As the global new energy and display industries continue to shift toward Asia, the competitive landscape of polymer functional films is also changing. Lithium battery separators, polarizers, BOPA films and BOPP films are becoming increasingly important materials across electric vehicles, energy storage, displays and flexible packaging.
China has become one of the world’s most important production bases for these materials. At the same time, the industry is moving from capacity expansion toward higher performance, more specialized applications and global supply-chain cooperation.
Polymer functional films are essential materials in several strategic industries. Lithium battery separators influence battery safety and service life, polarizers are critical to display performance, while biaxially oriented films such as BOPA and BOPP support a wide range of packaging and industrial applications.
According to the original industry analysis, China accounted for approximately 80% of global lithium battery separator shipments in 2025. More than 70% of global display panels were also produced in China, reflecting the continued concentration of downstream manufacturing and material demand in Asia.
This shift is creating new opportunities for Chinese functional film manufacturers to serve both domestic and international customers.
For different application requirements, FSPG offers several major functional film categories, including:
The rapid development of electric vehicles and energy storage continues to increase demand for lithium battery materials.
In 2025, China’s lithium battery separator shipments reached 32.85 billion square meters, with wet-process separators accounting for 80.7% of total domestic shipments. The market is also moving toward thinner separators, higher mechanical strength and more advanced coating technologies.
For battery manufacturers, separator performance is closely related to safety, ion transport and battery consistency. As battery energy density increases, requirements for thickness uniformity, puncture resistance, thermal stability and coating performance are becoming more demanding.
FSPG’s Lithium Battery Separator solutions are designed for applications such as power batteries, energy storage batteries and consumer lithium-ion batteries, supporting the growing demand for reliable separator materials.
The global polarizer market is undergoing a similar transformation.
Historically, the high-end polarizer supply chain was dominated by Japanese and Korean manufacturers. In recent years, however, Chinese companies have rapidly expanded production capacity through investment, acquisitions and technological development.
According to industry data cited in the original article, Chinese manufacturers accounted for approximately 65% of global polarizer production capacity in 2024, with this share expected to approach 80% by 2027.
At the same time, market demand is becoming more diversified. In addition to traditional LCD applications, automotive displays, industrial control systems, smart home devices and wearable electronics are creating new requirements for optical performance and durability.
FSPG’s Polarizer products can support a variety of display and optical applications, helping customers meet different requirements for polarization, transmittance and environmental stability.
Biaxially oriented films represent another important part of the functional film industry.
BOPA film is known for its mechanical strength, puncture resistance and flexibility, making it suitable for demanding flexible packaging applications. It is commonly used in food packaging, vacuum packaging, multilayer laminates and other structures that require reliable mechanical performance.
FSPG provides BOPA Film for different packaging and converting requirements.
BOPP film, on the other hand, is widely used because of its clarity, moisture resistance, stiffness and processing efficiency. It is commonly found in food packaging, labels, printed packaging and lamination applications.
FSPG’s BOPP Film portfolio supports a broad range of packaging and industrial applications.
As competition increases, customers are no longer evaluating these films only by price and thickness. Printability, surface treatment, dimensional stability, optical properties and converting performance are becoming increasingly important purchasing factors.
The restructuring of the functional film industry is closely related to the rapid development of downstream markets.
According to the source article, global new energy vehicle sales reached approximately 23.54 million units in 2025, while global energy storage battery shipments reached 651.5 GWh. These trends continue to support demand for lithium battery separators and related functional materials.
Meanwhile, the growth of automotive displays, smart devices and industrial displays is supporting demand for polarizers, while food packaging and high-performance flexible packaging continue to create stable demand for BOPA and BOPP films.
For Chinese manufacturers, overseas expansion is also changing from simple product export toward deeper participation in global supply chains. Customers increasingly value stable supply, technical support, product consistency and compliance in addition to competitive pricing.
Founded in 1988, FSPG has developed a diversified functional film portfolio covering lithium battery separators, optical films, biaxially oriented films and other polymer materials. The company’s product structure corresponds closely with several growing global industries, including new energy, displays and flexible packaging.
As the global functional film market continues to evolve, competition will increasingly focus on product performance, application development, stable quality and international service capabilities.
With Lithium Battery Separators, Polarizers, BOPA Film and BOPP Film, FSPG is positioned to provide functional film solutions for customers across multiple global markets.
