Testing Principle Gurley Method   Under a constant differential pressure of 1.23 kPa, measure the time required for 100 mL of gas to pass through the sample. Schopper Method   Select a suitable test duration under a constant differential pressure (1.00 kPa±0.01 kPa or 2.50±0.01 kPa), and calculate the gas flow rate through the sample by measuring the gas volume. Bendtsen Method   After clamping the sample for 5 seconds under a constant differential pressure of 1.47 kPa, test the gas flow rate through the surface of the sample.

Product Introduction GBB-C vertical heat seal tester can accurately measure the heat sealing temperature, heat sealing time, heat sealing pressure, and other heat sealing performance parameters of plastic packaging vertical bags, paper-plastic composite vertical bags and metal composite vertical bags(boxes). The heat sealing performance of samples of different materials are different. And the best heat sealing conditions can be accurately obtained through the determination of their heat sealing performance parameters.   Testing Principle Put the sample on the lower tray of the instrument, adjust the appropriate height according to the size of the sample, set a certain sealing temperature, time and pressure as required, and start the instrument with one key. The fixture on the instrument will heat seal the sample according to the setting parameters. Under the manual state, step on the foot switch, and the heat sealing knife is pressed. The heat sealing time is determined by the value set by the time control. In the automatic state, the upper and lower heat sealing knives of the heat sealer will automatically heat seal repeatedly according to the set time.
