This powder packaging machine integrates a direct push screw dosing system, back-seal sealing, a coding device, and a rounded corner cutting mechanism for fully automated powder packaging. The direct push screw system provides precise and consistent metering for fine powders. The back-seal sealing mechanism produces neat and secure bags. The built-in coding device prints dates, batch numbers, or other information directly onto the packaging film during the process. The rounded corner cutting mechanism creates bags with smooth, safe corners, enhancing the finished product's appearance. The machine features a PLC touchscreen control panel for easy adjustment of bag length, speed, and temperature. Transparent safety doors allow operators to monitor the packaging process while ensuring safety.
