The cellulose fibers are stuck together with a natural glue called lignin.. When the lignin is removed and the cellulose fibers are separated and reorganized, paper can be made. It's also possible to make paper from a variety of other types of plant fibers, such as cotton, flax, bamboo, and hemp.
The ingredients are combined according to the unique recipe for each particular paper, and the grades are then produced in a way that ensures they have the desired properties. According to this source, pulp consists of cellulose fibers that usually come from pulp wood - which in turn comes from trees. The most common wood types used for pulp are aspen, eucalyptus, birch, pine and spruce. Different types of wood are used because the properties of the fibers vary.
