|Performance. In addition, the composite membrane is mostly used for
food packaging. In the process of composite membrane processing,
adhesives should be used, and the selection of solvents and bonding
process must meet the corresponding hygienic standard requirements.
The co extrusion film has many characteristics of the composite
membrane, but there is a difference. That is, all the layers of the
co extruding film are extruded together at the same time, so there
will be no other non plastic materials such as aluminum foil and
paper. The combination form of its product materials is relatively
small, and its application scope is also small. However, due to the
combination of the winter layer and the layer by hot melt, no
adhesive is needed, so the hygienic safety of the Food Packaging Co
extrusion film is relatively reliable.|
|Poly bubble mailers|
Poly bubble mailers is actually refers to the bubble envelope,
differing only in the names, in order to avoid the customers all
over the world can not find the ideal products because of different
names, so many of our same products used different names, although
we are still missing a lot, but we are working on it, and
constantly improve the name to cover.
Liner Poly bubble mailers by the inner padded and film on the
surface lined with low density polyethylene, outer membrane for
pet, but also the use of pure aluminum, using pure aluminum with
higher fire prevention, anti radiation effect, for transport in
extreme environments, such as areas near the equator,
high-temperature over 40 Celsius degree, nuclear radiation near the
source area. The fire resistance of coated PET film than the metal
film, but also can heat preservation, heat insulation, packaging
and storage some frozen food can prolong the time to dissolve.
Thick buffer layer can effectively protects the product in express
transit by the impact, aluminum foil liner envelope specific anti
radiation, thermal insulation function, , under the shadow of the
crisis at Chernobyl and Japan's Fukushima nuclear radiation,
nuclear pollution is increasingly being attention. PET film express
liner bag, for love outdoor activities of people is a good choice,
you can put the frozen beer, beverage, ice cream into the bag, can
prolong the time of being cold.

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.
