Albany, NY/ 08/ - - Uncoated free sheet paper is a grade of printing and writing paper which is free of mechanical pulp, which is a completely chemically treated pulp without any coating on the surface. The Ostrand pulp plant produces 420, 000 tonnes of chlorine- free bleached kraft pulp, which is used in the production of printing paper and hygiene products, plus approximately 90, 000 tonnes of chemically treated mechanical pulp ( CTMP), which is used for the manufacture of hygiene products and packaging products. Wood- free paper is paper created exclusively from chemical pulp rather than mechanical pulp. Chemical pulp is normally made from pulpwood, but is not considered wood as most of the lignin is removed and separated from the cellulose fibers during processing, whereas mechanical pulp retains most of its wood components and can therefore still be described as wood. The primary goals of pulping are to free fibers in wood from the lignin that binds these fibers together, and then to suspend the fibers in water into a slurry suitable for paper making. As the oldest form of pulping, mechanical pulping uses mechanical energy to weaken and separate fibers from wood via a grinding action.
