Brückner's unique R&D environment includes our Innovation Test Center (ITC) as well as our Technology Center, both offering comprehensive R&D for all kinds of film stretching technologies under one roof. The Technology Center is rented to our customers and raw material suppliers for film and resin development.
On our unique pilot line many types of film can be produced - in all stretching modes.
Brückner‘s Technology Center includes a uniquely flexibile pilot line. Numerous film types of up to 7 layers can be manufactured in all stretching modes:
The pilot line is the perfect environment for R&D and sample production for BOPP, BOPET, BOPA, BOPS, BOPLA, MOPET-G, MOPS and many other film types. Some of the highlights we produced on our pilot line:
Sequential BOPP 2 - 100 μm 1/3/5/7-layer
Sequential and Simultaneous BOPET 2 - 400 μm 1/3/5-layer
Sequential and Simultaneous BOPA 15 - 35 μm 3/5-layer
Sequential BOPE 15 - 50 μm 3/5-layer
Battery Separator Film 5 - 25 μm 1-layer
Monoaxially oriented film: PETG, PS, Polyolefin 30 - 50 μm 1/3/5-layer
And others: BOPLA, BOCOC, BOPVDF, BOPEN, BOPEEK, BOPC, BOPVA
With our laboratory stretching machine KARO® 5.0 for monoaxial and biaxial film orientation it is possible to test films and sheets in a very simple and economical manner – in the sequential as well as in the simultaneous stretching mode.
It is ready for your use and can be rented on an hourly cost basis:
Newly designed user interface – intuitive & easy machine control
Accurate, reliable film temperatures by circulating air ovens – homogenious film samples
Improved insulation and temperature separation – Perfect process control by accurate temperature balance, stable film quality
Good accessibility – for easy maintenance, less downtime
Moving stretching system through different temperature zones – the same as on film stretching lines conditions close to film production line
For the development of new film formulations or new film types, Brückner Maschinenbau has installed a laboratory extrusion line (LBE) with the following features:
Multi-layer co-extrusion with up to four different polymers for cast sheet production in co-operation with the well-known Fraunhofer Institute for Packaging and Process Engineering. Suitable for tests on the KARO® 5.0 lab stretcher:
Our “Innovation Test Center” is an important part of the professional development process at Brückner Maschinenbau for a number of reasons: We aim to offer our customers proven film stretching line solutions that are absolutely reliable. This also applies in the case of completely new innovative projects even if they are being used in production for the very first time.
We prove our expertise in advance through experiments and measurements on several testing devices:
High-speed clip and track test stands in production environment
Oven test bed and nozzle boxes
Test stand for high-speed roller chains
Nip roll test stand
Test stand for simultaneous stretching systems
