| Waterproof Printed Black Metallic Shipping Envelopes , 180x165
#CD-DCD Custom Bubble Mailers | | | | Speciallity | | The vacuum aluminum plating is in the vacuum state, the aluminum
metal is heated and molten to vaporization. The aluminum atom
condenses on the surface of the polymer material and forms a thin
aluminum layer. Vacuum aluminizing requires smooth surface, smooth
and uniform thickness of substrate, stiffness and friction
coefficient is appropriate, surface tension is greater than 38
Dyn/Cm2, thermal performance is good, it is able to withstand the
heat radiation and condensation heat of evaporation source, and the
water content of substrate is less than 0.1%. Commonly used
aluminized substrates include polyester (PET), polypropylene (PP),
polyamide (PA), polyethylene (PE), polyvinyl chloride (PVC) and
other thin films, and process requirements. | | | | Brief Introduction | Metallic bubble mailers
Product description:
Metallic bubble mailers is made of low density polyethylene (LDPE).
The features of low cost, large volume, good waterproof
performance. Usually we receive the courier package, the package
outside the black or gray bag is the courier bag. LDPE film
flexibility, are not easy to be torn, comparison of bright color
printing, many logistics companies in order to achieve the effect
of publicity will custom printed graphic courier bags. Express bag
also has anti theft special self-adhesive tape, the self-adhesive
posts with a one-time, non recovery characteristics and prevent the
parcel before delivery to the recipient is opened without
authorization, using a very simple and convenient.
Product principle:
Metallic bubble mailers has self-adhesive tape, using a special
glue, as long as mouth closed, then open it will damage opening or
a mark was opened, which is prevention in parcel transport process
is stolen. At the same time the bag is closed, the sealing property
is good, effectively waterproof, sunscreen.
Structure:
The 1 layer is made of pure low density polyethylene film.
Making method:
Metallic bubble mailers use high quality low density polyethylene
material by blow molding equipment to produce Poly film, then
composite with self-adhesive tapes. Finally, making equipment
produce finished bag.
Production process:
The blow molding process, composite process, bag making process
Product parameters:
Thickness of 11 wire size can be customized
characteristic:
1 light weight, large volume.
2 strong flexibility, not easy to be torn
3 self adhesive tape, security and security open
4 waterproof, sunscreen
Use:

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. |
