Brückner Maschinenbau will showcase its latest film stretching technologies at CHINAPLAS 2026 in Shanghai on April 21-24, highlighting its 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.

Battery Separator Film (BSF)

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

Thanks to Brückner's unique LISIM technology, the company offers the market’s widest production lines – 8.4 m for sequential and 7.4 m for simultaneous stretching – ensuring versatility for various film stretching solutions.

BOPP-C and BOPP-CCCF: Capacitor and composite current collector films

Brückner’s biax lines for capacitor films and 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 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.
