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.

In order to meet the new demand of food manufacturers for packaging, raw color Kraft boards are different from those of bleached cardboard, such as baked food or convenience food. The natural brown appearance of the original color kraft paper has a healthy and antique flavor. In fact, the distinctive contrast between the unique appearance of the kraft paper and the large amount of white packaging can also make the product more prominent. Because many of the food packaging is designed to provide convenience or practicality, the strength of the kraft paper is another advantage. The outer packing must be strong enough so that the customer's meal can be wrapped without leaving it off. In the same way, the drink cup must be kept in a wet environment so that coffee is not allowed to flow to the customer's thighs. Intensity is also a major consideration for frozen foods, because the packaging of frozen foods can not be deformed, torn, distorted or absorbed too much in the freezing / thawing cycle. In terms of practicality, kraft paper is better than homogenous bleached kraft paper.
