    High-performance Extrusion lines for encapsulation film
    At the production of PV Solar panels, EVA film is used for encapsulation of cells.
    In order to process this EVA film, special properties have to be fulfilled, e.g. low shrinkage or better no shrinkage.
    This is a real challenge for the extrusion process. Standard extrusion lines only allow a very low processing speed. At speed over 5m/min a high shrinkage of the film can occur so that a further processing of this film is no longer possible.
    Reason
    Since the regular extrusion system is limited to a certain speed/output, Breyer developed a profitable system for the production of EVA film and other gluey materials.
    The system allows much higher speed and therefore higher output compared with typical extrusion systems.
    The process allows an almost shrinkage-free production of solarfilm at high speed!!! Especially gluey materials like EVA can be processed easier on this system compared with a calender/cast film unit.
