Shanghai Metal Corporation is a manufacturer and supplier of 8021 Aluminum composite film.
AA8021 alloy is an aluminum foil material widely used in aluminum-plastic film for flexible pack lithium-ion batteries. It is valued for its excellent deep-draw performance, electrolyte corrosion resistance and heat seal strength. The structure of flexible pack lithium-ion batteries usually includes an aluminum composite film package, in which AA8021 aluminum alloy foil is the core material of the aluminum composite film. Aluminum composite films are made of a multi-layer composite of materials, including an outer barrier layer (usually consisting of nylon or PET), a permeation barrier layer (usually consisting of aluminum foil), and a heat sealing layer (usually consisting of cast polypropylene modified). AA8021 aluminum foil has good barrier properties, which can prevent harmful substances such as moisture and oxygen from intruding into the interior of the battery, protecting the safety and stability of the battery. In addition, it has good cold press molding, puncture resistance, electrolyte stability, high temperature resistance and insulation. With the rapid development of new energy industry, the market demand for AA8021 aluminum foil continues to grow significantly. It is widely used in digital products, cell phones, laptops, Bluetooth headsets, electronic cigarettes and other electronic markets, and its market share and proportion are expected to expand further.
