All DORNIER machines have two features in common: exceptional quality and reliability. Optically highly pure film is produced worldwide on DORNIER lines and can be found in flat screens or smart phones on which Netflix and Amazon are streamed. Battery separator film is also produced on DORNIER film stretching lines. It separates cathode and anode in batteries from photovoltaic systems, electric car batteries and smartphone batteries. Another application is flexible packaging. Food and liquids are packaged or filled precisely and resealed according to their shape and volume. This significantly reduces the amount of film used, and protects the food providing freshness of the product.
