Market Size

As of 2025, the Global polypropylene film for capacitors market is estimated at USD 2,200 million. Forecast models project the market to reach USD 4,000 million by 2034, reflecting a compound annual growth rate of 8.6% over the 2025‑2034 period.

Product Definition

The production of polypropylene film follows a structured process:

• Thick Film Production: Polypropylene resin is melted at temperatures ranging from 170‑210°C. The molten resin is extruded and filtered, forming a thick tube film that is then cooled.
• Vertical and Horizontal Stretching: The tube film is heated with infrared rays and simultaneously stretched in both directions using compressed air and clamping wheels operating at varying speeds.
• Trimming and Winding: After cooling, the cylinder is split into two membrane layers and rewound after heat treatment.
