In the packaging industry, high-efficiency and precision manufacturing equipment is key to enhancing competitiveness. The RZFD-550 square bottom paper bag machine with inline printing stands out with its exceptional performance and unique design, making it an ideal choice for many packaging businesses.
Integrated design streamlines production
Its greatest highlight is the innovative integration of printing and bag-making. Using advanced flexographic printing technology, the printing unit is seamlessly incorporated into the bag-making process, completing both printing and bag forming in a single operation. This drastically shortens production cycles. In traditional processes, printing, rewinding, and then bag-making involved multiple steps, increasing complexity and cost. The RZFD-550 eliminates these intermediate stages, reducing labor costs and equipment investment. It supports multi-color printing with eco-friendly water-based ink, and is fully compatible with common kraft paper and other roll materials (80–150g/m²), meeting diverse packaging needs.
High productivity with precision quality
A dual-roll paper design ensures seamless material switching, enabling continuous printing and minimizing downtime for roll changes, significantly boosting productivity. Printing precision reaches ±0.15mm, with a color mark sensor precisely controlling registration for consistent print quality across every bag.
Wide application range
Whether for food takeaway bags, supermarket shopping bags, or medical packaging bags in high-volume production, the RZFD-550 delivers outstanding results, helping businesses produce high-quality paper bags efficiently.
