The golden age of aluminum pouch film

Aluminum pouch film, a seemingly ordinary composite film material, is quietly emerging as a pivotal force driving the new energy revolution. As the core material for lithium battery soft packaging, it plays an irreplaceable role in the fields of new energy vehicles, consumer electronics, and energy storage, thanks to its lightweight, high safety, and environmental friendliness.

1. Aluminum pouch film: The "invisible armor" of the new energy industry

Aluminum pouch film is composed of a nylon layer, an aluminum foil layer, and a polymer adhesive layer, presenting extremely high technical barriers. In pouch lithium-ion batteries, aluminum pouch film not only accounts for 15%-20% of the cell cost but also determines the level of thinness and safety performance of the battery. By 2026, with global new energy vehicle sales exceeding 30 million units, the demand for aluminum-plastic film is expected to surge. In 2025, the consumption of aluminum-plastic film for pouch power batteries reached 800 million square meters, and it is projected to reach 950 million square meters in 2026. Guangdong Btree New Energy Material Co., Ltd annual production capacity for aluminum pouch film stands at 150 million square meters, with its pure thermal and dry process aluminum-plastic films leading the industry. The core advantages of aluminum pouch film lie in:

Lightweight Revolution: Compared to steel-cased batteries, aluminum-plastic film packaging reduces battery weight by 30%, enhancing the endurance of new energy vehicles;

Safety barrier: The aluminum foil layer blocks oxygen and moisture, while the polymer layer resists corrosion from the electrolyte, significantly reducing the risk of battery fire;

Environmental pioneer: Recyclable design reduces resource waste and aligns with the global trend of carbon neutrality.

II. Future Outlook: Technological Iteration and Globalization Layout

1. Technological trends

Material innovation: Develop high-temperature resistant polymers to ensure the aluminum pouch film maintains its sealing property even in an environment at 150℃;

Intelligent production: Introducing an AI quality inspection system to reduce the defective rate of products from 5% to 0.1%.

2. Market forecast

From 2026 to 2030: The global aluminum-plastic film market is expected to experience a compound growth rate of 18%, with China's share increasing to 65%;

Application expansion: From lithium batteries to solid-state battery packaging, the demand for aluminum-plastic film for solid-state batteries is expected to increase by 300% by 2026.
