Regarding to heating efficiency, sealing processes are beneficial that generate the process heat as close as possible to the joining zone. In addition to the established ultrasonic sealing process, induction sealing is also used for aluminum-coated films. However, for material recycling, these aluminum composite films are problematic. In order to comply with the mandatory regulations of the Packaging Laws, a drastic reduction of the aluminum content in the composite is one option. Due to metallization of a plastic carrier film, the mass proportion of aluminum can be reduced to well below 5% of the main material and can so be used in mono-material systems in accordance with the legal bases. While metallized films have already been widely investigated and applied regarding to their barrier effect and protective function, no systematic investigations are known for induction sealing. This gap is to be closed by the project in approach and a first data basis for the potential of induction sealing is to be shown.
