1. polyethylene is white waxy semitransparent material, soft and
tough, lighter than water, non-toxic, with superior dielectric
2. easy to burn and continue to burn after the fire. The
permeability rate is low and the permeability of organic vapour is
The transparency of 3. polyethylene decreased with the
crystallinity, and the transparency increased with the increase of
The melting point of 4. HDPE is 132-135 C, the melting point of low
density polyethylene is lower (112 degrees C) and the range is
5. at normal temperature is insoluble in any known solvent, and
more than 70 C can be dissolved in toluene, amyl acetate,
trichloroethylene and other solvents.
|Metallic bubble mailers|
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.
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.
The 1 layer is made of pure low density polyethylene film.
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.
The blow molding process, composite process, bag making process
Thickness of 11 wire size can be customized

1. has good mechanical properties, impact strength is 3~5 times of
other films, good folding resistance.
2. oil resistant, fat resistant, acid tolerant, dilute alkali,
resistant to most solvents.
3. with high and low temperature performance, can be used for a
long time at 120 degrees Celsius temperature range, short-term use
of resistant to high temperature of 150 DEG C, -70 resistant to low
temperature, and high and low temperature effects on the mechanical
properties is very small.
The permeability of 4. gas and water vapor is low, and it has
excellent performances of gas resistance, water, oil and odor.
5. high transparency, can block ultraviolet light, good gloss.
6. non-toxic, tasteless, sanitary, safe, and can be used directly
for food packaging.
