Developed by our engineering team, the RZFD-330 double-layer paper bag machine is guided by the technical principles of “easy operation, convenient maintenance, and strong adaptability.” By optimizing the user experience across multiple dimensions including human–machine interaction, maintenance efficiency, and industry application compatibility, this model is a preferred solution for small and medium-sized packaging enterprises aiming to achieve scaled production of double-layer paper bags.
At the intelligent operation level, the machine is equipped with a Schneider touch-screen interface. Key parameters such as double-layer paper tension, laminating pressure, bag length, and gluing temperature can all be set with visualized precision. The system supports storage and one-button recall of multiple commonly used parameter recipes, eliminating the need for repeated and complex adjustments during order changes. New operators can independently begin production after short-term training. The built-in intelligent fault diagnosis system continuously detects common production issues such as paper misalignment, poor lamination bonding, and temperature abnormalities. Once an abnormal condition is identified, the machine automatically stops and displays a pop-up indicating the specific fault location, while audible and visual alarms promptly alert operators. This significantly reduces troubleshooting time and effectively ensures production continuity and stability.
The machine adopts a user-oriented, easy-maintenance design. The core transmission system is precisely calibrated and optimized, maintaining low noise levels during operation in accordance with relevant industrial noise control standards. This helps create a more comfortable working environment for frontline operators.
In terms of application adaptability, the machine is designed to address practical production needs in daily-use packaging scenarios. It can produce packaging paper bags with moisture-resistant and leak-resistant performance, meeting packaging standards for various daily-use products. Components that come into contact with materials are manufactured from food-grade compliant materials, ensuring packaging safety.
With its efficient double-layer bag-making capability, convenient operation and maintenance experience, and broad adaptability across application scenarios, the RZFD-330 double-layer paper bag machine has been successfully implemented by many small and medium-sized packaging enterprises. It effectively helps users enhance the market competitiveness of their packaging products and better adapt to diversified market demands.
