Electronic Leakage Tester GB-M1 Sealing performance - negative pressure bubble method Electronic Leakage Tester for sealing performance testing of flexible packaging film Introduction The GB-M1 sealing tester uses compressed air as the power source and high-precision electronic pressure sensor as the measurement method. Through microcomputer control, it can effectively compare and evaluate the sealing process and sealing performance of flexible packages, and provide scientific information for determining relevant technical requirements. basis. It is suitable for sealing performance test of flexible packages in food, pharmaceutical, daily chemical and other industries. Test principle By evacuating the vacuum chamber, the sample immersed in water will generate a pressure difference between the inside and outside, and observe the gas escape or water infiltration in the sample, so as to judge the sealing performance of the sample. Standard ASTM D3078 Application 1.Paper-plastic composite packaging - Sealability test for paper-plastic composite bags and boxes. 2.Plastic packaging - Integral tightness test for plastic bottles, tubes, cans and boxes.
