Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process. Sack kraft paper (or just sack paper) is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.
Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers.
Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high quality paper where strength, whiteness, and resistance to yellowing are important.
Paper has long been a standard in packaging for one reason: it just works. With all of the possibilities out there for protection during packaging and shipping, Kraft Paper has stood the test of time and has endured.
- Strength- Kraft paper is durable and can withstand industrial pressures to protect property and materials. Some try to use lesser quality papers, which may have their paper uses, but when it comes to protecting products and materials, the strength of Kraft Paper stands out among other alternatives
- Pallet Uses- Having anti-slip Kraft Paper between layers of boxes, bags and other materials reduces breakage and protects the products being shipped. Using pre-cut sheets makes for palatalizing products even faster, while saving money in the long run by having an added layer of protection. Using a Kraft Paper cardboard slip sheet on the base layer of palliated items prevents entire loads from shifting while in shipment.
- Wrapping Individual Items- Pottery style stores and craft stores use Kraft Paper to wrap items individually because it provides an affordable layer of protection at the fraction of the cost of alternative products. Manufacturers use Kraft Paper to wrap individual items because they want their products to be delivered in one piece and be ready for use by the consumer or end-user.
- Floor Covering- Kraft paper is easy to apply to flooring to protect surfaces during manufacturing as well as construction. Some use Kraft Paper to prevent fiberglass from being ruining flooring. Others use rolls of Kraft Paper to protect their customer’s flooring during contraction and remodeling projects.
- Paint Masking- Overspray from paint can ruin a car, boat, or building. Simply using Kraft Paper to mask items being painted will prevent unnecessary overspray and ultimately save time and money.
The kraft paper market is projected to grow from USD 15.6 billion in 2019 to USD 18.7 billion by 2025, recording a CAGR of 3.0% during the period. The rise in demand for kraft papers in various end-use industries, such as food & beverages, building & construction, cosmetics & personal care automotive, and consumer durables, is a key factor that is projected to drive the growth of the kraft paper market across the globe. In addition, factors such as rapid urbanization across regions and the recyclability feature of kraft papers are projected to contribute to the growth of the kraft paper market.
