Permeability Testing of High Barrier Films-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Permeability Testing of High Barrier Films Permeability of films is classified based on their gas transmission rate at a specific thickness. High barrier films exhibit the lowest transmission rate, followed by barrier films and low barrier films. Due to their superior gas barrier properties, high barrier films are increasingly important in the packaging industry. Since most packaging materials undergo reprocessing steps like coextrusion or lamination, it's essential to test the permeability of the final product to ensure package quality. Reprocessing can alter the physical and chemical properties of the raw materials, affecting their permeability. The chosen test method can significantly impact the results. For instance, in the differential pressure method using a vacuum, the degree of vacuum achieved in the test chamber is critical. Standards like ASTM D 1434 and ISO 2556 specify the required vacuum level. Several instrument parameters are crucial for accurate testing of high barrier films. For example, vacuum gauge and temperature control. The instrument must have a vacuum gauge with a suitable range and high precision as specified by relevant standards. The gauge's resolution, which defines the smallest detectable pressure change, is particularly important. A wider range often comes with lower resolution, requiring longer testing times for high barrier films. Temperature fluctuations can significantly affect permeability test results. The test instrument should ideally have a temperature control function or excellent insulation to minimize the impact of ambient temperature variations.
