The RZFD-450A square bottom paper bag machine with two-color printing inline integrates branded graphic printing and square bottom forming on the same production line. After roll paper unwinding, the material passes through two-color printing, paper feeding and web guiding, creasing, gluing, cutting, and bottom folding to produce takeaway bags, eliminating post-printing rewinding, temporary storage, and secondary material loading. Packaging enterprises can select bag specifications according to orders for milk tea, fast food, bakery products, and other applications. A handle attachment module can also be selected when producing takeaway bags with handles.
The multi-axis servo system coordinates printing, paper feeding, and cutting, while the photoelectric tracking system adjusts the cutting position according to printed registration marks so that store logos and text are positioned in the designated areas of the bag. When processing materials such as greaseproof coated paper and kraft composite paper, adhesives can be selected according to paper surface characteristics, while adhesive amount and temperature can be adjusted according to operating speed to help achieve uniform bonding along the bag sides and bottom. For orders involving multiple meal containers packed together, the bottom width and paper material can be selected according to container dimensions and total weight, followed by sample bag testing to verify load-bearing performance.
The touchscreen system can store multiple sets of specification parameters. When repeat orders for the same takeaway bag are received, operators can recall the existing settings, verify graphic position, bag length, and bottom sealing conditions through a trial run, and then proceed with batch production, reducing repeated setup time. The machine is equipped with alarm and shutdown functions for material shortage, paper jams, overloads, and positioning deviations. The automatic lubrication system and modular structure also facilitate routine maintenance and sectional inspection in the workshop.
