The RZFD-450ATF round and flat handle integrated square bottom paper bag machine is developed under the core concept of “fully integrated process and multi-format adaptability.” It combines both round rope and flat rope handle forming technologies, providing high-precision and high-efficiency packaging solutions for a wide range of industries.
The machine covers the entire production process—from paper roll feeding, square bottom forming, and handle pasting to finished bag output. With a digital control system enabling precise coordination across multiple modules, it significantly reduces manual intervention and greatly improves overall productivity compared with conventional machines. Equipped with an automatic handle switching system, it flexibly adapts to either round or flat rope handles. Through its modular structure, the handle units can be quickly replaced, enabling seamless switching between round and flat handle modes. The gluing temperature and amount are automatically controlled, ensuring firm adhesion, clean appearance, and consistent load-bearing performance suitable for diverse packaging requirements. The square bottom forming section adopts a high-precision servo indentation control system, ensuring minimal dimensional deviation and flat, well-sealed bag bottoms.
In terms of performance, the machine supports the production of various common paper bag sizes and can be rapidly adjusted for different orders by switching parameters. It delivers stable production capacity while effectively reducing paper material waste. Key components such as cutting knives are made from wear-resistant materials, extending the machine’s overall service life.
The equipment provides flexible application solutions tailored to the needs of different industries. In the food sector, it is ideal for producing handled bags for snacks and bakery packaging. In the daily chemical industry, it supports embossed or specialty paper materials to enhance packaging texture. In the cultural and creative sector, customized handle colors enable efficient mass production of personalized gift bags.
With its integrated handle forming and bag making processes, along with stable and intelligent operation, the RZFD-450ATF round and flat handle integrated square bottom paper bag machine has been successfully implemented in numerous packaging enterprises. Its intelligent and efficient production model helps companies reduce labor dependence, improve productivity, and strengthen brand image, bringing new opportunities for innovation and transformation in the packaging industry.
