Bubble mailer bag Is for express delivery industry,so called bubble envelope, by polyethylene bubble cover combined with PET or kraft paper , not only have the characteristics of general express plastic bags, but also has more thick buffer layer, provide higher level protection for objects in the package, in addition has heat insulation, sound insulation, moisture-proof, extrusion, impact of the advantages.
The color of the Bubble mailer bag generally pointed by the customer, mostly for the company's signature color, such as DHL generally use yellow, ups use grey, fadex with purple and orange, SF uses the gray. Uniform color express bubble bag can establish a company's professional image, highlighting the strength of the company.

|At present, most of the express bags are waterproof and confidential.
Conventional: Plastic delivery bags, the material is mainly PE, or PO/PE coextrusion film. The domestic use of PE is much more, and the latter is more common in Europe and North America. But whatever it is, it's waterproof, and it's all a one-off seal.

|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.|
