The larger the packaging, the lower the test pressure.
We recommend 2 possible methods to determine the pressure to be applied:
1st method: Begin the tests under low pressure, do not strain the packaging and observe the effect of the process on the overall quality of the packaging.
2nd method (faster and effective in 90% of cases): Carry out 1 or 2 burst tests, then divide the pressure obtained by 5 and apply the result as the stress pressure for leakage. Regardless of the level of pressure applied, sensitivity will not be reduced but the pressure will enable faster testing.
