1. Aluminum Foil Bag Features and Selection Standard
AL (aluminum foil) is one of them, which is usually used as a middle layer. These materials
are composited into composite film upon request by glue!
Common structure of aluminum foil bags:
PET / PA / PE or CPP/ PET / AL / CPP PA / AL / CPP PET/PA0 / AL / CPP. Basic
characteristics: PE is suitable for low temperature use; CPP is suitable for high temperature
cooking. PA can increase physical strength, puncture resistance; AL aluminum foil is used in
order to increase the barrier properties, PET generally is used as an intermediate layer, to
increase mechanical strength, stiff. Then, according to the needs, combinations, various
properties, there are transparent, in order to increase the barrier properties [oxygen barrier
wet resistance, we can use water resistant PVA high barrier coating.
Features:
1. Strong air barrier performance, oxidation resistant, water-proof, moisture-proof
2. Strong mechanical properties, high anti-blasting performance, strong anti-puncture and
tear resistance
3. High temperature resistant (121), low temperature resistant (-50), oil resistance, excellent
aroma retention performance
4. Non-toxic and tasteless, in line with the food, pharmaceutical packaging hygiene standards
5. Good heat-sealing properties, softness, and good barrier properties
6. Aluminum foil bag has metallic luster, which has a higher reflective ability to heat and light,
and aluminum foil bag printing color is more beautiful and bright.
7. Aluminum foil bags have good isolation performance, strong protection performance,
which have impervious to gases and water vapor characteristics, so they can effectively
prevent moisture absorption and gasification of items in the packaging, less susceptible to
bacteria and insects, good shape stability, not subject to changes in humidity impact.
8. Use shield or elution to part aluminize, you can get any pattern and any transparent
window, so that the customer can see the contents in the packaging, which is a significant
advance in the technology of production of aluminum foil bags, but also a notable feature of
aluminum foil bags.
Environmental standards for aluminum foil bag
Aluminum foil bag usually refers to aluminum-plastic composite vacuum bag, such aluminum
foil bag product is suitable for moisture-proof, keeping out of the sun, vacuum packaging of
large-scale precision machinery and equipment, chemical raw materials, pharmaceutical
intermediates. It mostly uses a four-layer structure, which has good impermeable, oxygen

2. barrier function. Unrestricted and can be customized with different specifications, style
aluminum bags food packaging, which can be made into flat pockets, three-dimensional
bags, organ bags and other styles. Aluminum foil bag products should be subject to the GB
and ASTM standard testing, the products comply with the requirements of environmental
protection (third-party test report available); aluminum foil bag products comply with the most
stringent environmental standards for packaging materials in the European Union and North
America.
