Coating is an essential process in paper manufacturing where special materials are applied to paper to improve its properties. Think of it like adding a protective layer to make paper better for specific uses. This process can make paper glossier, more water-resistant, or better for printing. It's similar to how paint protects walls, but for paper products. When someone mentions coating in paper production, they're talking about this enhancement process that can involve different materials like clay, calcium carbonate, or special chemicals to achieve specific paper qualities.
