ActivePlastics—Film and sheeting—Determination of gas-transmission rate—Part 2:Equal-pressure methods
塑料制品 薄膜和薄片 气体透过性试验方法 第2部分：等压法
Application Summary AI generated
This standard specifies the equal-pressure method for determining the gas transmission rate of plastic films and sheets. It is primarily applied in quality control and material selection for packaging industries, particularly for evaluating the barrier properties of flexible packaging materials used in food, pharmaceutical, and electronic product preservation. The method is suitable for testing oxygen, carbon dioxide, and other non-corrosive gases under controlled temperature and humidity conditions.
