In the fiercely competitive packaging industry, efficiency and quality are the cornerstones of business success. The RZFD-550N square bottom paper bag machine with printing inline—combining advanced technology with superior performance—is driving a new wave of innovation in packaging production.
One of its key highlights is the advanced automated unwinding system. Equipped with high-precision sensors, it continuously monitors the paper roll status and automatically adjusts the unwinding speed, ensuring smooth paper feeding, minimizing material waste, and maintaining uninterrupted production flow.
The integrated printing unit further enhances its capabilities, utilizing state-of-the-art flexographic printing technology for vivid, long-lasting colors and highly accurate registration. It faithfully reproduces a wide range of creative designs on paper bags, boosting product aesthetics and elevating brand image.
During the bag forming process, the machine features German SICK color mark sensors and a French Schneider touchscreen HMI for intuitive, user-friendly operation and accurate parameter settings. The cutting and traction systems are precisely controlled by servo motors, enabling high-speed, stable bag production at up to 30–130 pieces per minute, significantly improving productivity.
Its fully automated bottom folding and gluing functions operate in seamless coordination, ensuring firm and visually appealing bag bottoms. The automatic vertical bag collection platform organizes finished bags neatly, reducing manual labor and enhancing post-production efficiency.
Versatile in application, the RZFD-550N can produce a wide range of paper bag sizes, making it suitable for industries such as food, retail, and gifts. Whether it's for snack packaging, trendy shopping bags, or elegant gift bags, this machine delivers with ease. Choosing the RZFD-550N square bottom paper bag machine with printing inline means opting for a high-efficiency, intelligent, and high-quality packaging solution—ushering your production into a new era.
