Pine wood is moderately resistant to decay and insect attack. It is used for lumber and pulp make kraft paper, paper board, and book paper. Pine trees have a resinous sap which is used to make turpentine and pine tar.

Paper fiber type: Softwood. Using transmitted light microscopy, pine fibers are identified by the presence of pinoid or fenestriform pits. Hard pines can be distinguished by the presence of dentate ray tracheids. See individual species for specific morphological characteristics. Appearance with Graff "C" stain: varies with pulping and bleaching. Average dimensions of fibers: varies by species. Common pulping method: kraft and sulfite.
