The RZFD-190 square bottom paper bag machine with printing inline is developed to meet the continuous production requirements of small- and medium-size square bottom paper bags. By integrating printing and bag-making processes into a single production line, the machine completes printing, paper feeding, tube forming with gluing, bottom folding and bottom gluing, and finished bag collection directly from roll paper. This integrated approach reduces the need for multiple equipment connections and manual material transfer, making the production process more compact and controllable. In practical operation, this configuration helps reduce paper loss during intermediate handling and improves overall production continuity, making it suitable for packaging enterprises to build high-efficiency square bottom paper bag production units.
In terms of coordination between printing and forming, the machine achieves synchronized control between the printing unit and the bag-making process, ensuring stable and consistent ink transfer and graphic presentation. The ink transfer and doctor blade structures operate smoothly during continuous production, delivering clear graphic layers and uniform color performance. Combined with a circulating ink management system, this helps improve consumable utilization efficiency. Coordination between the printing process and bag cutting is achieved through positioning and tracking systems, allowing printed graphics to align accurately with bag forming. This ensures consistent appearance quality while maintaining uniformity of finished bags.
In terms of production adaptability and operation, the machine provides good coverage for small- and medium-size square bottom paper bags and supports printing and bag-making requirements for a variety of commonly used paper materials. The overall machine structure is compact, with a relatively concentrated footprint, making it suitable for installation within existing factory layouts. The operation interface adopts a touch-screen design, with key operating parameters and production status displayed centrally. The adjustment logic is clear and user-friendly, allowing operators with different levels of experience to use the machine effectively. The RZFD-190 square bottom paper bag machine with printing inline provides stable and reliable equipment support for packaging enterprises carrying out standardized and batch production of small- and medium-size square bottom paper bags.
