Various Thickness Aluminum Foil

Various properties of Various Thickness Aluminum Foil

1. Mechanical

The mechanical properties of aluminum foil mainly include tensile strength, elongation, crack resistance, etc. The mechanical properties of aluminum foil are mainly determined by thickness.

Generally speaking, aluminum foil is light in weight, has good ductility, is thin in thickness, and has a small mass per unit area. However, it has low strength and is easy to tear. It is easy to break and produce holes when folded, so it is generally not used alone for packaging products. In many cases, it is compounded with other plastic films and papers to overcome its shortcomings.

2. High barrier properties

Aluminum foil has high barrier properties against water, water vapor, light, and fragrance, and is not affected by the environment and temperature. Therefore, it is often used in fragrance-preserving packaging, moisture-proof packaging, etc. to prevent moisture absorption, oxidation, volatilization and deterioration of the packaging contents. It is especially suitable for high-temperature cooking and sterilization packaging of food.
