Poly Malier bags
Polyethylene is a typical thermoplastic, it is a non smelly, tasteless, non-toxic flammable white powder. PE resin molding process is the extrusion granulation of the wax particles, the appearance of milky white. Its molecular weight in the range of 1 in case of Loa million. The molecular weight of more than 100 thousand of the ultra-high molecular weight polyethylene UHMWPE3 F. The higher the molecular weight, the better the physical and mechanical properties, the more close to the level of the requirements of the engineering materials. But the higher the molecular weight, the difficulty of the processing is also increased. The melting point of polyethylene is 100-130C and its low temperature resistance is excellent. Good mechanical properties can be maintained at -60, but the temperature at 80~110. |

Poly Malier bags
Poly Malier bags by single-layer polyethylene composition, with thin, good elasticity, good waterproof performance, characteristics of low prices, is widely used to express small package, the main material for low density polyethylene, color is gray, black, opaque, can better protect client privacy, usually used for wrapping the outer layer, the bag outside Post Express single.
About Poly Malier bags material, need to pay attention to: in the south of China Guangdong area, people called high density polyethylene for PO, low density polyethylene called PE.

| 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. |
