Simultaneous systems stretch the film in both directions at the same time. The mechanical systems for simultaneous stretching have limited yield and stretching forces as well as low flexibility due to the limitations of the complex solutions.
This situation led Brückner to develop its unique LISIM® technology (Linear Motor Simultaneous Stretching), using linear motors driving clips without any mechanical connections.
This drive principle allows a new level of freedom when manufacturing high-quality simultaneously stretched film in fast and flexible production.
Since 1998, the LISIM® pilot line and production lines have been successfully in operation, providing ample proof of the excellent film properties and high reliability of this system.
