WATER VAPOUR PERMEABILITY CUP
Overview of WATER VAPOUR PERMEABILITY CUP
This tester is used to evaluate the permeability of plastic film and moisture-proof packaging material for processed paper and coating according to the cup method.
The permeability obtained by this method will be the mass of vapour that went through the unit area of membranal material during a specific amount of time and prescript temperature and humidity conditions.
