PC panes have a sensitive surface that needs to be protected for as long as possible.
Protective films are therefore already applied after the extruder; on one side as well as on both sides.
During further processing, however, these films are often very disturbing; for example, when the panes are installed or glued into a frame.
Then the film must be removed at the edges; precisely and without damaging the surface.
This is very important when the panes are used in extreme environments – as is the case with cable car gondolas, for example.
In the changing environmental conditions prevailing there, even the smallest damage to the surface would cause the greatest damage over time.
