塑料薄膜和薄片气体透过性试验方法 压差法
Application Summary AI generated
This standard specifies a differential-pressure method for determining the gas transmission rate of plastic films and sheets. It is primarily applied in the packaging industry to test the barrier properties of materials used for food, pharmaceutical, and electronic product packaging. The method is also used in quality control and material development to evaluate how well a plastic film resists the permeation of gases like oxygen, nitrogen, or carbon dioxide.
