Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Film Gas Permeability Testing Methods Comparison Film permeability testing plays a crucial role in material and quality control for flexible packaging. This report focuses on two main test methods for auto gas permeability: differential pressure and equal pressure. Differential Pressure Method The differential pressure method is the established standard for scientific research due to its versatility and ability to test various gases. It operates by creating a pressure difference across the film sample. Two sub-methods exist within this category: Vacuum Process: This method utilizes a 0.1MPa pressure difference to measure gas transmission rate. High-precision vacuum gauges ensure accurate and repeatable measurements. Volume Method: This simpler and cheaper alternative eliminates the need for a vacuum state, making instrument manufacturing less complex.

Comparison and Conclusion The differential pressure method offers advantages in versatility, accuracy, and the ability to test various gases. However, the equal pressure method provides a simpler and potentially more cost-effective solution for specific oxygen permeability testing. Both methods have their limitations, and the choice depends on the specific testing...
