Abstract
Sorption isotherms of different papers and cellophane were determined with different sorption devices in the temperature range of 10 to 30 °C. It was found that the three-parameter Guggenheim-Andersen-de Boer (GAB) equation fits the isotherms of paper with great accuracy.
In addition an experimental method is described, by which the water content of packaging material can be simply and accurately measured, using the principle of pulsed NMR. The simplicity of the pulsed NMR method makes it eminently suitable for purposes such as production monitoring and production control. The main advantage compared to classical methods is the speed of measurement: the total measurement time is only a few minutes.
