Setting new standards in film extrusion
PP, PS and PET are the dominant materials in the food pakkag-
ing segment. They are extruded into film in single and multi-
layers. To increase economic efficiency, additional ground mate-
rial from the in-house thermoforming production and recycled
materials are used. Especially in difficult markets with strong
competition, it is helpful to differentiate with special characte-
ristics. Here, too, better quality always pays off.
Since the production cost of the film is largely determined by
the raw material (approx. 65 percent) and not primarily by the
investment in the system, it is extremely important to focus on
high-quality equipment with operational security, which, above
all, saves raw materials and can be quickly readjusted. Drying
PET via infrared technology saves time and energy. Up to 100
percent ground material can be directly processed in the infra-
red dryer. PP and PS can be processed without a drying process.
The combination of well-tried and simple system setup paired
with advanced Breyer technologies that save time and money
makes it possible: fast startup due to the special melt pump
control and fast adjustment of the film thickness with the

total performance of 1,100 kg/h. For the
functional retrofitting of the system,
Breyer offers a number of progressively
conceived building blocks that save time,
raw materials and, hence, money all of the
required preconditions for economically
efficient film extrusion.
On the Breyer ThermoFlex system in
co-extrusion version for 3-layered film, the
fast startup of a PET film system and quick
changeover to different film thicknesses is
possible. Pure recycling material can be
processed with a 120 mm single-screw
extruder and a 60 mm co-extruder with a
