Food Grade Eco Poly Bubble Mailers Red 7.25"X12" #1 Biodegradable
Acid Resistance
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.

| Materials introduction |
| Aluminum is a silvery white light metal. Ductility. The products
are usually columnar, rod, flake, foil, powder, ribbon and
filiform. A layer of oxide film to prevent metal corrosion can be
formed in humid air. The acid treated aluminum powder heated in the
air can burn violently and emit a dazzling white flame. Soluble in
dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium
hydroxide and potassium hydroxide solution, insoluble in water, but
can react with hot water slowly to produce aluminum hydroxide, the
relative density of 2.70, elastic modulus 70Gpa, Poisson's ratio
0.33. Melting point 660. Boiling point 2327. It is widely used for
its light, good conductivity and thermal conductivity, high
reflectivity and oxidation resistance. Do the daily dish aluminum
is usually called "steel" or "steel". The thermal expansion
coefficient of Al at (25) Shi Wen is 0.0000236mm/ C or 23.6ppm*k-1. |
