Encapsulation film produced on regular extrusion lines has naturally a shrinkage which effects not only the process of laminating but can result in destroyed wafers and, therefore, creating waste and thus increased production costs.

A low-shrinkage film allows a smooth and fast laminating process. The more shrinkage a film has the more carefully the warm up procedure must be controlled and could increase the laminating time.

With Breyers new extrusion process, it is possible for the first time to extrude EVA film at a high speed by keeping the shrinkage low. That ensures not only a more profitable manufacturing of film but also an advantage in the sales of such film.
For the module manufacturers, it means that they can run their laminators more stable and as fast as possible by using low shrinkage film.
They will have the advantage of more troublefree production combined with a more reliable and efficient manufacturing by using low shrinkage film. Notable module manufacturers are, therefore, very much interested in getting low shrinkage film.
Since the regular extrusion systems are limited to a certain speed/output, BREYER has developed a profitable system for the production of EVA film and other gluey materials. Beside of the production of low-shrinkage film, the system allows on top much higher speed and, therefore, higher output compared with typical extrusion systems.

EVA film makers are faced to a higher profitability by using the new technology of Breyers extrusion line since the output is much higher.

Cause of the improved properties and performance, this EVA film is about to set a complete new standard in the encapsulation film and its procedure during laminating.

End of January 2010, TUV Rheinland has completed the module test with EVA encapsulation film from Breyer’s line with success.

Availability: The line is developed and produced by BREYER extrusion lines, Germany. http://www.breyer-extr.com/. Contact: Joachim Bormann, email: Joachim.bormann@breyer-extr.com, phone: +49 (0)7731 920119, Kurt Rickel, email: kurt.rickel@breyer-extr.com.
