Guangdong Btree New Energy Material Co., Ltd has mastered the core technology of aluminum foil passivation

On June 24, 2025, Guangdong Btree New Energy Material Co., Ltd achieved industrial application of its independently developed patent for "aluminum foil passivation processing method and aluminum-plastic film preparation method" (CN116180061B), which has improved the electrolyte resistance of aluminum-plastic films by 30%. This technology addresses the industry challenge of bonding strength between aluminum foil layers and polymer materials by modifying the silane composite passivation fluid formula, enabling the puncture strength of aluminum-plastic films to reach an internationally leading level.

Dual process parallelism

The company's Pingtan base utilizes ten-million-yuan-level thermal equipment imported from Japan, achieving a monthly production capacity of 4 million square meters, while retaining the dry production line. Its thermal products exhibit a heat seal strength of 45N/15mm.

Material self-reliance

Through self-research on CPP film and modified polypropylene adhesive formula, the localization rate of key raw materials has exceeded 80%.

Upgrading environmental compliance

The Huiyang expansion project, approved in September 2024, adopts a low VOCs coating process, reducing unit energy consumption by 15% and complying with the EU REACH regulation.

market performance

The market share of domestically produced aluminum-plastic films has increased from 7% to 15%, with the company's contribution rate exceeding 40%.
