The Analysis of Relationships between Surface Porosity and Air Permeability of Paper (board)

Abstract:

Scanning Electron Microscope (SEM) was used to scan the surfaces of 9 kinds of food packaging paper, and the surface porosity of them was analyzed according to fractaltheory. To study the relationships between surface porosity and the air permeability of the paper samples, Schopper air permeability tester was used to test the air permeability of the samples. By fitting experimental curve, the relationships between the surface porosity and air permeability were obtained. It demonstrated that the fitting curve described the profile of the experimental values very well and the air permeability depends exponentially on surface porosity over a large range of porosity and the fitting curve equation is Ps=1.132e^15.89A.
