| Speciallity | |
| The polymer melt polymerization reactor, must be high, medium and low pressure cooling, separation, high pressure gas circulation cooled, separated into ultra high pressure (300MPa) compressor entrance, medium pressure gas circulation cooled, separated into high pressure (30MPa) and the low pressure circulating gas compressor entrance, after cooling, separated into low pressure (0.5MPa) compressor recycling, and melting of high and low pressure polyethylene after separation into the granulator, the water cut, when granulating, enterprises can according to different applications, adding suitable additives, particles by packaging factory. | |
| 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 | |
| LDPE is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction. It shows strong creep under persistent force, which can be reduced by addition of short fibers. It feels waxy when touched. | |
