Introducing the GB-M2 Leaking/Sealing Tester from Hylec Controls – a cutting-edge solution leveraging compressed air and a high-precision electronic pressure sensor for evaluating the sealing process and performance of flexible packages. With microcomputer control, this advanced tester not only compares and assesses sealing effectiveness but also provides critical scientific information to determine relevant technical requirements. Tailored for the sealing performance test of flexible packages, it finds applications in the food, pharmaceutical, daily chemical, and various other industries.

Test Principle Evacuating the vacuum chamber induces a pressure difference between the inside and outside, enabling observation of gas escape or water infiltration in the water-immersed sample, facilitating accurate judgment of the sample's sealing performance.

Standard Compliant with ASTM D3078.
