Analysis of aluminum plastic film

1, what is aluminum film?

Aluminum plastic film is the core packaging material of soft-pack lithium battery. Soft-pack battery has flexible shape design, light weight, small internal resistance, higher than energy advantages, aluminum plastic film is widely used in 3C consumer batteries, home energy storage batteries and two-wheeler battery field, power battery field will be with the head soft-pack battery manufacturers (LG, SKI, Fueng) and other expansion of production and increase significantly.

2, why now this point of attention to aluminum plastic film?

1) Due to the growing demand for power aluminum plastic film and Japan and South Korea aluminum plastic film manufacturers do not expand production between the contradiction, to promote aluminum plastic film to accelerate localization. According to EV tank data, Japanese and South Korean manufacturers account for about 73% of the global aluminum film market share by 2020. Under the global wave of electrification, power battery manufacturers greatly expand production, but overseas aluminum plastic film enterprises are relatively conservative, the overall expansion of production is small, in the process, overseas aluminum plastic film enterprises will gradually switch their production capacity from 3C to power, so in the field of 3C space, is gradually being replaced by domestic aluminum plastic film.

2) Under the trend of lithium battery reduction, domestic aluminum plastic film ushers in new opportunities. Domestic aluminum composite film and imported products have 20%-30% price difference, domestic lithium battery manufacturers based on cost control needs, aluminum plastic film to achieve domestic replacement requirements are increasingly prominent. At present, in the field of mobile electronic end products, the replacement rate of domestication is relatively high, in the field of two-wheelers and home energy storage, domestic aluminum plastic film is also gradually penetrating, and power batteries and other fields, is still a monopoly position occupied by Japanese enterprises.

3, aluminum plastic film market space?

1) The global demand for aluminum plastic film is expected to be about 1 billion flat in 2025, corresponding to the market space of 16 billion yuan, of which the proportion of powered aluminum plastic film is more than 70%. From the stock dimension, 3C aluminum plastic film accounted for 60% of the global demand for aluminum plastic film in 2020, the future of domestic aluminum plastic film will first gradually penetrate from the 3C field;

2) Aluminum film accounts for about 3.8% of the cost of lithium batteries, accounting for 1.1% of the cost of the vehicle. We take GAC Aion S 2021 Plus Technology Edition as an example, the model sells for 1596 million yuan, the unit has 58.8kwh of electricity, the current imported aluminum plastic film single flat price of about 30 yuan, corresponding to the value of the bike about 1760 yuan (without tax), accounting for 1.1% of the vehicle price. If you assume that the battery PACK sells for about $0.80 a singlewh, the aluminum film accounts for 3.8% of the cost of the power battery.

4, aluminum plastic film process and barriers how?

Aluminum plastic film preparation process has two kinds of heat method and dry method, each has its own advantages. The dry method is represented by the Japanese Showa Electrician and the thermal method is represented by the Japanese DNP Greater Japan Printing. Dry method is not high on equipment, with good depth molding performance, good short-circuit performance, good appearance, good cutting performance, higher durability advantages; At present, the two routes are constantly iterating and innovation, for battery manufacturers, they will not limit the route of aluminum plastic film enterprises, just meet a series of technical parameters, some aluminum plastic film enterprises are developing dry heat composite method to make the final product both advantages.

The barrier of aluminum plastic film lies in the accumulation of Know-how experience in equipment, raw materials, technology, etc., and the technical homogeneity of membrane or printing business. At present, most of the aluminum plastic film enterprises in the market’s main business is not aluminum plastic film, but the main business of these enterprises are film or printing business, with aluminum plastic film technology the same source. We believe that companies with a primary technology build-up and a unique understanding of raw materials and equipment will stand out in the aluminum plastic film industry in the future.
