Hardwood Kraft Pulp

Unbleached Hardwood Kraft Pulp is commonly used in paperboard and specialty paper, as well as coated and uncoated papers and tissue. In many applications hardwoods pulp provides excellent strength and surface properties.

Overall, hardwoods contain more cellulose and extractives, and less lignin, than softwoods; as well, they usually have a higher initial brightness. For pulp purposes, softwood fibers are, on average, more than three times the length of those contained in hardwoods (thus the origin of the terms “long-fiber pulp” and “short-fiber pulp”).
