Brückner Maschinenbau at Finetech 2009

Cutting-edge film stretching technologies for the challenging Japanese market

At the “Finetech Japan” in Tokyo from April 15 - 17 Brückner Maschinenbau GmbH & Co. KG (East Hall No.1, 24-30) focuses on high-end technology for the production of added value films. Japanese film producers will get a deeper insight into:


Simultaneous stretching without mechanical links: LISIM®


Line concepts for optical films for the flat panel display industry and PET thick film up to 400 µm for high value optical and industrial applications

Highest flexibility for a widest range of present and future applications

Contact free stretching for superior surface properties

Clean room suitable

Advanced linear motor technology

Several features for first-class optical films: low bowing and even film properties, low and balanced shrink, high dimensional stability

New: Extension to Brückner`s proven LISIM® technology

Dedicated to small and mid-size production and pilot lines

Utmost flexibility through unique stretching ratios (MD 0.5 – 6.0; TD 0.8 – 5.0)

Wide range of applications, e.g. optical films, retardation films battery and separator film  



Production of high performance BOPET film


Whether focusing on high efficient production of packaging film or getting into the optical film grades up to 400 µm - Brückner offers numerous solutions for BOPET film producers.


Brückner`s MDO technology with soft drive system and online tension monitoring is trend-setting for the production of added value BOPET films. For Highest line speeds and output the MDO 2-gap stretching section leads to unique stretching ratios of 4.5:1 or even above. Thus, compared to the benchmark technology, films with improved mechanical properties in MD direction can be produced.


Technologies for new resins, products & applications


Clean room suitable sequential and simultaneous technologies – mostly used for the flat panel display market: polarizer film, retard film or protection film

Sequential concepts for the processing of high temperature films used within the textile industry, for membranes in the medical sector and for flexible printed circuits and insulations  


Worldwide unique technology center

Pilot line


Wide range of raw materials; PP, PET, PA, PS, PE, PVC, PEN, PLA, PVDF, PEEK, COC and many others

All stretching modes: MD, TD, sequential, simultaneous

Film structures: 1, 3, 5, 7 layers

In-line coating


Laboratory stretcher Karo IV


Comparison of a large number of different materials in a very short time

Transfer of process conditions for comparable film properties

High stretching ratios

Heating capability up to 400°C

MD retardation for optical films


Optical, mechanical, chemical laboratory
