As a key material in soft pack lithium batteries, aluminum laminated film (also known as ALF) is widely used in 3C consumer batteries, energy storage batteries, power batteries, and solid-state battery. It has the advantages of weight reduction, material reduction, diverse shapes, and non-explosion resistance.ALF is the flexible packaging film of lithium ion battery, and it is also the most critical and technically difficult material in soft packaging lithium battery. FIRST aluminum-plastic film insists on independent research, and its independent formula is designed in core raw materials such as "PP film, anti-corrosion layer, outer layer adhesive, inner layer adhesive". It has more than 30 technology patents. FIRST has well-developed aluminum-plastic film design and development technical capabilities, has developed electrolytic corrosion resistance, black, ultra-thin and other series of aluminum plastic film, to meet the needs of different customer application scenarios, and constantly develop new products, improve quality. The aluminum-plastic film products produced have been highly recognized by customers, with cumulative shipments exceeding 50 million square meters.
