Types of Trees from Which Paper Is MadeSince wood pulp provides the most important raw material for paper manufacturing, this translates to the importance of trees in the paper industry. Trees from which paper is made are either softwood of hardwood, with softwood coniferous trees forming about 85% of the trees whose wood pulp is vital for paper. Softwood tree types possess longer cellulose fibers which are known to confer adequate strength to paper. This is in comparison with the hardwood shorter cellulose fibers. Major tree types in the softwoods category are spruce, pine, fir, larch, and hemlock. Eucalyptus is a hardwood that has largely been used for paper production. Other hardwoods applied in this industry are oaks, aspen, birch, and maples.
