As the packaging industry increasingly demands intelligent and efficient solutions, the RZFD-450A square bottom paper bag machine with printing inline emerges as the ideal choice for many enterprises. With cutting-edge technology and outstanding performance, it is leading the industry into a new era of smart manufacturing.
From a structural perspective, the unwinding system incorporates advanced automatic tension control to maintain consistent paper tension during the feeding process, preventing wrinkles and breakage. Paired with an Italian-engineered web guiding system, the machine provides rapid and precise deviation correction, significantly reducing alignment time and material waste while ensuring a stable paper supply for subsequent stages.
One of the machine's key highlights is its printing unit, which utilizes environmentally friendly flexographic printing technology. It delivers high-resolution prints with vivid color reproduction, whether for minimalist designs or intricate artwork. This ensures customized packaging solutions that meet diverse customer demands.
The gluing section adopts reliable longitudinal gluing technology that ensures uniform adhesive application across various speeds, resulting in firmly shaped paper bags and enhanced product quality.
During the bag forming, cutting, and traction stages, the integration of German SICK color mark sensors and precision servo motors—combined with a French Schneider touchscreen HMI—allows for seamless control. Operators can easily configure production parameters through the intuitive interface, enabling fast, accurate, and stable bag production at speeds of 30–150 bags per minute. This empowers enterprises to respond swiftly to market demands.
Equipped with fully automated bottom folding and gluing functions, the RZFD-450A ensures durable and aesthetically pleasing bag bottoms. The automatic vertical stacking system organizes finished bags in neat, orderly batches, simplifying packaging and transport while significantly reducing labor costs. With a wide range of bag size options, the machine meets packaging needs across industries such as food, apparel, and gifts. Choosing the RZFD-450A means injecting powerful momentum into your packaging production, staying ahead in a competitive market, and advancing toward sustainable development.
