Methods and apparatuses for coating a flexible substrate are provided. The flexible substrate is guided over a process roller. The flexible substrate has a first protective film, which is removed from the flexible substrate before the flexible substrate reaches a coating zone of a coating device located opposite the process roller. The first protective film is removed from the flexible substrate after the flexible substrate has formed a mechanical contact with the surface of the process roller. A second protective film is applied to the coated side of the flexible substrate after the flexible substrate has left the coating zone of the coating device and before the mechanical contact between the process roller and the flexible substrate is ended.

A transparent plastic film for screening electromagnetic waves includes a transparent film substrate and a layer system comprising at least one silver layer and two niobium oxide layers. The silver layer is embedded between the two niobium oxide layers.
