Cheng Loong Has Valmet Supply Key Technologies for Board Machine

Valmet (Espoo, Finland) will supply Cheng Loong Binh Duong Paper (Taipei, Taiwan) with key process technology for its new BM 1 containerboard machine to be located at the company's Ben Cat mill in Binh Duong Province in Vietnam. Valmet's delivery includes a headbox, forming and press sections, a winder, and quality measurement system.

The 6,250 mm wide (wire) BM 1 will produce recycled fluting with a basis weight range of 90 - 180 gsm at maximum speed of 1,000 m/min. Production of BM 1 is 260,000 metric tpy.

Cheng Loong decided to invest in this new recycled containerboard mill and box plant aiming to tap into Vietnam's growing packaging demands. Startup of the greenfield machine is scheduled for the beginning of 2018.

"The containerboard market is growing globally, driven by increasing e-commerce and new packaging applications. Valmet has developed a number of excellent solutions to meet the market needs. Energy efficiency, high board quality, and very good productivity are among the most important highlights of Cheng Loong's board machine," said Jari Vähäpesola, president of Paper Business Line division, Valmet.

Valmet's delivery for the new containerboard machine will include equipment for the approach flow system, a new OptiFlo fourdrinier headbox to ensure higher productivity, OptiFormer Hybrid forming section with blade technology, and a center-roll based OptiPress press section with modern shoe press technology for high dryness to improve energy efficiency. The forming section is equipped with a VacuMaster high-vacuum suction box to significantly improve dryness, thus, energy efficiency. The OptiWin Drum two-drum base winder has a high capacity to meet the production needs of BM 1 and it is also easy to operate. The delivery will also include a Valmet IQ quality measurement system to optimize production process and to maximize production.

"Cheng Loong wanted to have a reliable supplier with high-level technology for its greenfield machine. Technology-wise, a headbox and forming and press sections are key solutions to secure high energy and production efficiency in containerboard manufacturing. A reliable winder with high capacity is essential for such a containerboard machine. With earlier successful deliveries to Cheng Loong (the latest in Taiwan), Valmet has proved to be able to respond to Cheng Loong's needs," commented Petteri Soini, senior sales manager at Valmet.
