Snacking companies are worried about the crisp of the product, which is damaged very fast in the presence of humidity, particulary if the packaging is drilled. Defects of the envelope and sealings can easily annihilate the barrier property of the film.
The breathability of the packaging is also determining, as shown by a historic French manufacturer testimonial: « For biscuits I needed to determine the level of breathability below which aromas are stacked into the package giving bad smell to consumer at opening. »
«的新产品required gas flushing, I had to change the type of film and test sealing. I was able to do the diagnosis with the Exos in 10 samples when before I would have passed 2 weeks of trials. » explains a French industrialist.

The technique used by EXOS and OXYLOS allows to control:
The reached performances are such as the sensibilities, or detection limit, can go down to 5µm equivalent diameter perforation. as a reminder a bacterium measures 1µm, a hair measures between 40-70µm.
The sensitivity of the device allows to discriminate by experiment, the causes of leak among the following examples:
Thus, the level of sensitivity makes it possible to control the integrity of the packaging which will preserve the atmosphere over time.
