Whole positive pressure test of packaging bag

VIEWS:   SOURCE:http://www.at-think.com/en/  AUTHOR:aadmin
Today, the friction coefficient tester experts continue to introduce the overall positive pressure test of packaging bags.
Test principle:
The positive pressure method is more complex than the negative pressure method
Rupture test: gas is filled into the bag until it breaks, and the sealing strength is evaluated by the maximum rupture pressure;
Standard creep: fill a certain pressure gas into the packaging bag and keep it for a specific time, and judge the creep performance of the packaging bag sealing under continuous load by the change of the pressure in the package.
Creep rupture: the packing bag is filled with a certain pressure of gas and maintained for a specific time, and then the package is continuously filled with gas until it breaks. The pressure resistance performance of the packaging bag after creep is judged by the pressure change and rupture pressure in the process.
Test steps:
This step takes lssd-01 leakage and sealing strength tester as an example to introduce. The instrument adopts LCD display, and the test process is fully automatic without any manual intervention. The test process is as follows:
Place the prepared bags on the test stand
Test the needle into the packing bag sealed with rubber pad
Select test mode and set parameters
Click the "test" button, the test will be carried out automatically until the end
