TLM packaging machines are classic top-loading machines and are known for box erection, filling and closing. The thermoform filling and closing machines use ultrasound for sealing and punching. They are also equipped with a continually running film transport, and therefore enable continuous filling and long gassing times. Ultrasonic technology opens up many new possibilities for optimizing packaging processes. Due to the short sealing times, considerably higher machine outputs are achieved than with ordinary machines while offering a lower energy consumption. Ordinary sealing tools must constantly be maintained at a certain temperature, the ultrasonic process only requires energy very briefly for 200 to 300 milliseconds per cycle. A further advantage is that punching can be carried out at the same time as sealing, and that the punching cuts are not sharp-edged as the tray is not really cut, but is melted out. As a result, the service life of the punching knives is also prolonged.
