8011 aluminum foil manufacturer introduces five aluminum foil properties

Edit:Mingtai Date: 2019-10-29 16:53
Aluminum foil is widely used in the packaging field and is the only metal foil in the packaging field. The 8011 aluminum foil manufacturer reminds you that when using aluminum foil as a packaging material, it is necessary to clarify the performance of the aluminum foil to better reflect the performance of the aluminum foil as a packaging material. The following is a description of the five major properties of aluminum foil.
1, mechanical
The mechanical properties of aluminum foil mainly include tensile strength, elongation, crack resistance and the like. The mechanical properties of aluminum foil are mainly determined by the thickness. The longitudinal mechanical properties of aluminum foil are specified in the national standard "Aluminum and Aluminum Alloy Foil".
8011 aluminum foil manufacturer introduced, aluminum foil is light in weight, good in ductility, thin in thickness and small in mass per unit area. However, the strength is low, it is easy to tear, and it is easy to break when folded, and holes are generated, so it is generally not used for aluminum foil for packaging alone. 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 to water, water vapor, light and fragrance, and is not affected by the environment and temperature. Therefore, it is often used for perfume packaging, moisture-proof packaging, etc., to prevent moisture absorption, oxidation and volatilization of package contents. 8011 aluminum foil manufacturer found that it is especially suitable for high temperature retort sterilization packaging of food.
3, corrosion resistance
The surface of the aluminum foil naturally forms an oxide film, and the formation of the oxide film can further prevent the oxidation from continuing. Therefore, the 8011 aluminum foil manufacturer reminds you that when the package contents have high acidity or alkalinity, the surface is often coated with a protective coating or coating. Cloth PE, etc. to improve its corrosion resistance.
4, heat resistance, low temperature resistance
The high temperature and low temperature state of the aluminum foil is stable, the temperature does not shrink and deform at -73~371 °C, and has good thermal conductivity, and its thermal conductivity can reach 55%. Therefore, it can be used for high temperature cooking or other hot processing, and can also be used for frozen packaging.
5, shading
Aluminum foil has good light-shielding property, its reflectivity can be as high as 95%, and its appearance is silver-white metallic luster. It can show good packaging and decoration effect through surface printing decoration, so aluminum foil is also a high-grade packaging material.
Mingtai Aluminum is the top ten enterprise in China's 8011 aluminum foil manufacturer. It is one of the top 500 enterprises in China. It produces aluminum foil for packaging with excellent performance, smooth surface, no cracks, corrosion spots and traces of nitrate. It is well received by the market. In the future, we will continue to pay close attention to the quality of aluminum foil products, strive to enhance the influence of corporate brands, enhance customer satisfaction, and create more wealth for customers.
