Abstract

The invention relates to a method for producing a receiver material (10), comprising the method steps of: a) producing or providing a planar film element (12) having a first film surface (14) and a second film surface (16), the planar film element (12) being at least partially made of a film material, the film material comprising: i) one or more silicone rubbers, and ii) one or more fillers, and the planar film element (12) having an adhesive force on the first film surface (14) in the range of 0.5 cN / cm to 120 cN / cm, measured according to the test method J0PMA002 on the basis of DIN EN 1939:2003; b) producing or providing a base substrate (18) having a base substrate surface (20); c) bringing the second film surface (16) into contact with a plasma in order to obtain a plasma-activated second film surface (16); d) bringing the base substrate surface (20) into contact with a plasma in order to obtain a plasma-activated base substrate surface (20); e) applying the plasma-activated second film surface (16) of the the film element (12) to the plasma-activated base substrate surface (20) of the base substrate (18) in order to obtain the receiver material (10), the surface of the receiver material (10) being formed partially by the first film surface (14).
