Gas Barrier Performance Testing of Plastic Films How can we ensure plastic films effectively block air? Why is it necessary to test this property? First, whether packaging materials can effectively block air directly impacts product quality, preventing spoilage and oxidation while ensuring product integrity. To determine a material's barrier properties, specialized testing equipment is required. Saicheng's differential high-precision sensors, accurately assesses material performance and provides reliable data support.

G103H Gas Permeability Tester Single-chamber and multi-chamber designs accommodate diverse testing requirements. Testing Principle The instrument employs a differential pressure testing principle. The pre-treated sample is placed between the upper and lower test chambers and clamped securely. First, the low-pressure chamber (lower chamber) is evacuated, followed by evacuation of the entire system. Upon reaching the specified vacuum level, the lower test chamber is sealed. Test gas is then introduced into the high-pressure chamber (upper chamber) at a predetermined pressure, ensuring a constant...

(adjustable) pressure differential across the sample. Under the influence of this pressure gradient, gas permeates from the high-pressure side to the low-pressure side. By monitoring the pressure increase in the low-pressure chamber, the barrier properties of the tested sample are determined. • Intelligent operating interface with touchscreen design • Simultaneously measures gas transmission rate, gas transmission coefficient, solubility coefficient, and diffusion coefficient of test specimens • Wide-range, high-precision temperature control accommodates testing under various experimental conditions...
