What is Gas Permeability Tester ?

Permeability of package material is one of the main factors in determining the application fields and content material quality. Since gases such as oxygen and carbon dioxide permeating through the package will exert obvious influences on product quality, a material with proper permeability should be selected while taking the guarantee period of precuts into consideration in the design of the package.
Gas permeability testing, as one of the main permeability indexes of materials, is also called gas permeation testing or gas transmission testing. It is mainly used for the permeability investigation of film and sheets for common inorganic gases. Oxygen permeability is the commonly tested object. Since the wide application of modified air packages, carbon dioxide and nitrogen permeability of package materials need to be tested as well.
