What are the five modes of the bread bag and paper bag machine?

Against the backdrop of rising environmental awareness, paper packaging has gradually emerged as an alternative to plastic packaging thanks to its biodegradable and recyclable properties. As core machinery for paper packaging production, fully automatic paper bag machine has drawn widespread industry attention for its high efficiency and outstanding precision.

The bread bag paper bag machine enables fast order changeovers. Parameters including bag length, bag width, bottom width and handle position can be set directly on the HMI without complic

ated mould replacement. It can swiftly switch between producing round-rope paper bag, flat-rope paper bag, square-bottom shopping bag and other finished products, catering to brand owners’ orders featuring multiple specifications, small batch sizes and frequent new launches. Compared with traditional separate bag-making and handle-attaching equipment, the fully automatic handle paper bag machine from Rongjian Technology stands out with its integrated design. It combines bag forming, handle sticking, cutting and material collection into one continuous production line, cutting process turnover and labour costs at the source.

In addition, the whole machine is equipped with an automatic fault diagnosis function. In case of abnormal glue position, material shortage, cutting deviation and other malfunctions, the system triggers an immediate alarm and stops for protection, helping maintenance staff locate faults rapidly. Key transmission components adopt heavy-duty durable configurations to support long-hour non-stop operation and greatly reduce downtime for maintenance.

An automatic handle paper bag machine generally consists of five major modules:

1. Feeding System: Driven by servo motors, it precisely controls the tension and conveying speed of the roll material to minimise material waste;

2. Forming System: Folds and bonds the roll material into a preliminary bag shape via hot-pressing or cold-pressing moulding;

3. Handle Installation System: Uses robotic arms or pneumatic devices to affix prefabricated handles onto the bag body at accurate positions;

4. Slitting & Cutting System: Separates individual bags with high-speed rotating blades according to preset dimensions;

5. Collection System: Automatically stacks and packs finished bags to lower manual involvement.

   
   

Throughout this workflow, the PLC control system and sensor network monitor operational conditions in real time to guarantee stable production.

From a long-term perspective for the paper bag machine sector, such integrated units also lower the entry barrier for packaging factories, empowering packaging enterprises to tap into high-demand segments with stringent aesthetic requirements, including branded gift packaging, retail packaging and food packaging.
