Electronic media are increasingly entering modern life, but paper print media are not going to give up their positions. Today, a huge number of magazines are published on a wide variety of topics and directions. For the production of these publications, special quality paper is used.
What paper is made of
The manufacture of all types of paper involves the use of plant fibers - cellulose. This substance is obtained not only from softwood and hardwood, but also from rag mass and waste paper. In the production of some special types of paper, asbestos, wool fibers and other materials are used.
The best raw materials for papermaking are pine, spruce and birch. At pulp and paper mills and mills, tree trunks are cleaned of dirt and bark, and then, on special machines, they are crushed to the state of chips. Consistently going through all the stages of the technological process, the wood turns into small chips and mixes with water.
The resulting mass becomes the main component for making paper products.
To make the paper less absorbent, it is treated with paraffins and resins. Starch glue helps to achieve a smooth and durable sheet surface. For high-quality printing products, whiteness and minimum transparency of the material are important. These properties are provided by additives: talc, kaolin, barium sulfate, titanium dioxide.
Features of the production of paper for magazines
Higher requirements are imposed on paper for magazine products. The required consumer qualities are obtained using different chemical methods of processing the feedstock. For example, chopped wood is boiled by adding acid to the composition. This is followed by the stage of filtration and washing, during which the raw material is cleaned of harmful impurities that reduce the quality of the material.
The sheets on which glossy magazines are printed have a very attractive look. This effect is achieved by coating the material. Coated paper has no roughness because it uses fillers such as kaolin. In the manufacturing process or at the finishing stage, sheets for future magazines are certainly glued with binders.
Sizing protects the web from fiber deformation that can occur during typographic printing.
To make magazine pages delight the reader with smoothness and gloss, the paper is calendered. With this special treatment, the web passes between elastic rollers. This creates special conditions: high pressure and appropriate temperature. The roll-compressed paper web becomes less puffy and obtains optimum transparency. At every stage of processing, magazine papers are subject to rigorous quality checks and controls.
