Kraft paper tubes, also known as kraft cardboard tubes, kraft paperboard tubes, or kraft paper tubing, are cylindrical containers crafted from robust kraft paper. This material, renowned for its natural brown hue and exceptional strength, is derived from wood pulp using the kraft process. These versatile kraft cylinder packaging solutions are formed by tightly winding multiple layers of kraft paper around a mandrel, creating a rigid and durable structure. Often referred to simply as kraft tubes or kraft packaging tubes, they are a cornerstone of modern, sustainable packaging across countless industries.
