The RZFD-550N square bottom paper bag machine is developed to meet the requirements of scaled production of square bottom paper bags. Using roll paper as raw material, it integrates processes including paper feeding, side gluing, tube forming, cutting, creasing, and square bottom forming into a unified production line. All processes operate in coordination under a centralized control system, reducing the impact of segmented manual operations on production rhythm and making the bag-making workflow more continuous and stable. This model is suitable for packaging enterprises carrying out continuous production of large-size square bottom paper bags.
In terms of material adaptability and forming control, the machine demonstrates good compatibility with a variety of commonly used packaging paper materials and can cover production requirements for square bottom paper bags in different specifications. During operation, the tension control and web guiding systems continuously monitor and adjust paper feeding conditions, ensuring consistent bag forming dimensions. This helps reduce material loss and improve finished product stability. The operating rhythm and output capacity are well balanced, meeting the requirements of scaled production for continuity and efficiency.
In terms of operation and structural design, the machine is equipped with an intuitive human–machine interface, with main operating parameters displayed centrally. The adjustment process is clear and convenient, allowing operators to become familiar with operation within a relatively short time. The overall machine structure is well organized, with clearly defined component zones, making routine inspection and maintenance relatively straightforward. Key components are selected and assembled with consideration for durability and long-term operation requirements, enabling the machine to maintain stable performance under continuous production conditions. This makes it suitable for standardized and automated square bottom paper bag production in industries such as food, supermarkets, and apparel.
