In today's fiercely competitive packaging industry, a highly efficient and multifunctional machine is key to helping businesses stand out. The RZFD-450A square bottom paper bag machine with printing inline is precisely such a high-performance solution—built for efficiency and designed to give your enterprise a competitive edge.
Its unwinding section features an automatic glue spray rewinding system and tension control, combined with a photoelectric-eye-based web guiding system. This significantly reduces alignment adjustment time, minimizes material waste, and ensures smooth, stable paper feeding. The printing unit adopts advanced flexographic printing technology, which is eco-friendly and capable of delivering vibrant, long-lasting colors. It enables precise reproduction of intricate designs and crisp text, adding a unique visual appeal to product packaging.
The gluing unit employs a stable longitudinal gluing technique that ensures even adhesive application, regardless of operating speed, resulting in securely formed bags. Bag forming is achieved using automatic templates, paired with a German SICK color mark photoelectric sensor and a French Schneider touchscreen HMI. The user-friendly interface offers clear, intuitive controls, allowing operators to easily adjust settings and monitor production parameters.
Cutting and traction are driven by precision servo motors, ensuring high-speed, stable bag cutting and feeding. With a production speed of 30–180 bags per minute, the RZFD-450A significantly boosts manufacturing efficiency. In addition, the machine integrates fully automatic bottom folding, bottom gluing, and vertical stacking of finished bags—streamlining the entire process from raw material to final product, reducing manual intervention and lowering labor costs.
This machine supports a wide range of bag sizes, with widths from 220–450 mm, lengths from 300–630 mm, and bottom widths from 100–200 mm. It is ideal for meeting the packaging demands of multiple industries, including food, retail, and gifts. Choosing the RZFD-450A square bottom paper bag machine with printing inline means choosing an efficient, intelligent, and eco-friendly packaging solution—ushering in a new era of high-performance production.
