In 2019, Klabin decided to make the biggest investment in its 122-year history: the Puma II project, which aims to produce 910,000 tonnes of high-quality packaging paper annually on two paper machines. Besides the project’s size, an interesting feature is that the kraftliner that is being produced in PM 27 uses 100% eucalyptus hardwood pulp. This disruptive innovation, which Klabin believes will strongly propel its growth, goes against the traditional thinking that softwood pulp is required to make high-quality kraftliner.
“This project brings high efficiency, improved corrugator and converting runnability and recyclable packaging solutions to market. All challenges during this innovative project were solved fast by the Klabin and Valmet teams’ collaboration,” says Francisco César Razzolini, Industrial Technology, Innovation, Sustainability and Projects Director, Klabin.
Start-up work involved around 450 people in various places. During this period, a real-time integration system was used to dynamically manage the entire project progress wherever they were. In addition, advanced communication devices and remote support tools brought technology experts from Finland and Sweden into the job, ensuring high collaboration with the project team.
PM27 is a complete Valmet paper machine with an extended scope of supply delivery, including a wide paper machine engineering package. The delivery consisted of equipment for stock preparation system and approach flow system as well as a complete multiply kraftliner machine (PM 27) from headbox to reel, followed by a winder with automated transfer rails and roll handling systems. The delivery also includes air systems for the machine, a hall ventilation system as well as a wet end chemical system and surface starch preparation and sizer supply systems.
The 9,000-mm wide machine is producing high quality kraftliner and whitetop liner with a design basis weight range of 80-200 gsm. The design speed of the machine is 1,200 m/min and the design daily capacity 1,555 tonnes. Below is a video of the start-up.
