Small-size food paper bags are typically characterized by a wide variety of styles and frequent order changeovers, making the coordination between printing and bag making a key factor affecting production lead time. The RZFD-190 paper bag machine with printing inline integrates roll paper unwinding, flexographic printing, constant-tension paper feeding, photoelectric positioning system, servo creasing, constant-temperature gluing system, square bottom forming, cutting, and finished product collection into one continuous production process. This integrated workflow reduces semi-finished product handling and repeated material loading, allowing printed paper to enter the bag-making process directly, making the machine well suited for workshops producing multiple small-size packaging orders.
The machine supports multi-color environmentally friendly water-based ink printing and is compatible with commonly used materials such as food-grade greaseproof paper, kraft paper, and coated paper. It accommodates a wide range of paper weights and finished bag specifications. Typical applications include toast bags, bread takeaway bags, snack packaging bags, and tea beverage takeaway bags. During production, the constant-tension paper feeding system and photoelectric positioning system help maintain stable paper transportation, reducing the impact of web deviation on print registration and bag quality. Servo creasing provides accurate fold positioning, while the constant-temperature gluing system ensures more uniform bottom forming and adhesive bonding.
The RZFD-190 adopts a centralized touchscreen control system capable of storing production parameters for printing, paper feeding, and bag making. When changing paper materials, bag specifications, or printing layouts, operators can quickly recall the corresponding settings, reducing repeated setup time. The machine is also equipped with protective functions for material shortage, paper jams, and printing registration deviations, allowing operators to promptly inspect the paper path and processing conditions. For bakery, snack food, and tea beverage packaging manufacturers, this model combines high-quality graphic presentation with reliable square bottom paper bag forming, providing dependable support for the production scheduling and delivery of small-batch, multi-design printed paper bags.
