Introduction: Seal tester is a use of compressed air through the vacuum source group negative pressure to detect and test the plastic packaging materials, heat sealing performance and processing technology. The instrument provides an advanced, practical and effective test method for the quality and reliability of plastic sealed packaging. The utility model has the advantages of simple operation, unique and novel appearance design of the instrument, convenient observation of the experimental results, in particular the leakage of tiny micropores in the seal Fast and effective detection. Sealing Tester The instrument is designed and manufactured in accordance with the relevant provisions of GB / T5171-1994 and GB / T 17876-1999 flexible packaging sealing performance test methods, suitable for sealing the flexible packaging in food, pharmaceutical and cosmetic industries. The test can effectively compare and evaluate the sealing process and sealing performance of the flexible package, and provide a scientific basis for determining the related technology. working principle SKZ1016A leak and seal strength tester plastic packaging seal tester By vacuuming the vacuum chamber, the test sample immersed in water is caused to have a pressure difference between inside and outside, and the gas inside the test chamber is observed to escape or penetrate inwardly to determine the sealing performance of the test sample. How it works: Differences in gas pressure inside and outside the package - Gas expansion - Gas escaping - New gas balance ... High gas ratio in the package - High gas expansion rate - Large pressure on the packaging film - Gas escape strong. Note: The parameters should be set depending on the air ratio of the product, the air ratio is high, the gas expansion rate within the package is high, the vacuum pressure should be set lower. Technical Parameters: Degree of vacuum: 0 ~ -95kPa Vacuum accuracy ± 1% (indication error) Intake pressure 0.25 ~ 0.6MPa (2.5 ~ 6kgf / cm2) Vacuum chamber size Ф270 × 490mm Measuring range -0.9 ~ 0bar The average air consumption 70L / min
