Detecting and measuring reduction in barrier performance of multilayer films requires advanced measurement tools and techniques. This paper will describe how to detect gauge variation of barrier layers within multilayer film structures during the extrusion process. The second half of the paper will review root causes and options to minimize gauge variation of barrier layers.
