Putailai: Plans to Invest 2.5 Billion Yuan in Base Film Coating Integration Project

On the evening of November 14, Putailai announced that, considering the current favorable market environment and the actual demand for increased capacity from downstream customers, based on the company's existing capacity and technology, to seize market opportunities and meet the incremental demand from downstream customers, the company intends to use its own funds to inject 760 million yuan into its wholly-owned subsidiary, Sichuan Zhuoqin New Material Technology Co., Ltd., for the construction of the Base Film Coating Integration Project (Sub-project 2 of Phase II).

The project has a total investment of 2.5 billion yuan and covers an area of approximately 68,500 square meters. Once completed, it will add an annual production capacity of 20 billion square meters of base film and 30 billion square meters of coating. The construction site is located in the Semiconductor Materials Industry Functional Zone of Tianfu New District, Qionglai City, Chengdu, Sichuan Province.

The announcement states that the purpose and feasibility of the project are to further leverage the company's integrated advantages of "materials + process + equipment," expand the integrated production capacity of base film coating, and position itself as an integrated solution for lithium battery separators. This aims to meet the increasing demand for high-performance, high-consistency, and high-stability coated separators in the power battery and energy storage battery markets.

Puhua Tai Lai stated that benefiting from the integrated development strategy of "materials + processes + equipment," the company's localization process of base film equipment is progressing smoothly. It has basically achieved self-sufficiency in the core equipment for base film production, with single-line production efficiency leading the industry. By the first three quarters of 2025, the company's high-efficiency base film production capacity will be gradually released, with base film sales exceeding 1 billion square meters, achieving a leapfrog growth compared to the same period. As a leading enterprise in the coated separator processing field, the company is at the forefront of the industry in terms of coating technology, product development, quality control, and production efficiency. In the first three quarters of 2025, the company's diaphragm coating processing shipment volume exceeded 7.38 billion square meters, a year-on-year increase of 56.80%.

In terms of downstream operations, to meet the increasing demand from downstream customers for coated separator products, this capacity expansion project is being carried out to further enhance our supply service capabilities for downstream customers. It will provide customers with a "base film + coating" one-stop purchasing solution, and will also improve the company's competitiveness in expanding the supply system to downstream battery enterprises.

In early November, Putailai stated during an institutional investor survey that in terms of coated separator business, the company has achieved a strong breakthrough in the energy storage field while fully meeting the incremental demand from power battery customers. From January to September 2025, the company's coating processing volume and base film sales reached 7.38 billion square meters and 1.048 billion square meters, respectively, representing year-on-year growth of 57% and 235%, with a continuous increase in market share.
