidity indicator card. With fully automated machines production, our daily capacity over 1,000,000pcs.
