Natural Brown Kraft Paperboard: A Comprehensive Guide
Natural Brown Kraft paperboard is a strong, eco-friendly material made from wood pulp. It keeps its natural brown color because it’s not bleached, making it sustainable and recyclable. The name “Kraft” comes from the German word for “strength,” highlighting its durability—a quality recognized since its invention in the 19th century by German chemist Carl F. Dahl.
