Here are the common types of paper in use, which shows the versatility of paper as a product:Īcid-free paper is created using a alkaline production process that removes the lignin from the wood pulp and treats the pulp solution with a mild base such as calcium bicarbonate, to produce a pH that is above 7. Besides the use of paper for printing and publishing, the product is used to protect and package other goods, to record transactions or events, to provide decoration, and to act as carrier or substrate for other materials, to name some its uses. There are many types of paper used in the world today. In the sections below, this article will summarize 33 of the common types of paper and describe their uses or applications. Occasionally paper will go through the process more than once as it's created, used, shredded, recycled, and remade. Before being wound into reels or cut into standard sheets, any desired coatings, pigments, and binding agents are applied. The sheet then passes through a series of presses and dryers to extract excess water content, and then onto a calendaring operation to smooth out the paper. Once the raw pulping is completed, the fiber is cleaned and injected onto a flat wire section where the fiber begins the process of spreading out and forming into a wide sheet. Paper is created from wood pulp that is typically created using a mechanical pulping process that grinds wood logs mixed with water or using a chemical pulping process to remove lignin. Coniferous trees are fast-growing trees that are characterized as having cones and needles as opposed to deciduous trees which have leaves that are shed during the autumn and winter seasons. Paper is a versatile product that is created most often from wood pulp, usually derived from softwood coniferous trees such as pine.
