Abstract
The present disclosure relates to a surface treatment method for a polymer film and to a use of a surface treated polymer film according to this method in the production of packaging material, in particular food packaging. The surface treatment method for a polymer film comprises providing information about at least the polymer film to a surface treatment device (102), adjusting at the surface treatment device at least one of a discharge of ions and a residence time of the polymer film in the surface treatment device based on the information (103), and applying the discharge of ions to a surface of the polymer film during the residence time of the polymer film in the surface treatment device to obtain a treated surface of the polymer film (104).
