As the packaging industry continues to evolve toward greater intelligence and efficiency, the RZFD-550N square bottom paper bag machine with printing inline has emerged as the ideal choice for many businesses. With its advanced technology and outstanding performance, it sets a new benchmark for smart packaging production.
From a structural perspective, the machine is equipped with an automatic glue spray rewinding system and a cutting-edge tension control system, combined with a high-precision Italian web guiding system. This ensures fast and accurate paper alignment correction, significantly reducing adjustment time and raw material waste, while providing a stable and reliable paper feed for downstream processes.
The printing section is one of the machine's core strengths. Utilizing advanced flexographic printing technology, it offers eco-friendly operation with exceptional precision and color fidelity. Whether it's a minimalist layout or intricate graphics, the machine delivers flawless results, meeting the personalized printing needs of diverse clients. The longitudinal glue application system ensures consistent gluing across varying speeds, resulting in strong, neatly formed paper bags and enhanced product quality.
During bag forming, cutting, and traction, German SICK photoelectric sensors and high-precision servo motors work in unison. A French Schneider touchscreen HMI provides an intuitive control interface for easy parameter setup and precise operation. With a production speed of 30–130 bags per minute, the machine empowers businesses to respond quickly to market demands.
Moreover, its fully automatic bottom folding and gluing system guarantees firm and visually appealing bag bottoms. The automatic vertical bag collection table efficiently organizes finished bags, simplifying counting and transport, and significantly reducing labor costs. The machine supports a wide range of bag specifications, making it adaptable to the needs of various industries.
