Paper Making and Testing Technical Services

The Go-To Place for Solutions to Papermaking and Testing Challenges

The mission of the Pulp and Paper Technical Services program is to support our allied industries with high quality, cost-effective services. From small-scale laboratory testing to pilot-scale production of large quantities of pulp or paper from a variety of sources, we are well-equipped for almost any technical challenge related to pulping and pride ourselves on a total customer focus.



We have great capabilities in papermaking at NC State. At bench scale, sheet moulds are available in a variety of sizes, with and without white water recycle. For pilot production of paper, the 12-inch “Wolfpack Baby” fourdrinier permits a cost-effective evaluation of a variety of furnishes and conditions.
