  • Container Closure Integrity Testing is a non-destructive measurement technology based on Vacuum Decay Method and Lid Deflection performed while the package itself is held within an hermetically sealed test chamber.
  • Vacuum Decay test measures the loss of vacuum inside the testing chamber as a result of headspace gas leakage from the package.
  • A special sensor (BHS) is in place to control the integrity of the lid or foil by means of a dedicated package lid deflection algorithm. This application is suggested when applying the vacuum decay leak testing method to containers having non-rigid external surfaces. The sensor is used to detect significant changes in pack surface deflection during the execution of vacuum decay testing cycle. This technology allows to increase the detection capability and to reduce the leak testing time making it a fundamental feature, for example in the case of food trays and cups.
  • The monitoring of the vacuum level allows to identify microleaks and rejecting the faulty container.

Quality Assurance

  • Equipment test method refers to:
    • Approved industry standard “ASTM F2338-09”: “Standard Test Method for Non-Destructive Detection of Leaks in Packages”.
