摘要：
Hydrophilic, regenerated cellulose films are characterized by certain adsorption properties. These investigations were aimed at determining to what extent the moisture content of a film might decide its barrier capacity against wafer vapour. The experimental materials were an unlacquered regenerated cellulose film and one varnished on both the sides with nitrocellulose lacquer. The investigations allowed us to propose some models that formally describe the adsorption process of water vapour through films at different values of ambient relative humidity. In addition, we determined the functional relation between the water vapour permeability of the films under investigation and their moisture contents and equilibrium ambient relative humidity values.
