As the packaging industry accelerates its shift toward higher automation and efficiency, the RZFD-450AF square bottom paper bag machine with flat handle inline sets a new benchmark for intelligent manufacturing. Powered by cutting-edge technology and outstanding performance, it offers a next-generation production experience for modern enterprises.
Structurally, the machine integrates an advanced automatic glue-spray rewinding system and a high-precision tension control unit, working seamlessly with an Italian web guiding system. This configuration enables fast and accurate paper alignment, significantly reducing setup time and raw material waste while ensuring a consistent and reliable paper supply for downstream processes. The printing unit adopts state-of-the-art flexographic technology, delivering eco-friendly output with exceptional print accuracy and vivid color reproduction to meet diverse and personalized branding requirements.
The machine also excels in handle production and bag forming. Flat handles are automatically formed from reel paper and firmly attached with high positioning accuracy. Bag forming, cutting, and traction units operate in synchronized precision—controlled via a Schneider touchscreen HMI from France. This user-friendly interface simplifies operation and allows precise parameter adjustments. With a production speed of 30 to 150 bags per minute, the RZFD-450AF enables manufacturers to respond rapidly to dynamic market demands.
The fully automated bottom folding and gluing unit ensures strong, cleanly formed bag bottoms. Finished bags are then efficiently organized by the vertical automatic collection table, streamlining stacking, counting, and logistics while significantly reducing labor intensity.
With wide-ranging customization capabilities, the RZFD-450AF is ideal for diverse applications across multiple industries. In the food sector, it rapidly produces hygienic, food-grade bags. In retail, it delivers stylish, durable shopping bags. In the gift market, it crafts elegant and distinctive packaging solutions. Choosing the RZFD-450AF means equipping your operations with intelligent automation—unlocking productivity, capturing new market opportunities, and fueling long-term sustainable growth.
