Production Lines for
Battery Separator Film
Batteries power many everyday applications, including consumer electronics, household appliances, and electric vehicles. Separator films are crucial to battery production because they influence safety and energy density.
BOPE (mostly ultra-high molecular weight polyethylene) is the most commonly used material. As the global demand for electric vehicles (EVs) and renewable energy increases, so will the demand for batteries and separator films.
Brückner’s lines for battery separator films with 8.7 m usable film width are the largest of their kind in the world, with an annual output of up to 500 million m² and with consistent film quality.
