Biaxially stretched polyester film (BOPET film) is a high-end polyester film that accounts for over 90% of polyester film. BOPET film has the characteristics of high transparency, non-toxic and odorless, good moisture resistance, and excellent optical properties, and is widely used in packaging, photovoltaic, optical display, printing, electronics and other fields. In recent years, with China's economic growth, the demand for BOPET film market has been continuously released, and the industry scale has continued to expand. Thanks to the increase in market demand, China's BOPET film production capacity has steadily improved. At present, China has become one of the main global production locations for BOPET films. According to the "Analysis of the Competition Status of China's BOPET Film Industry and Research Report on Enterprise Investment Strategies" released by Market Research Network, in 2020, the production of China's BOPET film industry reached 2.8 million tons, with a market size of nearly 43 billion yuan. It is expected to grow to over 68 billion yuan by 2026.

With the progress of production technology, the BOPET film industry in China has achieved significant improvements in quality, scale, and performance. The domestic market is gradually becoming self-sufficient, and at the same time, the competitiveness of domestic BOPET films in the international market is also constantly increasing. Due to the impact of the COVID-19 pandemic, the operating rate of foreign enterprises is relatively low, while domestic enterprises resume work and production earlier, and BOPET film orders are gradually shifting to China. In this context, China's BOPET film industry has further developed.



From the perspective of enterprise competition pattern, there are a large number of BOPET film production enterprises in China, which can be divided into three tiers as a whole. The first tier includes enterprises such as Shuangxing New Materials, Kanghui Petrochemical, and Jiangsu Sanfangxiang, with an annual production capacity of BOPET film of over 200000 tons. The second tier includes enterprises such as Zhejiang Yongsheng Technology and Keze New Materials, and the third tier includes Dongcai Technology and Guofeng Plastics. The annual production capacity of BOPET film is less than 100000 tons. From the perspective of production capacity distribution, China's BOPET film production capacity is mainly distributed in eastern coastal areas such as Zhejiang, Jiangsu, and Shanghai, with a total production capacity of over 70%.



At present, China's BOPET film industry still faces structural problems of insufficient high-end production capacity and overcapacity in the middle and low end. The high-end BOPET film market is still dominated by international companies such as China 3M, Mitsubishi, South Korea SKC, and Japan Toray. Against the backdrop of market demand upgrading, the structural adjustment of the BOPET film industry will be an inevitable trend. Domestic enterprises should follow the trend of market development, increase the research and production of high-end products, and compete for more market share of high-end BOPET films.



BOPET film has a wide range of applications, and the market demand is constantly growing. With the upgrading of market demand, the development potential of high-end BOPET film is enormous. China is a major global producer of BOPET films, but due to factors such as research and development capabilities and technological level, domestic products are mostly concentrated in the mid to low-end fields. The industrial structure of BOPET film needs further optimization and adjustment.
