8006 8021 Aluminium Foil Big Roll

The most common aluminum foil big roll alloys are 8011, 8021, 8006, 8079 aluminum foil. They are widely used in beer labels, cables, pharmaceutical packaging, household foil food packaging, bottle cap materials, heat-sealing foil, etc. Especially after the composite processing of aluminum foil and paper, the packaging performance of the 8 series aluminum foil has been further improved.

8006 aluminum foil is a special container foil, of which the tensile strength is between 123-135. Haomei 8006 aluminum foil jumbo roll can reach water washing grade A. Its surface is clean and free of oil. 8006 aluminum foil is produced by hot rolling process. After stamping, the edge has no wrinkles and has a beautiful appearance. It is widely used in aircraft lunch container in Europe.

8006 aluminum foil is a non-heat-treatable aluminum alloy. The elongation and cup convexity of 8006 aluminum foil are higher than those of 8011. The tensile strength of 8006 container foil is also slightly higher than that of 8011 aluminum foil. Under the same product specifications, the price of 8011 aluminum foil is slightly lower than that of 8006 aluminum foil.

8006 alloy contains Mn element, which is especially beneficial to the corrosion resistance of aluminum foil. When aluminum foil is used in the air conditioner and beer label, 8006 alloy has better mechanical properties than 8011, 8079, and 1235 alloys. The rolling process performance of 8006 alloy is good, and it is not easy to produce edge cracking defects.

8021 aluminum foil has excellent moisture-proof performance, light-shielding and extremely high barrier ability. It is one of the raw materials used in aluminum food packaging industry. 8021 aluminum foil has the characteristics of cleanliness and sanitation. It can be made into integrated packaging materials with many other packaging materials, and the surface printing effect of 8021 aluminum foil is better than other materials.

Its application inf food packaging is inseparable from its good alloy properties. The surface of 8021 aluminum foil is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface. It is a non-toxic packaging material that can be in direct contact with food without any danger to human health.

In addition, 8021 aluminum foil is an opaque packaging material, which is a good packaging material for products that need to avoid sunlight. For example, aluminum foil packaging is commonly used for margarine packaging. In terms of processing, 8021 aluminum foil has good plasticity and can be processed into products of various shapes.

8021 aluminum foil paper has good performance in terms of strength, elongation and compressibility, and is expected to be used as a flexible packaging for lithium-ion batteries. It occupies an important part in the currently hot lithium battery materials. The thickness of aluminum foil is generally between 0.01-0.06 mm.
