Takeaway paper bags need to accommodate combinations of multiple meals, beverages, and bakery products, while bag dimensions, bottom structure, and bonding condition can all affect performance during delivery. The RZFD-550NT paper bag machine with twisted handle inline is designed for wide-format processing requirements in food service packaging and can produce square bottom takeaway bags, handled food service bags, and fast food bags in different specifications. The machine continuously integrates automatic unwinding, constant-tension paper feeding, photoelectric positioning system, servo creasing, constant-temperature gluing system, square bottom forming, fixed-length cutting, and collection, reducing manual finishing after bag forming and facilitating the organization of batch orders.
For commonly used materials such as greaseproof paper, coated paper, and kraft paper for food service packaging, the machine uses synchronized servo control and the photoelectric positioning system to coordinate the paper feeding process. Tension can be adjusted according to paper thickness and surface characteristics, helping reduce deviation, wrinkling, and stretching of wide-format paper materials during operation while keeping the crease lines of the bag body coordinated with the square bottom position. The constant-temperature gluing system can adjust the adhesive amount and temperature according to the production rhythm, improving the bonding of the bag sides and bag bottom to meet food service packaging requirements for load carrying, grease resistance, and reduced liquid leakage.
The touchscreen control system can store multiple sets of production settings, allowing the corresponding parameters to be recalled when changing bag types or paper materials and reducing repeated setup time. Protective shutdown functions for material shortage, paper jams, and operating deviations allow operators to inspect the paper path and processing conditions in a timely manner and prevent abnormal materials from continuing into subsequent processing stations. For packaging enterprises handling multi-specification takeaway paper bag orders, the machine provides effective coordination between material compatibility, changeover management, and finished bag consistency, supporting the continuous production of square bottom paper bags for food service packaging.
