As demand for eco-friendly packaging continues to rise, the RZFD-450A(IF) Square Bottom Paper Bag Machine with Integrated Printing Unit has become a preferred production solution in the retail, gift, and food sectors. Known for its excellent load-bearing capacity and elegant square-bottom design, this machine adopts a modular construction that ensures ease of maintenance and system expansion while maintaining long-term operational stability. It offers customers a high-performance, reliable solution to capitalize on the growing green packaging market.
In terms of key configurations, the machine integrates several leading international technologies. The user interface features a SCHNEIDER touchscreen from France, offering a clear layout and intuitive control for quick operator training and real-time monitoring. Its core control system is powered by Germany's LENZE motion controller, combined with a fiber-optic bus communication framework, ensuring rapid response and system stability even under high-speed production conditions.
For printed bag positioning, the system uses a LENZE servo motor and SICK photoelectric sensor from Germany, working in tandem to achieve accurate tracking and correction at high speeds—greatly improving product pass rates. The raw material feeding section includes a hydraulic lifting mechanism and supports automatic constant tension unwinding, reducing manual labor and ensuring smooth paper transport. To further optimize line efficiency, the machine is also equipped with an Italian SELECTRA web guiding system, which significantly shortens paper roll alignment time and enhances overall production continuity.
