Recently, TSF Company has successfully developed a high value-added 2.2 µ m ultra-thin BOPET capacitor film, which is another breakthrough in the field of ultra-thin films after the company successfully developed a 2.4 µ m BOPET film in 2011.

Due to the collaborative efforts of the management team, technical team, and production team of TSF Company, and sufficient preparation work, the progress of the 2.2 µ m ultra-thin polyester film technology research and development was smooth. On the day of research and development, it showed a good state of continuous production for 9 hours and continuous winding of 120000 meters without breaking the film. The finished product was successfully cut and tested, and all performance indicators met the product inspection standards.
