What are Humidity Indicator Cards?
The presence of moisture/humidity can prove to be very harmful for
products. If the packages contain very
high levels of dpacke humidity it will react negatively with the packed goods. Humidity can ruin the products
and bring about various physical as well as chemical changes in them. It is in
order to prevent such happenings that companies make use of different objects,
which give indications about the humidity levels in packages. Once these
indicators are in place, one can easily control the moisture content present in
closed spaces. Some of the commonly used moisture indicators are Silica Gel,
Activated Alumina and Humidity Indicating Cards.
Functioning of Humidity Indicating Cards Explained
The Humidity Indicating Cards work in a very simple manner. They are not actual absorbers of moisture, just indicators of whether the humidity is at the optimum levels. When the Humidity Indicating Cards show that higher moisture levels are reached, it is an indication that the adsorbents present in the closed spaces are saturated and need to be replaced.
When the Humidity Indicating Cards come in contact with the moisture, they will respond as per their various sensitive spots. Different moisture levels will affect different moisture spots and each will react in a different manner to show various moisture levels. The
changes can be in various shades-
blue to pink colour and vice versa, green, orange and white. The white usually indicates that all
the moisture colour has been removed from the packages. It clearly shows that the
molecular absorbents placed inside have reached their saturation point and need
to be replaced as soon as possible. This is the biggest advantage of using
Humidity Indicating Cards.
