Wall thickness measurement of blown film production

Film thickness measurement in the plastics industry

Our dedicated interferometric sensors of the CHRocodile 2 IT series and the CHRocodile 2 K measure the thickness and topography of various types of plastic films, containers and PET bottles. Such application flexibility is convenient, especially during film production, as different machine parameters can be instantly adjusted based on the sensor’s values. The infrared light source of the interferometric sensors enables the thickness of different kinds of even optically non-transparent or completely opaque plastics to be measured. What’s more, thin film is measured with the same precision as any thicker plastic material.
