Known for its clean white appearance and excellent strength, this paper is produced through the kraft process and then bleached to achieve its distinctive color and uniformity. Bleached kraft paper offers a perfect blend of visual appeal and resilience, making it a preferred choice for companies looking for high-quality packaging solutions.

This process removes lignin, the component in wood that binds fibers together, resulting in strong, flexible pulp fibers. Once the pulp is created, it undergoes a bleaching process that removes residual lignin and whitens the fibers...
