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 porocts 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.

| Materials introduction | |
| PEVA is polyethylene vinyl acetate, which is made up of two kinds of materials, PE and EVA, with good flexibility and little elasticity. The higher the proportion of PE is, the harder it is to adhere. It is usually used as the production film. These two chemicals ratio can be adjusted to meet the needs of different applications, and vinyl acetate (VA content) content is high, its transparency, softness and toughness will be relatively increased. | |
