Overview of the Development of China's PVA Film Industry
1. Industry Overview
PVA film is a green, environmentally friendly, functional material made from polyvinyl alcohol (PVA) with modifiers and other additives, processed through a specialized process. It features excellent density, high crystallinity, and strong adhesion. The film produced is flexible, smooth, resists oil and solvents, resists scrapes, and blocks gas well. Furthermore, PVA film is biodegradable by bacteria and enzymes, making it a biodegradable polymer material with good environmental compatibility and pollution-free properties.
2. Industry Development History
The development of China's PVA film industry has primarily progressed through five phases. The early exploration phase, from the 1950s to the 1970s, saw the initial application of optical PVA film in areas such as projectors and televisions in the 1950s. However, the overall scale of application was small, and the technology was in its early stages of development. During this period, China's chemical industry had a relatively weak foundation, with PVA film production technology primarily dependent on imports. Domestic research and application of this technology was in its infancy.
From the 1980s to the 1990s, China experienced a period of rapid development. With the rise of liquid crystal display technology in the 1980s, optical PVA film gained widespread application, leading to rapid growth in market demand. China began introducing advanced foreign technology and equipment, attempting to domesticate PVA film production. While some companies ventured into this field, the overall technological level still lagged significantly behind that of foreign countries.
From the 1990s to the early 21st century, China experienced a period of steady growth. In the early 21st century, the optical PVA film industry gradually matured, with continuous technological advancements, significant improvements in product performance, and a further expansion of its application areas. Through technological accumulation and independent innovation, some domestic companies gradually mastered the core production technology for PVA film, continuously improving product quality and production scale, and began to capture a significant share of the domestic market.
From the early 21st century to 2020, China experienced a period of diversified development. In recent years, the application areas of optical PVA film have continued to expand. Beyond traditional display applications, it has also been widely used in mobile phone screens, e-book readers, touch screens, polarizers, and other applications, resulting in continued market demand. Domestic companies are increasing their R&D investment and continuously exploring new production processes and material formulations, driving the development of PVA film products towards high performance, high quality, and customization.
During the rapid growth period since 2020, with the rapid advancement of emerging technologies such as flexible displays, photovoltaic cells, and fuel cells, the application of PVA film in these fields has continued to expand, driving the industry towards high-end, intelligent, and green development. The Chinese government has introduced a series of policies to support the development of the new materials industry, including R&D investment and tax incentives, providing strong support for technological innovation and industrial upgrading in the PVA film industry.
3. Industry Status
In 2023, the market size of China's PVA film industry is expected to reach 2.22 billion yuan, an increase of 18.09% year-on-year. The sales figure is the highest in five years, showing that environmentally friendly materials are doing well, even though the traditional plastic film market is slow. Because of good policies and tech improvements, more areas are using PVA film, like electronics, IT, energy, and health. In the electronics and information technology sector, with the development of technologies such as 5G and the Internet of Things, demand for high-performance, thin, and transparent PVA film is increasing. In the new energy sector, PVA film, as a lithium battery separator material, can improve battery safety, energy density, and cycle life. Furthermore, with growing environmental awareness, PVA film's application in biodegradable packaging, biomedicine, and other fields is also increasing. This diversified market demand provides broad growth opportunities for the PVA film industry, driving the industry's transition from a "substitute" for traditional plastic films to a "mainstream material" across various fields.
