Newly developed: Coating thickness analyzer


Functional thin film coatings on BOPET film enhance the film properties and the product value with improved printability and metallization, antibacterial properties, release properties, barrier properties and others.


For the evaluation of the coating quality of inline coated BOPET films it is essential to characterize the coating thickness after the stretching process at the end film, which means the measurement of the dry coating thickness as well as the coating distribution over the working width. There is a challenge to determine the organic transparent coating resin (acrylic, polyurethane, polyester) with a coating thickness of approx.


50-100 nm which is applied on an organic transparent plastic film (PET). For this purpose Brückner Maschinenbau developed an offline measurement system for automatic determination of the coating thickness deviation.
