Negative pressure packaging bag sealing instrument

Negative pressure packaging bag sealing instrumentAdopting the principle of negative pressure testing, it is suitable for sealing tests of flexible packaging in industries such as food, pharmaceuticals, daily chemical, and electronics. Through experiments, the sealing process and sealing performance of flexible packaging can be effectively compared and evaluated, providing scientific basis for determining relevant technical indicators. Sealing performance tests can also be conducted on specimens that have undergone drop and pressure tests.

Test Principle

Using compressed air as the power source, a vacuum is generated in the vacuum chamber through a vacuum generating device. Place the sample in a vacuum chamber and immerse it below the water surface; Vacuumize the vacuum tank to create an internal and external pressure difference in the sample immersed in water. By observing the expansion of the sample or the leakage of gas (bubbles) inside the sample, the sealing performance of the sample can be determined.
