Bisque Kraft Bubble Mailers 295x435mm #J Durable Puncture Resistant
Application
Kraft paper is used in various industries, such as chemical
industry, machinery and so on. It is especially widely used in the
food packaging industry.
Kraft paper use: kraft paper is widely used in various packaging
products, paper bags, handbag kraft paper, color box, gift box
kraft paper, printed kraft paper.
Printed kraft paper, notebook kraft paper, operating kraft paper,
envelope special kraft paper
The packaging of food should follow the principle of convenient and
portable. The anti stretch advantage of kraft paper makes it very
suitable for the packaging demand. In order to prevent the
consumers from carrying out the food, the bag is broken, and the
packaging material requires good tensile strength. The packaging of
the beverage requires a certain ability to resist wetting and
deformability, so as to prevent the damage of water absorption and
deformation.
For frozen food packaging, key using high strength materials as
packaging is also considered, this material must be able to
withstand low temperatures melt ice and the thermal expansion and
contraction, prevent deformation, distortion, wrinkle and excessive
moisture can not hold food. In these respects, the original color
kraft paper is even more suitable than the SBS paper.
Description:
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.
