Between the panes there are composite plastic foils - also called composite foil in the following - from one or more layers. Safety glasses from only one disc with composite film on one or both sides are also known. As a composite film usually Polyvinylbuyrol films are used.
  • VSG The VSG is scratched and broken from both sides. Thereafter, the glass is clamped and the film is stretched mechanically with great force until a gap between the glasses to be separated is formed, in which a knife dips and cuts through the film.
