Although aluminum alloy 8011 and 8079 aluminum foil are the same aluminum alloy, the performance of 8079 alloy and 8011 alloy is different. Since 8079 alloy contains more iron and silicon, it has higher strength and good compression performance, as well as good ductility and corrosion resistance. In contrast, the strength and ductility of 8011 alloy are slightly inferior to those of 8079 alloy, but its price is relatively low.
Medical aluminum-plastic caps are mainly made of aluminum alloy (8011H16 aluminum) and plastic materials (polypropylene PP), which are processed into medical bottle caps through special processes. As medical bottle caps, aluminum-plastic caps have various specifications and are easy to open. They are widely used in medicine. In the sealing of bottled liquids such as antibiotics, injections, oral liquids, and infusions, aluminum-plastic composite bottle caps also play their unique advantages.
Sealing aluminum foil is mainly composed of aluminum foil and substrate. The aluminum foil material is mainly 8011 aluminum foil. The substrate is the supporting layer of the aluminum foil sealing film, usually made of plastic film or paper.
As the main material of the sealing film, 8011 aluminum foil has good thermal conductivity and thermal insulation, and can effectively block the influence of external temperature and humidity on the product. At the same time, 8011 aluminum foil also has high strength and corrosion resistance, which can protect the product from damage by external physical and chemical factors.
8011 aluminum foil is the main material for PP/ROPP bottle caps. It has good deep drawing performance and low ear-making rate; it has a certain strength after hardening, which is more in line with the requirements of bottle caps.
The process of using 8011 aluminum foil for bottle caps is divided into casting and hot rolling. 8011-H18 aluminum bottle cap foil is mainly used for stamping shallow caps, which can be cast and rolled. 8011-H16 aluminum bottle cap foil is hot-rolled, mainly used for aluminum anti-theft bottle caps.
8079 aluminum foil roll is a kind of aluminum foil with high strength, good elongation and compressibility. 8079 aluminum foil is not only moisture-proof, airtight, light-shielding, abrasion-resistant, fragrance-preserving, non-toxic and tasteless, but also because of its elegant silver-white luster, it is easy to process beautiful patterns and patterns of various colors, so it is more likely to be favored by people. 8079 aluminum foil jumo roll is widely used in food packaging, pharmaceutical packaging, battery soft packaging and other fields.
