Aluminum foil alloy 8011
Aluminum foil alloy 8011 has many uses, from yogurt covering foil, medical packaging foil, household foil, food container foil, car heat insulation film to tape aluminum foil. What are the characteristics of 8011 aluminum alloy foil?
1. Aluminum alloy foil 8011- mechanical capability
Aluminum alloy foil has light weight, good ductility, thin thickness and low mass per unit area. However, the strength is low, it is easy to tear, and it is easy to break when folded, resulting in holes, so it is usually not used alone for packaging products. In many cases, it can be mixed with other plastic films and paper to overcome its shortcomings.
2. Aluminum alloy foil 8011- high barrier performance
Aluminum foil alloy 8011 has high barrier properties to water, water vapor, light and aroma, and is not affected by environment and temperature. Therefore, it is usually used in perfume packaging, moisture-proof packaging, etc., to prevent moisture absorption, oxidation and volatilization of the package contents. It is especially suitable for high-temperature cooking and sterilization packaging of food.
3. Aluminum alloy foil 8011- corrosion resistance
An oxide film is naturally formed on the surface of the Aluminum Foil 8011, and the formation of the oxide film can further prevent the continuation of oxidation. Therefore, when the contents of the package have high acidity or alkalinity, a protective coating or PE coating is usually applied to the surface to improve its corrosion resistance.
4. Aluminum alloy foil 8011- heat resistance and low temperature resistance
The Aluminum Alloy Foil is stable at high and low temperatures, does not shrink or deform at -73~371°C, has good thermal conductivity, and the thermal conductivity can reach 55%. Therefore, it can be used for high-temperature cooking or other heat treatment, and can also be used for frozen packaging.
5. Aluminum alloy foil 8011- shading
Aluminum foil alloy 8011 has good shading properties, the reflectivity can be as high as 95%, and the appearance is silver-white metallic luster. Surface printing decoration can show good packaging and decorative effects, so aluminum foil is also a high-end packaging material.
