Poly bubble mailers
The mailers packaging mainly including the mailing bags, bubble
mailers and padded envelopes.
The mailing bag is a general designation, which included may kinds
of materials and many kinds of structures, the materials including
the PE, PET, OPP, PVC, Aluminum, stell, paper etc. the structures
including single layer, double layers and multiple layers.
Poly bubble mailers, which is characterized by temporary package to
be transferred in a variety of vehicles, parcel will be stacked
with each other, squeezing. Poly bubble mailers can be divided into
ordinary plastic bags, paper envelopes, bubble envelopes, Poly
bubble mailers, woven bags and so on.
Ordinary plastic bags are made of low-density polyethylene, there
is also a high-density polyethylene, a large amount of Poly bubble
mailers, light weight, small size, attached to the package weight
and small size, ideal for less demanding products to transportation
such as clothing, footwear, jewelry, and other debris.
Courier envelope document mainly paper, divided into white paper,
white card, cardboard and other cattle, paper surface usually

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. |
