Product Description

Center seal four side seal automatic bag making machine

Machine Features

    This machine adopts a PLC dual-servo system with a third traction mechanism, ensuring that the material on the unwinding rack and overhead frame is continuously pulled forward by the third traction motor at a constant speed. This guarantees stable unwinding, consistent tension control, and smooth material feeding. The automatic feeding mechanism significantly reduces labor intensity.

    The entire machine features a rational structure, precision machining and assembly, and a sleek appearance. It operates with high speed, low noise, and excellent stability, making it currently the most advanced equipment in terms of performance and structural design in the domestic market.
This machine is suitable for making the following types of packaging bags:

Bag type	Max. Output	Working speed
Mid-seal bag	2 pcs	180 strokes/min
Center Seal Gusseted Bag	2 pcs
Side Seal Gusseted Bag	2 pcs
Four-Side Seal Pouch	1pc
Single-Seal Side Gusset Pouch	1pc
