Voith is the first single company to supply a complete paper production line for a U.S. project.
March 25, 2021
Green Bay Packaging has started operation on its new PM4 production line in US starting March 11, 2021. The facility located near the headquarters of the family-owned company in Green Bay, Wisconsin is a groundbreaking project in several respects. The testliner machine is the first new paper mill built in Wisconsin in over 30 years, creating numerous new jobs in the Lake Michigan region. Moreover, it is the first time in the history of the U.S. that a single company was awarded the contract to supply a complete production line for the paper industry:
The scope of supply of Project WolfPack includes a BlueLine stock preparation line including the wet end process, the XcelLine paper machine, a VariFlex Performance winder and reject handling system. The supplied effluent treatment plant for wastewater treatment rounds off the scope of supply. The overall package includes a multi-year roll and clothing servicing agreement for all sections of the paper machine. Voith also supplied the MCS, DCS and QCS automation solutions.
PM4 has a wire width of 331″ (8,400 mm) and a design speed of 3,937 fpm (1,200 m/min). Green Bay Packaging will use the facility to produce testliner at basis weights between 18 and 56 lb/1000ft2 (88 and 273 g/m2). “Thanks to the new facility, we can more than double our production capacity at the Green Bay site,” says Matt Szymanski, Vice President of Mill Operations at Green Bay Packaging.
Only recovered paper is used as feedstock. Voith equipped the BlueLine stock preparation line with innovative technology that minimizes fiber loss. In addition, the highly purified fiber suspension is important for minimizing web breaks during paper production and thus improving the efficiency of the system. Through its BlueLine stock preparation line and XcelLine paper machine, Voith has created the basis for PM4 to achieve resource-conserving paper production. “Environmental protection is one of our core values,” explains Szymanski. As well as the many components that allow sustainable production on the new facility, an effluent treatment plant also helps reduce water consumption and protects the environment.

Green Bay Packaging and Voith are longstanding partners. Voith has already demonstrated its comprehensive capabilities and technological expertise in numerous upgrade projects, i.e. the Morrilton PM1 in Arkansas. This excellent experience was one of the deciding factors in contracting Voith to build the new production line.
