Permeability - Breathability - Porosity

Online Air Permeability Analyzer

Most on-line instruments measure and control only one film property. In addition to final film porosity, which is an important property for some film grades, ACA Permi is a universal analyzer of film quality for most film grades due to the fact that almost all process parameters have a clear effect on porosity.

On the other hand, porosity correlates with almost all physical film properties. If porosity is constant, film process performs well and film quality is consistent.

With a fast ACA Permi porosity analyzer it is possible to improve the process so that basis weight and moisture controls work better and the fast peak-to-peak variation, which cannot be seen in the scanner measurement, is lower and thus runnability is better.
