BOPP capacitor film industry has high entry barriers and optimistic future development prospects

Capacitive film refers to an electrical grade plastic film used as a dielectric material for film capacitors. It has special requirements for electrical properties, such as high dielectric strength, low loss, high temperature resistance, high crystallinity, etc. BOPP capacitor film refers to biaxially stretched polypropylene capacitor film. It is made of polypropylene resin through melt plasticization, extrusion, casting, longitudinal stretching, transverse stretching, slitting and other processes. It has self-healing and insulating properties. With the advantages of high impedance, low dielectric loss, high dielectric strength, long service life, and excellent frequency characteristics, it is widely used in various fields such as new energy vehicles, photovoltaics, wind power generation, electrified railways, electronics, electricity, and household appliances.
From 2018 to 2022, my country’s photovoltaic, wind power, home appliances, and new energy automobile industries are developing well, which promotes the expansion of demand in the downstream capacitor industry for BOPP capacitor films, causing the domestic demand for BOPP capacitor films to continue to grow. Driven by the growth in demand, domestic demand for BOPP capacitor films continues to grow. The production capacity and output of the BOPP capacitor film industry have also increased. According to the “China BOPP Capacitor Film Industry Market In-depth Research and Development Prospects Report 2023-2028” released by the Industrial Research Center in 2022 , China’s BOPP capacitor film industry output is 162,000 tons, and demand is 154,400 tons.
​​ BOPP capacitor film production involves multiple disciplines such as polymer physics, polymer chemistry, special materials science, electrical technology, and thermal conduction technology, and is a technology-intensive industry. At the same time, there are still high equipment barriers in the BOPP capacitor film industry. There are few BOPP capacitor film production line equipment manufacturers in the world. Most of the domestic production line equipment is imported equipment, and the cycle from production line ordering to production is long. Generally speaking, there are barriers to technology, capital, equipment, brand, etc. in the BOPP capacitor film industry, and the industry entry barriers are relatively high.
After a long period of development, companies in my country’s BOPP capacitor film industry have already achieved considerable production scale and R&D strength. There are many companies with strong competitiveness in the industry, such as Hebei Haiwei Electronic New Material Technology Co., Ltd., Zhejiang Da Southeast Co., Ltd., Aerospace Rainbow UAV Co., Ltd., Anhui Tongfeng Electronics Co., Ltd., Nantong Baizheng Electronic New Materials Co., Ltd., etc. These companies have occupied the domestic market by virtue of their technological advantages, scale advantages, and channel advantages. higher market share.
The downstream of BOPP capacitor film industry is film capacitors. In recent years, the country has successively issued a series of policies to support the development of new energy industries such as wind power, photovoltaics, and new energy vehicles and the film capacitor industry they use, which will help further promote the growth of demand for film capacitors and benefit the development of the BOPP film industry. In the future, with the further expansion of the application of film capacitors in emerging fields such as new energy vehicles, wind power, and photovoltaics, coupled with the further development of digital and intelligent construction and the upgrading of consumer electronics, the demand for film capacitors is expected to further grow, thereby driving the BOPP capacitor film industry further expansion of scale.
