| Production process The multilayer head is the forming part of the multilayer film. It is the heart of the whole multi-layer coextrusion blowing device. This product uses a double spiral plane superposition head. Side feed is generally used in the head of the machine. The melt is symmetrical on the central axis and flows on the superposition surface of each layer, not the traditional cylindrical flow. Its advantage is that the number of the head can be combined arbitrarily, the structure is simple, and the temperature of each layer can be controlled individually, so that the temperature of each layer can be controlled individually according to the needs of different materials, and the decomposition of materials can also be effectively prevented. | |
| Brief Introduction | |
| 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. 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. | |
