Aluminum-plastic composite film (aluminum-plastic film) can be used to manufacture lithium-ion batteries. my country’s industry is highly concentrated

Aluminum-plastic composite film, referred to as aluminum-plastic film, refers to a composite film material made of aluminum-plastic material as the base material. Compared with other composite films, aluminum-plastic composite films have the advantages of good cold stamping formability, high barrier properties, anti-static, and lightweight. It can be used to manufacture various types of batteries and has applications in the fields of electric vehicles, consumer electronics, and energy storage. Broad application prospects.

​​According to different production processes, structures and properties, aluminum-plastic composite films can be subdivided into two categories: aluminized composite films and aluminum-plastic films. Aluminized composite film adopts a two-layer structure and is widely used in the packaging field; aluminum-plastic film is the mainstream product in the aluminum-plastic composite film market. It adopts a three-layer folding structure of nylon layer, aluminum foil layer and heat sealing layer. It is widely used in chemical industry, agriculture, and batteries. It is widely used in many fields such as medicine and medicine. In 2022, my country’s aluminum plastic film market will reach 6.12 billion yuan, a year-on-year increase of 13.6%. Benefiting from the growth in market demand for aluminum-plastic films, the development speed of my country’s aluminum-plastic composite film industry continues to accelerate.

The preparation methods of aluminum-plastic composite film include thermal method and dry method. Thermal method is also called thermal method. The aluminum-plastic composite film produced has the advantages of good barrier properties and corrosion resistance, but the cutting performance of the finished product is poor. The dry method is the mainstream preparation method of aluminum-plastic composite film. This method has the advantages of good finished product quality, Advantages include low equipment requirements. Compared with overseas developed countries, my country’s aluminum-plastic composite film industry started late and its technological level is relatively backward, resulting in a high dependence on imports for high-end demand. This is the main challenge facing the development of the industry.

According to the “2023-2028 China Aluminum Plastic Composite Film (Aluminum Plastic Film) Industry Market In-depth Research and Development Prospects Forecast Report》shows that aluminum-plastic composite films can be used to manufacture various types of batteries, with lithium-ion batteries as their end products. In recent years, my country’s lithium-ion battery production has continued to grow, benefiting from the increased prosperity of the new energy vehicle industry and the accelerated iteration of electronic products. According to statistics from the Ministry of Industry and Information Technology, my country’s lithium-ion battery production exceeded 400GWh in the first half of 2023, a year-on-year increase of more than 43%. As application demand continues to grow, the development space of my country’s aluminum-plastic composite film industry will further expand.

my country’s aluminum-plastic composite film industry is highly concentrated, with major manufacturers including Foster, Mingguan New Materials, Huanshen New Materials, Daoming Optical, and Selen Technology. Foster focuses on the R&D, production and sales of RO support films and aluminum-plastic composite films. According to Foster’s annual report, the company’s aluminum-plastic composite film sales will reach 6 million square meters in 2022.

Industry analysts said that aluminum-plastic composite film has the advantages of high barrier properties and anti-static properties, and is an important component of lithium-ion batteries. In the future, as downstream demand gradually releases, its industry prosperity will further improve. However, currently, due to factors such as high technical barriers, the market share of high-end aluminum-plastic composite films in my country is relatively low. It is expected that in the future, as local companies continue to exert their efforts, the output and quality of my country’s aluminum-plastic composite films will further increase.
