Bakery packaging is characterized by small bag sizes, multiple styles, and fast order turnover, requiring the machine to maintain bag-making efficiency while also considering workshop space and order changeover rhythm. The RZFD-190 square bottom paper bag machine is designed for the production of square bottom paper bags such as toast bags, bread roll bags, pastry bags, and small snack bags. With a compact machine layout, it integrates roll paper unwinding, constant-tension paper feeding, photoelectric positioning system, creasing, constant-temperature gluing system, square bottom forming, fixed-length cutting, and collection into a continuous process. Once the paper material is loaded, the machine can complete processing according to the preset workflow, reducing manual handling between production stations and making it more suitable for bakery factories and food packaging workshops handling frequent batch orders.
For commonly used materials such as food-grade greaseproof paper, coated paper, and lightweight kraft paper, the machine coordinates paper feeding through synchronized servo control and the photoelectric positioning system. Different paper materials vary in surface friction, flexibility, and thickness, and stable tension control helps reduce web deviation, wrinkling, and fluctuations in crease positions during operation. The gluing and forming mechanisms can adjust the processing conditions according to material characteristics, helping the bag opening, bag body, and square bottom structure maintain a relatively uniform appearance while meeting the practical requirements of bread and pastry packaging for grease resistance, crumb containment, and hygienic processing.
The machine adopts a modular structure, making each functional unit convenient for inspection, cleaning, and maintenance. Protective covers and shutdown alarm functions for material shortage, paper jams, overloads, and other conditions help operators address abnormalities in a timely manner. The touchscreen panel can store production settings for different bag types, allowing the corresponding parameters to be recalled when changing paper materials or specifications and reducing repeated setup and material consumption during trial runs. With its compact footprint and compatibility with small-size paper bags, the machine can support bakery enterprises in expanding packaging capacity, optimizing production scheduling, and maintaining finished product consistency.
