co-extruded poly mailer,
poly mailers envelopes bags
Strong And Tough Poly Mailer Bags With Logo For Apparel 115x210mm #B
widely used in express or logistic transporting
The bags contains a flap which has a hot melt adhesive strip for easy&permanent closure.and designed an open “one side flap” for protecting goods security,which an adhesive that is applied to the seal flap and is covered with a release liner. When the envelope is ready to be sealed, the release liner is removed to expose the self-adhesive tape.
The superposition of the superposition model head layer, the melt flow in each flow channel, the change of the number of layers will not affect the size of the inner and outer diameter of the head. Its working principle: the molten material from a central feeding hole after entering is first divided into eight shares or sixteen streams, then arrive at the starting point of each material channel eight or sixteen threads in the axial feed annular gap in each strand melting beam was also split into two streams formed in H2 flow on the Q2, and the spiral flow in the spiral groove of the forward flow, as shown in figure. In the direction of extrusion, Q3 is getting less and less, on the contrary, more and more Q2 sides are.
|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.
