MACHINERY | TECHNOLOGY BOPET BOPET film line runs at 700 m/min
India-based Dhunseri Poly Films has ordered a BOPET film line that runs at 700 m/min – which supplier Brueckner says is “the world’s fastest”. The new line will be installed at the company’s site in Panagarh, West Bengal. “We are setting a new benchmark with the world’s first BOPET line designed for a production speed of 700 metres per minute – a milestone for innovation and leadership in the industry,” said Johann Kreilinger, head of sales for the Middle East, Subcontinent and Africa at Brückner Maschinenbau.

MDO films on show at
Interpack At Interpack 2026 – held in Germany in May – Windmöller & Hölscher (W&H) will showcase a range of sustainable MDO-PE packaging. These include an MDO-PE frozen food pouch for extreme conditions, packaging with printed or extruded barriers, and a 35% PCR stretch film.
“MDO still has the
reputation of being difficult,” said Torsten Schmitz, managing director of the extrusion business unit at W&H. He said that many
film-producing companies have explored MDO in recent years but “not taken the final step”. �

Dhunseri’s performance through higher output and lower production costs. CK Dhanuka, chairman of parent company Dhunseri Ventures, added: “We want to be fully prepared for the anticipated growth in our industry. Following the start-up of our first BOPET line in 2023, we are excited to continue working with Brueckner.” Dhunseri’s first joint BOPET line –
also at its Panagarh site – features technologies such as Brueckner’s multi-gap MDO for high-temperature stretching and the ‘FOK 8.8’ sliding chain track system – for high-speed operation and reduced maintenance.
EXTRUDERS BOPET line uses 360mm screw
BB Engineering has supplied two 360mm PET single- screw extruders to a Chinese customer – which will use them on a BOPET line to produce optical film. BB says this is the largest single-screw for processing
PET on the market. The barrier screw, which is 11.5m long, enables
throughputs of up to 5,400 kg/h. The total weight of the extruder is more than 46 tonnes, and its length is over 14m. Two water-cooled motors, each with an output of 700kW, are used to drive the extruder. The company says the extruders allow “additional possibilities for applications in the high-performance segment”. �
