Its workflow is typically an automated cycle. First, the pressure head performs an initial compression, compacting the loose film and expelling most of the air. Subsequently, the pressure head may return, allowing the operator to feed in more material to increase the weight of individual bales. Then, the main compression begins, at which point the system pressure reaches its peak, ensuring the film is compressed to its maximum density. After compression, the equipment pauses, at which point the operator (on semi-automatic models) or an automatic device (on fully automatic models) threading and binding the bales with plastic rope or steel straps to firmly secure them and prevent them from springing back and unraveling.

 Finally, the pressure head fully returns to its original position, the discharge gate opens, and the packaged bales are ejected, completing one work cycle. The entire process is intelligently controlled by a PLC (Programmable Logic Controller), ensuring accurate sequence of steps and stable pressure, thereby achieving efficient and continuous operation.
