The RZJD-G450J fully automatic high-speed window flat bottom paper bag machine is an automated production machine that integrates window processing with flat bottom paper bag making. It is specifically optimized for the production requirements of display-type paper bags. The machine integrates paper feeding, window die-cutting, film patching, tube forming, flat bottom forming, and finished product output into a continuous production workflow, ensuring production efficiency while maintaining both appearance and functional performance of paper bags. It is suitable for batch production of food packaging, retail packaging, and display-type paper bags.
The machine is compatible with kraft paper, food-grade white cardboard, greaseproof paper, and various packaging paper materials, and supports production changeover for different paper bag specifications through an automatic control system. The window unit operates synchronously with the bag-making system, ensuring coordination between the window position and the bag body structure. The window area features neat edges and smooth film attachment, helping improve packaging display performance. Consumers can view the product appearance without opening the package, which better meets modern retail market requirements for visible packaging.
During the bag-making process, the machine coordinates paper feeding, cutting, and forming through servo control and precise positioning technology, making the bag body flatter and the flat bottom structure more stable. Whether producing plain paper bags or printed paper bags, the machine maintains good dimensional consistency and appearance integrity, supporting enterprises in achieving standardized production.
The machine adopts a centralized operation design, allowing paper bag specifications, window size, and operating parameters to be adjusted according to production needs, shortening product changeover time and improving production flexibility. Automated production reduces manual involvement, helping improve production efficiency and reduce material waste. The overall machine structure emphasizes stability and maintenance convenience, meeting long-duration continuous production requirements. It is an important machine for window flat bottom paper bag production, balancing display performance, production efficiency, and packaging quality.
