The machine is used to make complex-film central sealing bags and 3-side sealing bags. The machine is controlled by computer. The whole production process can be monitored and displayed dynamically on the screen. We apply duo-servo system to realize synchro length determimation. Photo-electric correction, pneumatic tension regulation, converter speed regulation. sealing temperature adjustable. It features high control accuracy, safe and reliable performance easy to operate. It's technology reaches the advanced level of the world.Main performance:Bag types: flat bag: foldedMax. bag making beat: 140 times/minMax. film speed: 40 m/minBag width: 35-350mmFolding depth: 10-80mmBag making accuracy: <=+-1mmTemperature stability: <=30CFilm roller Max. size (diameter * width ): 600*870mmMain structure:2 servo3 set longitudinal, lateral heat sealing blades1 set punching device
