Dehydrating support for packaging of e.g. granular product, has indicator indicating saturation point on one of sides of support, and transparent protection unit protecting saturation indicator and forming barrier to humidity
Dehydrating support comprises an indicator (2) indicating saturation point on one side of the support. A transparent protection unit protects the saturation point indicator and forms a barrier to the humidity. The support is formed by a dehydrating material. The indicator is deposited on the support and contacts the support by utilizing a substrate permeable to the water vapor and receiving the indicator. An independent claim is also included for utilization of a dehydrating support for packaging of products sensible to the humidity.
