The RZJD-G350J flat bottom paper bag machine is developed to meet the scaled production requirements of medium- and large-size flat bottom paper bags. Using roll paper as raw material, the machine integrates processes including unwinding, hole punching, gluing, tube forming, fixed-length cutting, and flat bottom forming into a unified production line. All production units operate in coordination under a centralized control system, reducing intermediate manual handling steps required in traditional production and making the overall bag-making workflow more continuous and stable. It is suitable for packaging enterprises carrying out continuous production of medium- and large-size flat 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 flat bottom paper bags in different specifications. Bag structures can also be adjusted according to actual production arrangements. During operation, the unwinding, paper feeding, and web guiding systems continuously monitor and regulate paper transport conditions, ensuring stable paper movement. This helps reduce bag shape variation caused by paper misalignment and minimizes material loss during production.
In terms of operation and structural design, the machine adopts centralized control combined with a touch-screen human–machine interface, with key operating parameters displayed centrally. Adjustment of bag specifications is relatively simplified, helping shorten production preparation time. Paper roll loading and unloading are assisted by a lifting structure, improving material changeover efficiency. The overall machine adopts a modular structural layout, with independent maintenance areas for each functional unit, making routine inspection and maintenance more convenient. Key components are designed with consideration for durability and long-term operation requirements, allowing the machine to maintain stable performance under continuous industrial production conditions. This makes the RZJD-G350J flat bottom paper bag machine suitable as a core piece of equipment for the production of medium- and large-size flat bottom paper bags.
