Inline tightness

Leaky packages can have severe consequences such as complaints, pose a threat to its image, loss of customers or increasing costs. It is, consequently, important to measure the tightness of food packages.

Results of the AiF-project ‘Tightness of pouches’ suggest test gas based methods to be used to determine tightness of packages.

The aim of the project ‘Inline tightness’ is to test whether leakages and quality defects in food packages can be detected and measured with test gas based methods. Subject of the considerations are MAP packages (Modified Atmosphere Packaging).

Within the project the following results shall be established:

• identification of test gas based methods to determine the tightness of packages which are available on the market
• determination of limits of these methods for special MAP packages
• compiling a data sheet which displays the suitability of the analysed methods for special MAP applications
• compiling a specification sheet to integrate a inline test method into the process

With the help of inline tests methods quality problems can be detected as fast as possible. As a result the production of faulty products can be minimised.
