| Speciallity |
| PE, a thermoplastic resin obtained by polymerization of ethylene. In industry, the copolymers of ethylene and a small amount of alpha olefins are also included. Polyethylene is odorless, non-toxic, feel like wax, has excellent resistance to low temperature performance (minimum temperature can reach -70 ~ -100 C), good chemical stability, erosion resistance to most acid-base (not resistant to oxidizing acid), insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation properties; |

| 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 |
| HDPE 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. |
