Brief Introduction
Kraft bubble mailers
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.

Materials introduction
The color is yellowish, translucent and lustrous. Transparency is better than polyethylene, polypropylene, poor polystyrene, with the auxiliary dosage is different, divided into soft and hard PVC, soft products soft and tough, feel sticky, hardness of hard goods is higher than low density polyethylene, and lower than polypropylene, in the inflection place will appear whitening phenomenon. Stable; not easy to be acid and alkali corrosion; heat tolerance.
PVC has the advantages of flame retardant (flame retardant value above 40), high chemical resistance (concentrated hydrochloric acid, sulfuric acid concentration of 90%, nitric acid concentration of 60% and sodium hydroxide concentration of 20%), mechanical strength and good electrical insulation advantages.
Polyvinyl chloride has poor stability to light and heat. The softening point is 80, and it begins to decompose at 130. In the absence of heating stabilizer, PVC began to decompose at 100 degrees Celsius, and decomposed faster than 130 degrees celsius. When heated, the hydrogen chloride gas is released, and hydrogen chloride is toxic gas, which makes the color change from white to pale yellow to red to brown to black. Ultraviolet rays and oxygen in the sun will cause the decomposition of polyvinyl chloride, which makes the flexibility of polyvinyl chloride decrease and finally become brittle. From here, it is not difficult to understand why some PVC plastic will become yellow and brittle for a long time.
