Product Description

Quad Seal Gray Poly Mailer Bags For Courier Services Company 4"X8" #000


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.
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.
Online shopping outbreak of type growth gave birth to the vigorous development of Poly Malier bags industrial chain, enterprises and individuals are increasingly attach importance to product packaging, online shopping transactions because of transport problems lead to broken parcel everywhere, so the disputes are increasing, for my company will continue to increase investment, development of the Poly bag a variety of high-quality, low-cost, also my company and other types of Poly Malier bags, such as: contained liner coated bubble bag, containing the metal foil vacuum bag, with anti electrostatic shielding bag, conductive bags, welcome customer inquiries from all walks of life.



The cooling method is together. No pollution, high barrier, strong function, low cost, small capacity ratio, high strength, flexible structure design and other characteristics, so that the production process of food packaging material has no pollution. Heat resistance, oil resistance, strong toughness, pinhole resistance, air tightness, nylon resin transparency and polyolefin resin with excellent moisture resistance, heat resistance, with mature technology and high precision processing technology in a product, the product is in use, fully displays the shelf preservation Paul, taste, long storage period, oil resistant, moisture resistant, high temperature (121 DEG C) and low temperature (50 DEG C), very high strength. Its mechanical properties: barrier property and high temperature cooking performance of oxygen and water vapor have reached the advanced level of similar products abroad. Transparency and flexibility are comparable to other products. In the same kind of product processing technology and product performance in the domestic leading level.
