Kraft paper usually keeps its brown color, suitable for bags and wrapping paper. According to the different nature and use, the kraft paper has a variety of uses. Kraft paper is a general name for paper, and there is not a certain standard. It is generally classified according to its nature and use.
According to the different colors can be divided into: unbleached kraft paper, kraft paper, red white kraft paper, kraft paper, kraft paper, Matt Dan Guang double color kraft paper.
According to the different uses, it can be divided into: kraft paper, waterproof kraft paper, moistureproof kraft paper, antirust kraft paper, kraft paper, kraft paper, insulating cowhide cardboard, leather sticker and so on.
According to the different materials, it can be divided into: regenerated kraft paper, cork paper, cowhide base paper, rough kraft paper, kraft paper, wood pulp kraft paper, composite kraft paper and so on.
Kraft bubble mailers or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process.
Sack Kraft bubble mailers, or just sack paper, is a porous Kraft bubble mailers 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.
