The RZFD-550NTF paper bag machine with twisted and flat handle inline is developed with a focus on “flexible adaptation and multi-format integration.” It incorporates both twisted and flat handle production into a single manufacturing platform, delivering high-quality square bottom paper bag solutions for food packaging, retail shopping bags, cultural and creative gift packaging, and more.
The machine covers the continuous workflow from roll paper unwinding, bag body forming, handle processing, to finished bag cutting. Through a digital control system, the full process is synchronized with smooth coordination between each module, minimizing manual intervention and enabling efficient switching between mass production and multi-variety orders. In practical applications, the handle unit allows fast transitions between twisted and flat handles, with conventional changeovers completed through modular structures that significantly reduce downtime. Combined with a stable rope feeding mechanism and a constant-temperature gluing system, the machine ensures reliable handle bonding strength suitable for everyday shopping bags and food outer packaging.
The bag-forming section adopts dual-servo drive and a photoelectric positioning system for more precise control over bag dimensions and bottom folding. The forming results are neat and tightly sealed, meeting the needs of applications ranging from lightweight food bags to medium-duty carry bags. The machine supports various paper weights and surface-treated paper materials and can be optionally equipped with a flexo printing unit to complete basic printing—such as brand logos and product information—before bag making, fulfilling the visual requirements of e-commerce packaging, branded retail, and food delivery sectors.
The machine features a reinforced structure, with wear-prone parts manufactured from durable materials to extend service life. The touch-screen interface is intuitive and allows presetting of commonly used production parameters, enabling quick transitions during order changeovers. The RZFD-550NTF is especially suitable for scenarios requiring “integrated handle and bag production.” Whether for daily chemical brands seeking refined packaging, food companies focused on efficiency, or retail businesses pursuing improved delivery speed, the machine provides stable performance and flexible capability to enhance packaging quality and production reliability.
