The RZJD-G350J flat bottom paper bag machine with four-color printing inline can complete branded graphic printing and bag making on the same production line and is suitable for producing bread bags, toast bags, snack takeaway bags, and nut and snack bags. After roll paper printing and drying, the material enters the bag-making section directly, where creasing, gluing, cutting, bottom folding, and collection are completed continuously. This eliminates post-printing rewinding, temporary storage, and secondary material loading, making it easier for packaging enterprises to coordinate printing and bag-making schedules.
The machine is compatible with greaseproof paper, food-grade kraft paper, coated composite paper, and other materials. When processing thin paper or coated paper with a relatively smooth surface, operators can adjust unwinding tension according to material characteristics. The photoelectric positioning system corrects lateral web deviation, while the multi-axis servo system coordinates paper feeding and cutting, helping maintain consistent alignment between printed graphics and bag body crease lines. For oily pastries or fried snacks, greaseproof paper and an adhesive suitable for the paper surface can be selected, with adhesive application adjusted to help achieve uniform bonding along the bag sides and bottom.
The touchscreen interface can store multiple sets of bag-making parameters. For repeat orders of the same paper bag, operators can recall the existing settings, verify bag length, four-color print registration, and bottom sealing conditions through a trial run, and then proceed with batch production. When changing branded printing layouts, the same bag specification parameters can be retained, reducing repeated setup. Alarm and shutdown functions triggered by material shortage, paper jams, overloads, or positioning deviations allow operators to troubleshoot abnormalities in a timely manner, while the enclosed protective cover and automatic lubrication system facilitate routine workshop cleaning and maintenance.
