Polypropylene film is the core material of the capacitor, which is made of polypropylene resin by casting, blow molding or biaxial stretching. Polypropylene film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant. It is currently the most widely used capacitor film.
Polypropylene Film Production Process:
Thick film production: resin is melted and extruded at 170-210 ° C, and flows out from the circular rotating head through the filter to the inner cooling jacket, and is cooled to obtain a thick tube film.
Vertical and horizontal stretching: the tube film is preheated to the stretching temperature by infrared rays, and under the action of compressed air and clamping wheels with different speeds before and after, the tube film is stretched in both vertical and horizontal directions at the same time.
Trimming and winding: After cooling, the cylinder is divided into two layers of membranes, and then rewound after heat treatment.

In terms of product application, Automotive is the largest application, hold a share of 38% in 2023. The main applications of film capacitors in the field of new energy vehicles are: new energy vehicle electric drives, OBCs and charging piles. The drive inverter is one of the most important components in the electric vehicle power system. Power modules, sensors, and film capacitors are the most critical equipment. The growth of new energy vehicles will drive up the demand for film capacitors/raw material films.
Market Drivers:
- Support from national policies: For example, in China, Benefit from China’s emphasis on new energy, the market has grown rapidly. And considering the long-term impact of "peak carbon dioxide emissions" and "carbon neutrality" policies, the business cycle of the capacitor film industry will be extended, and it is expected to show a slow upward trend in the future.
- Downstream market demand: The development and growth of the capacitor film market is driven by many driving factors, especially in the fields of new energy vehicles, electronics, energy storage systems and 5G.
Restraint:
- Market competition intensifies:
The polyester film industry is highly competitive, with continued growth in market capacity and an increasing number of large-scale production companies. As the production scale of polyester film companies continues to expand, market competition in the global polyester film industry has further intensified. In this competitive environment, the gross profit margin of some companies' products may decline.
- High technical barriers in high-end industries:
Among the companies capable of producing BOPP ultra-thin capacitor films, due to factors such as high technical thresholds, large R&D investment, and multiple product functions, there are relatively few companies that can produce ultra-thin films. But on the contrary, it has a strong competitive advantage in market segments.
Trend:
- Improved product performance: mainly reflected in film thickness (ultra-thin), corrosion resistance, high temperature resistance, and high-pressure resistance. And it can meet the mechanical and electrical performance requirements of different application scenarios.
Ultra-thin Film: In the field of new energy vehicles, ultra-thin capacitor films can accommodate more energy storage materials, increase the energy density of batteries or capacitors, increase vehicle cruising range, and meet users' needs for long-distance driving. And ultra-thin films can also reduce capacitor weight and control costs.
High temperature resistance: New energy vehicle batteries will generate heat during operation. The high temperature resistant film can cycle stably in this environment, avoiding performance degradation in high temperature environments and maintaining long-term use. High-temperature resistant film capacitors are the key to ensuring the stable, safe and long-term operation of NEV batteries under complex working conditions and promoting the reliability and popularity of electric vehicles.
- Market size and downstream demand growth: The rapid development of downstream new energy vehicles, photovoltaics, UHV and other fields will further drive demand in the electronic components/electronic component materials industry. For example, the "New Energy Vehicle Industry Development Plan (2021-2035)" issued by the Chinese government proposes that by 2025, China's new energy vehicle sales will account for more than 20% of new automobile sales, and by 2035, new energy vehicle sales will account for more than 20% of new automobile sales. New car sales are mainstream. In the future, the market capacity of PP films for new energy vehicle capacitors is expected to exceed 10 times, and the film thickness is mainly concentrated at 2.0-2.9 microns.
