Breyer Extrusion

Extrusion Lines for Optical Films

OptiFlex Lines

The manufacturing of a film is nothing special. However, the creation of a high quality polished flat film of minimal thickness is a different matter altogether.

With the BREYER OptiFlex line you are staying always flexible.

Both side polished, mat and structured film with optical properties can be produced.

The production of ultra-thin, low-tension films of high optical quality in particular, is quickly separating the men from the boys. We can boast an unbeatable combination of superior know-how, gained over many years and excellent extrusion technology.

Thanks to our special calender techniques, tensions in these films can be kept to a minimum. 

The particularly precise, reproducible adjustment of the roll gap combined with the high stability of the calender rolls is an essential prerequisite for the successful production of minimum film thicknesses.

It is not without reason that people rely on BREYER technology time and time again. And of this, we are more than a little proud.

Complete Solution for Optical Film Extrusion


Created with Sketch.

One of the core components of every extrusion line is and remains the extruder itself. From the start, BREYER relies on quality and sophisticated technology.

BREYER extruders are single-screw machines with high efficiency. Most thermoplastics are processed. The extruders are available in the following sizes: 30, 35, 45, 60, 75, 90, 105, 120, 150, 180, 200, 250 mm screw diameter.

The discharge capacity is depending on the size up to 2000 kg / h.

Our specialty is extruders with vacuum degassing . These extruders work particularly economically, since the energy efficient pre-drying of the granules omitted. By separating the remaining monomers, the quality of the melt and thus of the end product is increased. The extruders also have a high specific output. The machines also work reliably in the ejection areas, where other manufacturers must already be dried.

Energy savings
BREYER extruders are designed in such a way that they require very little energy during operation.

The control cabinets are equipped with a Siemens control as standard. The operation is conveniently carried out on the color display. Equipped with solid state relays, single current measurement for each zone, durable ceramic heating tapes (with fast connection plug-in connection), safety temperature monitoring and detailed error analysis.

Three-phase motors are used for the drive technology. On request, particularly quiet running, water-cooled motors are used. Likewise, high-torque motors without gears are available as direct drive in various sizes.

High customer value

  • Brushless, maintenance-free drive technology
  • High specific output
  • Low energy consumption
  • effective degassing
  • No pre-drying necessary
  • Compact size

Flat Sheet Dies

BREYER flat sheet dies are developed with state-of-the-art software, built in 3D design, and manufactured on CNC machines. They get their high-quality finish through the selection of materials and coating depending on the application, combined with a professional polish. Decades of experience and control of the complete extrusion process enable this perfection.   


The program includes single layer and multi-layer dies, with widths of up to 2800 mm. The dies are used for manufacturing flat films (typical thickness range of 0.05 - 1.5 mm) and also for sheet production (thickness of 1 - 25 mm).

All common thermoplastics as well as so-called engineering plastics can be processed. BREYER dies are used in BREYER extrusion lines but also in systems from other manufacturers.

BREYER film and sheet dies are available with the following additional equipment:

  • Rapid lip gap adjustment
  • optimised die shape
  • Restrictor bar
  • Deckling systems
  • Collision protection
  • Thickness measuring systems
  • Control system
  • Die suspension
  • Die carriage

A system is only as good as its components.This especially applies to extrusion lines. For this reason, we at BREYER have given special attention to each and every component of the system – especially calender technology. It is decisive for the final quality and performance of a system. Our specialists have come up with innovative solutions for the drive system, which avoids surface distortions or lateral marks.
