Abstract — Manufacturers of multi-layer films can realize significant cost savings, product quality improvements, and reduce the risk of product failures by accurately measuring individual layer thicknesses of multi-layer materials instead of relying on gauging that can only provide total thickness. Lumetrics’ OptiGauge II can measure the individual layer thickness of multi-layer medical, industrial and food packaging films to submicron accuracy and can be used both online during full speed production, as well as offline QA systems.
