Although foil aluminum bags material is very thin, as a packaging material, it has the following advantages:

(1) Light weight, which is conducive to reducing transportation costs.
(2) Good isolation and shading properties. It is moisture-proof, airtight and has fragrance-preserving properties, and can prevent moisture absorption, oxidation and volatilization of packaging.
(3) Good heat resistance, stable shape at high temperature and low temperature, and can be used as a container for baking.
(4) Strong protection: make the package less susceptible to damage by bacteria, mold and insects.
(5) Good reflection and gloss of light. It has high reflectivity to heat and light, and its reflectivity reaches 83% to 85%, so it has excellent exhibition and sales effect.
(6) Good mechanical properties, can meet the use of automatic packaging machinery.
(7) The secondary processing moldability and embossing are good.
(8) Good adaptability to printing and compounding. Easy to color, easy to fit with paper, plastic, etc.
(9) Non-toxic, not easy to cause pollution.
Although foil aluminum bags material has the above advantages, aluminum foil is rarely used alone due to its low strength, poor tear resistance, easy cracking when folded, not resistant to acid and alkali media, and cannot be thermally bonded and sealed. The vast majority of foil aluminum bags material is composited with plastic film, paper and other materials, and used in the form of composite materials. This not only maintains the excellent properties of aluminum foil, but also makes up for the deficiencies of aluminum foil in some packaging properties.

Foil aluminum bags material is a new type of packaging material with strong adaptability and wide application range, which can be used as both flexible packaging materials and semi-rigid and rigid packaging materials. It is now widely used in food packaging and has replaced some metal cans.
