Unbleached and uncoated kraft paper is designed with two layers that provide exceptional strength and durability, using less virgin wood fiber. It is also visually appealing with its natural brown appearance. However, its highly textured surface may cause issues with printability. To overcome this, it can be treated the same way as bleached paperboard, by using coatings or films to create a printable and water-resistant surface.
