Natural Brown Kraft

Natural Brown Kraft Paperboard is a 100% recyclable material featuring a brown color that comes from a mixture of virgin paper pulp and recycled paper pulp with no chemical additives. This material is commonly used across many industries to maximize sustainability efforts or to create the image of a "natural" product.

  • Contains a high amount of recycled content (up to 100%)
  • 100% recyclable and eco-friendly
  • Bleach-free & chemical-free


Natural brown kraft paper is made from a mixture of virgin paper pulp and recycled paper pulp (up to 100%) and uses no chemicals or bleach in its production process. The lack of chemicals and bleach used in the production process makes this material 100% recyclable and gives it the natural brown color it is notoriously known for. Due to its natural brown color, saturated colors printed on this material will come out muted in tone, and it is recommended to print a layer of white before applying an additional layer of color to ensure the colors do not come out muted. The kraft pulping process can incorporate a mixture of wood species, including pine, bamboo, and other non-wood fibers. Pinewood and bamboo are high in resin content, making them exceptional candidates for producing durable kraft paper. Kraft paperboard is an exceptional choice for businesses looking to take a more significant step towards eco-friendly initiatives as the production of this type of material is self-sustainable, durable, and readily available.
