Unbleached softwood pulp is a type of cellulose fiber derived from softwood trees, such as pine and spruce. This pulp is produced through a chemical or mechanical process that breaks down the wood fibers, resulting in a brownish material that retains its natural color and properties. It is commonly used in the production of paper products, including newsprint and kraft paper. Unlike bleached pulp, unbleached softwood pulp does not undergo chemical whitening processes, making it more environmentally friendly. Its natural color and strength make it ideal for applications where durability is essential. Additionally, it is often favored for its sustainability, as it can be sourced from responsibly managed forests.
