Thin layers – high functionality

By Willi Lindemann, R&D Engineer – Inline Coating Technology, Brückner Maschinenbau GmbH & Co. KG

Many plastics film properties are directly related to the surface characteristics and chemical constitution of the outer layer. Especially for polyolefin-based materials, a further converting step is not purposeful without suitable surface treatment, e.g. corona, flame or plasma. By using one of these conventional technologies, it is possible to increase the surface tension – but the treatment level is limited and only temporary.
