|Aluminum foil bag and aluminum plated bag can be distinguished by
the following ways:|
1, watch: because the brightness of aluminum foil is not as bright
as that of aluminized aluminum, so the reflection of aluminum foil
is better than that of aluminized film. The aluminum coated bags
can illuminate the figure, but the extinction film is coated with
aluminum. The aluminized appearance of the extinction film is very
similar to the aluminum foil. Can plug the bag mouth, through the
light to see the inside of the bag, aluminum foil bag inside is not
light, transparent is the aluminum bag.
|Aluminum Foil Envelopes|
Packaging bag made of pure aluminum foil and plastic film. Aluminum
foil surface can be printed graphics, with sunscreen, high
temperature resistance, moisture and moisture, anti-static
function. Widely used in food vacuum packaging, electronic products
anti-static packaging, chemical raw materials packaging, drug
Aluminum Foil Envelopes with metal foil and inherent
characteristics, qualitative light luster, strong reflection
ability, after the plastic film composites as thermal insulation
packaging, good barrier property, impervious to gases and water
vapor, strong adaptability to temperature, high temperature or low
temperature shape stabilized, shading, retention of aroma are
Three layers of Aluminum Foil Envelopes PET/AL/CPE, four layers of
foil bag PET/AL/NY/CPE
Composite equipment will compond the aluminum foil and plastic film
to generate a composite membrane, then the bag making equipment
will sealing sides, after that, the cutting equipment will cut the
sealing film according to customer’s size to finished the bags.
Composite technology, thermal fusion technology, cutting
technology, bag making process
1 barrier air performance is strong, anti oxidation, waterproof and
2 puncture resistant, tear resistant and storng performance.
3 high temperature resistance, low temperature resistance, oil
resistance, and good performance.
4 anti-static, anti electromagnetic interference (the production
process of composite anti-static materials can be anti-static)
The surface resistance value of 10 8~11 Times Square, the thickness
of 8~18 wire, heat sealing temperature of 150 C + 10
Food vacuum packaging, pharmaceutical packaging, electronic
products, anti-static packaging, etc.
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.
