Speed, width, uptime: tomorrow’s film stretching solutions
Advanced packaging and specialty films for efficiency and the highest quality
Brückner Maschinenbau will showcase its latest film stretching technologies at Chinaplas
2026 in Shanghai (Hall 2.1, Stand G54), highlighting the company’s unique combination of
high output, low production costs, and exceptional efficiency.
BOPP – High Output and Future-Proof Concepts
Brückner’s BOPP technology combines a production speed of 700 m/min, a line width of
10.4 m, and an output of 10 t/h, enabling a broad range of high-quality packaging solutions.
This performance profile ensures both high efficiency and flexibility for film producers.
Looking ahead, Brückner is going to introduce a 12 m BOPP film stretching line tailored for
the Chinese market. This next-generation line sets new industry benchmarks in productivity,
efficiency, and quality for commodity film production.
Delivering the lowest specific investment and production costs for film producers, it represents
a highly attractive and future-proof entry into next-generation BOPP production.
BSF – Battery Separator Film Solutions
Brückner’s battery separator film lines are providing with 500 million m² saleable film the
highest output in the industry and ensures a long-term competitiveness.
For high-puncture resistant, ultra-high stretched (down to a thickness of 5 μm) battery separator
films, a dedicated line layout is available.
BOPE – Advanced Mono-Material Packaging Solutions
Driven by sustainability and recycling targets, Brückner has developed an already proven
biax line layout to produce BOPE-HD films. In combination with PE-blown films or even
BOPE-LLD films, it enables 100% PE mono-material packaging.
With this new line layout, higher density and lower MI PE grades can be produced.
BOPET – Superior Productivity for Packaging Films
For highest productivity and efficiency, Brückner is offering BOPET-lines for packaging applications
with a superior production speed up to 700 m/min, facilitated by cutting-edge
chain-track systems.
The sliding chain track system FOK 8.8 enables up to 700 m/min production speed and
is optimized for a film thickness up to 36 μm. Further unique features are the reduced mechanical
complexity, and hence lower maintenance efforts/costs resulting in lowest possible
operating costs.
The roller chain track system FOK 5.9 is Brückner’s latest development with a superior,
patented spring-loaded bearing system for film thicknesses up to 75 μm and a production
speed up to 650 m/min.
Recently, Brückner has sold the world’s first 700 m/min BOPET line to a leading BOPET
film producer in India, which will be in operation within the year 2027.
BOPA – The Widest Lines on the Market
Brückner offers the market’s widest production lines – 8.4 m for sequential and 7.4 m for
simultaneous stretching thanks to Brückner’s unique LISIM® technology – ensuring versatility
for various film stretching solutions.
BOPP-C and -CCCF – Capacitor and Composite Current Collector
Films
Since decades, Brückner’s biax lines for capacitor films and recently also used for composite
current collector films, are the benchmark in film quality and process stability. The
LISIM® technology for simultaneous stretching as well as sequential lines enable the production
of extremely thin films of down to 2 μm for highest energy density in EV applications
as well as thicker films in the range of 6.8-12 μm for HVDC in power transmission, wind and
solar power inverters and all kinds of other electrical capacitor applications.
Specialty Film Lines – Innovative High-Performance Plastics
Brückner Maschinenbau also offers highly customized production solutions for advanced
high-performance plastics such as PTFE, PI, PPS and others. A particular highlight is the
Transverse Direction Orienter (TDO), which operates reliably at process temperatures exceeding
400°C, ensuring maximum stability and precision even under extreme thermal conditions.
To meet the growing demand in Asia, another PTFE film production line specifically
designed for the Chinese market is scheduled to start in 2027.
