Aluminum foil has the advantages of good barrier, shading, gorgeous appearance, small weight, non-toxic and other packaging materials can not match. Therefore, aluminum foil is widely used in the field of packaging, is the only metal foil in the field of packaging. When using aluminum foil as packaging material, we should make clear the performance of aluminum foil, so as to better reflect the performance of aluminum foil as packaging material.
Aluminum foil is widely used in packaging field and is the only metal foil in packaging field. When using aluminum foil as packaging material, we should make clear the performance of aluminum foil, so as to better reflect the performance of aluminum foil as packaging material. The five performance classifications of aluminum foil are listed in Huayin small series for your reference.

1、 Mechanical properties of mechanical aluminum foil mainly include tensile strength, elongation and crack resistance. The mechanical properties of aluminum foil are mainly determined by the thickness. The national standard GB / t3189-2003 "aluminum and aluminum alloy foil" has made corresponding provisions on the longitudinal mechanical properties of aluminum foil in China.
In general, aluminum foil is light in weight, good in ductility, thin in thickness and small in weight per unit area. However, it is low in strength, easy to tear, easy to break and produce holes when folded, so it is not used alone for packaging products. In many cases, it is compounded with other plastic film and paper to overcome its disadvantages.
2、 High barrier aluminum foil has high barrier to water, steam, light and fragrance, and is not affected by environment and temperature. Therefore, it is often used in fragrance preserving packaging and moisture-proof packaging to prevent moisture absorption, oxidation and volatilization deterioration of packaging contents. It is especially suitable for high temperature cooking and sterilization packaging of food.
3、 The surface of corrosion-resistant aluminum foil naturally forms an oxide film, which can further prevent the continuation of oxidation. Therefore, when the packaging content is highly acidic or alkaline, protective coating or PE coating is often applied on the surface to improve its corrosion resistance.
4、 Heat and low temperature resistance aluminum foil is stable at high and low temperature. It does not swell and shrink when the temperature is - 73 ~ 371 ℃. At the same time, it has good thermal conductivity, and its thermal conductivity can reach 55%. Therefore, it can be used not only for high temperature cooking or other hot processing, but also for frozen packaging.
5、 The light shielding aluminum foil has good light shielding property, its reflection rate can be as high as 95%, at the same time, the appearance is silver white metal luster, through the surface printing decoration can show good packaging decoration effect, so aluminum foil is also a kind of high-grade packaging material.
