New PM 71 and PM 72 increase packaging paper production at Shanying Suzhou
- PM 71 will produce up to 350,000 tons of corrugating medium annually
- Hybrid former ensures high quality at high speeds
- Dual start-up of PM 72 and PM 71 now complete
- Voith technology supports Shanying in expanding capacity
Shanying Suzhou Paper has successfully started paper production on its new PM 71 in Suzhou, west of Shanghai. Together with the sister machine PM 72, which recently went into operation, this double start-up marks another milestone in the partnership between Shanying and Voith.
With the new machine supplied by Voith, Shanying is significantly expanding its production capacity in the premium packaging segment. In addition, the company can respond more quickly to market developments and strengthen its position in the growing market for packaging papers.
“We work closely with our customers and tailor our solutions to their strategic goals,” says Carlos Lin, SVP Order Execution & Operations at Voith Paper Asia.
This customization is also reflected in the design of PM 71: The machine was developed for a speed of 1,300 meters per minute and a wire width of 9,300 millimeters. It produces up to 350,000 tons of lightweight but strong corrugating medium per year – with basis weights ranging from 50 to 90 g/m². Together, the two machines will be capable of producing up to 800,000 tons of corrugating medium in the basis weight range of 50 to 120 g/m².
The project features state-of-the-art technology from Voith’s XcelLine including a MasterJet Pro headbox, DuoFormer D II and DuoCentri NipcoFlex shoe press. The hybrid former concept ensures consistent paper quality and low energy consumption even at high speeds. Single-tier dryer sections in the pre-dryer and after-dryer section increase runability. The system is complemented by a SpeedSizer AT film press and MasterReel reeler. Digital systems such as DCS, QCS and OnCare.Health ensure efficiency, quality and low operating costs.
Many components were manufactured locally, enabling faster delivery and installation. “The teams from Voith and Shanying worked closely and professionally together,” reports Hao Mingjin, Production Manager at Shanying Suzhou.
Shortly after commissioning, the PM 71 met the partners’ expectations: stable production conditions with consistent cross-profiles and high-quality finished paper rolls. Both partners aim to continue setting innovative and sustainable standards in packaging paper production in the future.

Voith celebrates over 40 years of NipcoFlex technology
- Since its introduction in 1984, NipcoFlex technology has proven itself in over 700 shoe press installations worldwide.
- The technological advantage of the shoe press lies in its high press impulse and optimal pressure gradient, which enable maximum production output and quality.
- NipcoFlex technology minimizes specific energy and production costs, enables high production speeds and ensures efficient drainage.
- Voith combines mechanical components and high-performance press shells in a complete package for maximum performance.
Full-line supplier Voith celebrated the 40th anniversary of its revolutionary NipcoFlex technology, which has proven itself in more than 700 shoe press installations worldwide since its introduction in 1984. This groundbreaking technology has permanently changed the paper industry by ensuring maximum production output and the highest quality standards.
“The introduction of NipcoFlex technology marked a turning point in paper manufacturing,” explains Dr. Michael Weiss, Chief Technology Officer at Voith Paper. “Our customers benefit from individually adjustable pressure distribution in the press nip, a very wide range of production areas and significant energy savings. The continuous development of this technology is a testament to our commitment to innovation, quality and sustainability.”
NipcoFlex technology is characterized by its simple and reliable design. The high press pulse to which the paper web is exposed, combined with a long dwell time in the nip and optimal pressure gradients, ensures maximum dewatering performance and minimal re-moistening of the felts. Key features include the design of the hydrodynamic pressure shoe with upper and lower parts and an insulating layer in between. Due to its very low bending stiffness, this ensures excellent line force profiles. The hydrodynamic lubrication gap allows for a continuous and uninterrupted pressure increase, thus preventing damage caused by contact between the shell and the pressure shoe. Reliable and well-designed systems – for jacket pre-tensioning, mounting and adjustment, for example – ensure easy handling of the machine in all operating situations.
“The reliability and efficiency of NipcoFlex technology have significantly improved our production processes,” says Günter Leitgeb, Mill Manager at Smurfit Westrock Nettingsdorf. “We have been relying on NipcoFlex for more than 40 years, and it is an integral part of our production. Reliability, easy handling and top performance for over four decades.”
“With our NipcoFlex technology and the associated QualiFlex high-performance press sleeve, we offer our customers an unbeatable complete package for maximum performance,” adds Benjamin Kitze, Director Product Group Press at Voith Paper. “We are proud of our achievements over the past 40 years and look forward to continuing to play a key role in shaping the future of the paper industry.”
Voith is currently developing the next generation of shoe press technology. The focus is on energy savings, improved maintenance and increased performance of felts and covers throughout their entire life cycle. The first important step in this direction is the development of the HighPerformance Press.
The HighPerformance Press concept reflects the absolute focus on resource-saving production. An initial installation is already showing savings of over 4 percent in steam, and an upcoming reference will demonstrate similar savings. Additional features, such as a smart hydraulic unit and reduced drive power also focus on sustainable production, while overall performance and maintenance handling are continuously optimized.
The focus is not only on new installations; existing systems can also be significantly improved in terms of energy efficiency in the future using the new concepts.
