Dhunseri Poly Films Private Limited, a wholly owned subsidiary of Dhunseri Ventures, is expanding its cooperation with Brückner Maschinenbau through another investment in polyester film technology. The company has ordered a BOPET film production line with a designed and constant operating speed of 700 m/min for its plant in Panagarh, West Bengal. According to the project partners, this is the world’s fastest BOPET line and the first solution of its kind in the global polyester film industry. The new installation is intended to deliver a significant increase in output while reducing unit manufacturing costs, thereby strengthening Dhunseri Poly Films’ position in the Indian BOPET market. The investment continues the cooperation between the two companies after the start-up in 2023 of the first joint BOPET line in Panagarh, equipped with a multi-gap MDO unit for high-temperature stretching and the FOK 8.8 chain track system designed for high-speed operation with reduced maintenance costs.
New BOPET line with a speed of 700 m/min
The BOPET line planned for Panagarh is designed to operate at a production speed of 700 meters per minute, which in the current market landscape places it among the leading solutions for polyester films. The constant level of this speed declared by the partners is expected to translate into a high volume of finished products and more efficient utilization of the installation compared with commonly used lines operating at lower speeds.
Representatives of Dhunseri Ventures and Brückner Maschinenbau emphasize the significance of this investment for the further development of the BOPET segment in India. The new line is intended to increase production capacity while keeping costs under control. The companies indicate an expected higher film output combined with lower production costs, which should support improved competitiveness of the Panagarh plant.
Continuation of cooperation between Dhunseri and Brückner Maschinenbau
The new order is an extension of the existing cooperation between Dhunseri Poly Films and Brückner Maschinenbau. The first joint BOPET line in Panagarh was commissioned in 2023 and, according to the project partners, proved to be a technical and operational success. It incorporates, among other features, a multi-gap MDO unit designed for high-temperature film stretching and the advanced FOK 8.8 chain track system.
These solutions are intended to enable high film transport speeds and reduce maintenance expenditures by lowering the operating loads on guiding components. The application of similar or further developed technical concepts in the new investment is expected by the partners to deliver an even higher level of efficiency and process stability.
Producer expectations and impact on the BOPET market in India
According to Dhunseri Ventures’ chairman, C.K. Dhanuka, the investment is a response to the projected growth of the polyester film market in India. He emphasized that the company’s objective is to prepare for the expected increase in demand by expanding and modernizing its machinery base.
"We want to be fully prepared for the anticipated growth in our industry. Following the successful start-up of our first BOPET line in 2023, we are excited to continue working closely with Brückner on this new project," said C.K. Dhanuka.
On the Brückner Maschinenbau side, the importance of the contract is commented on by Johann Kreilinger, Head of Sales Middle East, Subcontinent & Africa. He pointed out that the joint project represents an important technological step for the entire BOPET film sector.
"Together, we are setting a new benchmark with the world’s first BOPET line designed for a production speed of 700 meters per minute, a true milestone for innovation and leadership in the industry," said Johann Kreilinger.
Technological elements of the first BOPET line in Panagarh
The first Dhunseri Poly Films BOPET line in Panagarh, implemented in cooperation with Brückner Maschinenbau, was equipped with a number of technical solutions intended to ensure stable production at high speeds. One of the key components is the multi-gap MDO unit for film stretching at elevated temperatures. The use of this configuration is aimed at achieving the desired mechanical and optical properties of the film while maintaining process repeatability.
Another important subsystem is the film guiding arrangement in the form of the FOK 8.8 chain sliding track. It is intended to enable high line speeds while limiting wear on moving parts, which according to the companies translates into reduced frequency of service operations and lower maintenance costs. The newly ordered line is expected to build on the experience gained from operating these solutions at an even higher level of production speed.
According to the partners, the project in Panagarh sets an important reference point for BOPET film producers who are planning to modernize their machinery base or build new production capacities on the Indian market.
