Bird’s eye view of Liansheng Pulp & Paper, Zhangzhou
With an already successful portfolio of packaging paper under its belt, Liansheng Pulp & Paper recently took the courageous decision to launch into the tissue market to continue its forward-looking mission of growth into the paper industry. To underpin its entry into the market, ANDRITZ was chosen to supply two tissue lines TM1 and TM2, to the company’s Zhangzhou mill which started up in April 2023. The start-ups symbolized a milestone in Liansheng Pulp & Paper's breakthrough into the tissue industry.
Now, with its strategic planning and corporate development through continuous innovation, Liansheng Pulp & Paper is already making its mark in the tissue market by creating a comprehensive portfolio from packaging to tissue paper grades. Furthermore, ANDRITZ's innovative technologies and solutions have brought Liansheng Pulp & Paper more comprehensive and competitive tissue paper production equipment, with significant energy consumption reduction and production efficiency enhancement and setting a new benchmark for green development in the industry.
The company has already successfully launched its own brand of tissue products, "Senbao," which includes a variety of product series and grades of facial, toilet, napkin and kitchen towel products. As the dedicated brand for Liansheng Pulp & Paper’s entry into the tissue market, "Senbao" symbolizes "the treasure of the forest," with a product concept that emphasizes "virgin pulp from nature”. The products feature a soft touch and gentle texture, fully reflecting Liansheng Pulp & Paper's humanistic care for consumers and its focus on nature and health. With high-quality, environmentally friendly characteristics, and a diverse product line, the company is committed to meeting the complex needs of end consumers for daily-use tissue paper, creating a "Forest · Pulp · Paper · People" green ecological community, and standing out in the competitive domestic tissue market.

In recent years energy saving and consumption reduction have been key indicators for paper manufacturers to maintain sustainable development and competitive advantage. ANDRITZ PrimeLine tissue sustainable production has been proved effective in every step of daily operation. When talking about the energy consumption of these two tissue machines, Hua and Wei comment, "The two tissue machines are equipped with suction pressure rolls which have no additional hydraulic units needed when compared to shoe presses, resulting in significant electricity savings. The drives also have low electricity consumption, thus ANDRITZ has done a great job in reducing overall energy consumption. In addition, ANDRITZ's heat recovery system is better than other makes of similar machines, making incredible energy-savings when applied with the suction pressure rolls. The suction pressure rolls can achieve a post dryness of 42%, ensuring both dryness and the bulk of the tissue, reducing cost while ensuring excellent paper quality."

To reduce the raw material cost for tissue manufacturers, ANDRITZ has recently introduced a high-consistency refining system in stock preparation for tissue, aiming to reduce the proportion of long fiber while ensuring paper strength. Wei also gives a positive evaluation of the actual application of the high-consistency refining system, he says, "ANDRITZ's high-consistency refining system is very helpful for our goal of reducing long fiber use. If we did not use the high-consistency refining system, the use of long fiber would have to increase by at least 5-10%. Long fiber savings are quite significant for us in terms of cost savings."

ANDRITZ has vast experience in double-width tissue machine technology, which is favored for its high efficiency, stability, and convenient maintenance and operation in more than 30 Chinese domestic references. These unique advantages have been fully demonstrated in the Liansheng Pulp & Paper TM1 and 2 project. Hua comments, "From a daily operation perspective, the stability of these two tissue machines is really good, and the machine efficiency is also excellent." Wei adds, "The current machine efficiency can reach around 98%. These two tissue machines with suction press rolls make operation and maintenance more convenient and cleaning of the felt easier. Convenience of operation is very important for paper makers, team leaders, and even supervisors in the workshop. Machine efficiency is also one of the KPIs for workshop assessment. It has an impact on labor costs, which will also affect the subsequent development of the project and the efficiency of whole operation."
"As a large manufacturing enterprise in the pulp and paper industry, ANDRITZ expertise and know-how are undoubtable,” Wei continues, “During the optimization, the ANDRITZ team provided a lot of support and constructive ideas from a technical, personnel, and company perspective."
Looking forward to the future, Hua fully affirms ANDRITZ's technical strength and service quality and looks forward to further deepening cooperation between the two parties in the near future. “It is exciting to have ANDRITZ bringing more energy-saving and carbon-reducing innovative technologies to the industry. Shoulder to shoulder with each other, we look forward to a win-win situation in a high-quality green transition in the paper industry.”
ANDRITZ and Liansheng Pulp & Paper have forged a strong partnership marked by innovation and environmental stewardship. Established in 2020 as part of the Liansheng Paper Group's expansion into household paper production, Liansheng Pulp & Paper is Fujian's premier packaging paper manufacturer, renowned for its commitment to eco-friendly manufacturing practices. Through collaborative efforts, ANDRITZ has supported Liansheng Pulp & Paper in achieving operational excellence, enhancing production efficiency, and maintaining stringent environmental standards. This partnership exemplifies a shared dedication to sustainability and cutting-edge solutions in the paper industry.
The PrimeLineTM W 2000 tissue machines are engineered for high performance, featuring a design speed of 2,000 m/min and a working width of 5.65 m. They incorporate advanced energy-saving technologies, including 20 ft. PrimeDry Steel Yankees and steam-heated hoods, ensuring optimal thermal efficiency. The performance of an ANDRITZ steel Yankee exceeds that of a cast-iron Yankee of the same size. Steel Yankees have an evaporation rate that is 15-20% higher than cast-iron models, which results in 8-10% better machine performance.
The stock preparation systems are optimized for NBKP (Needle Bleached Kraft Pulp) and LBKP (Leaf Bleached Kraft Pulp), leveraging FibreSolve FSV pulpers, a pulp screw press, and HC refiners to deliver consistencies of 25%-30% while maintaining exceptional fiber quality. Additionally, the systems encompass advanced approach flow solutions, broke handling, and a comprehensive fabrics and rolls package—featuring state-of-the-art forming fabrics, press felts, and roll covers—to ensure superior dewatering efficiency and reliability at high operational speeds.
