Our RZFD-330 square bottom paper bag manufacturing equipment is designed with the core concept of “high-efficiency integration and stable output,” providing a highly consolidated forming process for square bottom paper bags. It is suitable for multiple application scenarios including food packaging, daily chemical products, retail, and cultural and creative gift packaging, offering enterprises an intelligent and standardized production solution.
The equipment enables a fully automatic production process covering unwinding of roll paper, creasing and shaping, tube folding, bottom forming, and final bag cutting. With multi-module coordinated operation, it effectively reduces manual involvement and delivers significantly higher production efficiency compared with traditional segmented processes. In terms of performance, the equipment is equipped with a servo paper feeding system and a photoelectric positioning system, ensuring high dimensional stability even under high-speed operation. Combined with a constant-temperature gluing system, it automatically adjusts process parameters according to different paper materials, resulting in a flat and secure bottom seal. Whether kraft paper, white card paper, or offset kraft paper is used, the final bags achieve reliable bonding strength and excellent structural rigidity.
The equipment adopts a modular configuration capable of covering a wide range of commonly used medium-size paper bag specifications. Process switching is convenient, allowing quick parameter adjustments between adjacent orders and supporting flexible production models with multiple batch sizes and specifications. Key components are manufactured with high wear-resistant materials to reduce the frequency of consumable replacement. The machine operates with low noise and energy consumption, meeting the production environment requirements of most small and medium-sized factories. For food-related applications, components that come into contact with materials use food-grade materials to meet hygiene standards, and the system is compatible with biodegradable and other eco-friendly paper materials, supporting the trend toward green manufacturing.
With its stable process performance, flexible specification adaptability, and favorable operating cost control, the RZFD-330 square bottom paper bag manufacturing equipment has become an important asset for various packaging enterprises seeking to increase production capacity and optimize product structures, helping customers achieve higher efficiency and better delivery performance in a competitive market.
