In applications that use barrier films, such as food and medical packaging, the standard practice is to overengineer packaging to guarantee packaging integrity. This is typically done by applying 20% or more material to the end product. However, at a high cost per pound, this could cost manufacturing operations well over six figures—annually.
Lumetrics’ OptiGauge II, a low-coherence interferometer, addresses this high-cost manufacturing issue with its capabilities in highly accurate multi-layer thickness measurements of transparent and translucent materials.
The OptiGauge helps manufacturers by:
- monitoring thickness
- providing real-time data to help control process
- reducing expensive material waste
- guaranteeing product performance
In this paper, we discuss how the OptiGauge II is ideally suited for offline or online inspection of barrier films.
