Five major properties of Mingtai Aluminum high quality aluminum foil


The mechanical properties of aluminum foil include tensile strength, elongation, crack strength and so on. The mechanical properties of aluminum foil is mainly determined by the thickness of the national standard GB / T3189-2003 "aluminum and aluminum alloy foil," China's aluminum foil longitudinal mechanical properties made the appropriate provisions.

Mingtai Aluminum aluminum foil has a high barrier against water, water vapor, light and fragrance, and is not affected by the environment and temperature. Therefore, it is commonly used in fragrant packaging, moisture-proof packaging and the like to prevent moisture absorption, oxidation and volatilization of packaging contents. Especially suitable for high-temperature cooking food sterilization packaging.

The surface of the aluminum foil naturally forms an oxide film. The formation of an oxide film can further prevent the oxidation from continuing. Therefore, when the content of the package has high acidity or alkalineity, it is often coated with protective coating or PE on the surface to improve Its corrosion resistance.

Aluminum foil at high temperature and low temperature stability, the temperature at -73 ~ 371 ℃ does not expand deformation, at the same time has good thermal conductivity, the thermal conductivity up to 55%. So it can be used for high-temperature cooking or other thermal processing, but also can be used for frozen packaging.

Aluminum foil has good shading, the reflective rate up to 95%, while the appearance of silver-white metallic luster, through the surface printing decoration can show a good packaging and decorating effect, aluminum foil is also a high-end packaging materials.
