of Reference Material
125μm polyester film gas permeability reference material
This reference material is polyester (PET) film, whose thickness is 125μm. It can be applied to food, drug and electromechanical industries and so on. It is used to calibrate the gas permeability analyzers, which adopt Pressure Differential Method, of packaging materials’ gas barrier property; and to evaluate the testing process of such gas permeability analysis.
Sample preparation
This reference material is made of 125μm roll polyester (PET) film. After processes of cutting, filtrating and numbering, it is well packed in lightproof sealed package.
