Humidity Indicator Plugs

  Description

Humidity indicator cards are ideal for ensuring that your moisture barrier bags and desiccants have successfully carried out their job. Moisture sensitive spots on the cards respond to various levels of humidity with a very noticeable color alteration from blue to pink. The humidity indicator card will indicate the humidity level of whatever you are packaging when the card is checked after the bag is first opened. If your application involves a flexible barrier bag, then a humidity indicator plug would most than likely work best for you.
