Gas Transmission Rate Testing For Packaging Material

  Product Introduction     The GB-ML Leakage Tester is a professional testing instrument powered by compressed air, which controls the lifting and lowering of the sealing barrel lid through an air cylinder.   Adopting a high-precision electronic pressure sensor and a microcomputer control system, it effectively compares and evaluates the sealing process and sealing performance of flexible packages, and provides a scientific basis for determining relevant technical requirements.   This equipment is suitable for sealing performance testing of flexible packages in food, pharmaceutical, daily chemical and other industries.   Testing Principle   The sample is immersed in water, and a vacuum is applied to the vacuum chamber to create a pressure difference between the inside and outside of the sample.   The sealing performance is judged by observing gas escaping from the sample or water penetrating into the sample.     Applicable Standards   GB/T 15171, ASTM D3078-2002 (2013), USP 1207.2 Item Technical Parameters Vacuum Degree 0～-90 kPa Vacuum Accuracy ±1% of indicated value Vacuum Holding Time 0.01 s～99.99 h Sealing Barrel Size Standard: Φ600×591 mm; other sizes optional or customizable Effective Vacuum Chamber Size Standard: Φ550×396 mm; other sizes customizable Air Inlet Pressure 0.6～0.8 MPa Power 50 W Instrument Dimensions 1005×802×1307 mm Power Supply 220 V, 50 Hz   Product Features   High-quality components, stable and reliable   Built-in high-precision pressure sensor with high sensitivity, enabling real-time monitoring of inlet pressure.   Full-automatic operation system   Vacuum degree and holding time can be set as required. The instrument automatically completes vacuuming, holding, stopping and air-releasing.   Brand-new pneumatic system with fast inflation and return, achieving balanced pressure inside and outside.   Key-controlled cylinder for automatic opening and closing of the sealing barrel lid, labor-saving and convenient.   Supports multiple test methods   Supports bubble method and dye penetration method for leakage / integrity testing.     Application Areas   Plastic Packaging   Leakage testing for plastic bags, plastic containers (bottles, cans, boxes), etc.   Glass Packaging   Leakage testing for food bottles, pharmaceutical glass containers, daily chemical glass bottles, etc.   Metal Packaging   Leakage testing for cans, easy-open cans, aerosol cans, metal hoses, etc.   Other Applications

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.
