Unbleached kraft linerboard is a type of paperboard or paper product used in packaging and manufacturing. It is made from kraft pulp, produced through chemical pulping using softwood trees like pine and spruce. Unlike some other paper products, unbleached kraft linerboard retains its natural brown or tan color as it doesn’t undergo a bleaching process. This characteristic makes it strong and durable, ideal for protecting goods during transportation and storage, as well as for applications requiring stiffness and stability, such as corrugated cardboard boxes. Additionally, its sustainability is noteworthy, as it reduces the need for chemical treatments and is recyclable, contributing to environmental conservation. Unbleached kraft linerboard is versatile and finds use in various industrial and commercial settings, including packaging materials like paper bags and protective packaging.
