The films do not have a carrier sheet, which would support the application. But merely a protective film for the adhesive side.
The strip for the peeling of the protective film can be had from the material of the film and good hand. Unfortunately, the punching is a predetermined breaking point, which can act too quickly and the strip breaks off.
