Sack Kraft Paperis a porouskraft paperwith highelasticityand high tear resistance, designed for packaging products with high demands for strength and durability.

Pulp produced by the kraft process is stronger than that made by otherpulping processes; acidicsulfite processesdegradecellulosemore, leading to weaker fibers, and mechanical pulping processes leave most of theligninwith the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as thehydrophobicnature of lignin interferes with the formation of thehydrogen bondsbetween cellulose (and hemicellulose) in the fibers.

Kraft pulp is darker than other wood pulps, but it can bebleachedto make very white pulp. Fully bleached kraft pulp is used to make high quality paper where strength, whiteness and resistance to yellowing are important.
