Ideal Fibers for Pulp and Paper Products

The various paper and paperboard products are made for different purposes and therefore have different product specifications and standards. Printing applications require smooth, low porosity paper with sufficient strength to carry the mineral fillers and coatings needed to obtain opacity and gloss. Paperboard products need stiffness and compressive strength to perform well under stacking loads. As the paper requirements change, so do the preferred characteristics of the pulp fibers and the ability of the papermaker to adjust for unfavorable fiber form. Pulping processes also differ in ability to handle diverse tree species. In particular, the mechanical pulping processes are highly species dependent, favoring low-density softwoods with fine fibers and thin cell walls.
