Understanding Flow Pack Machines
How Flow Pack Machines Work
Flow pack machines operate through a continuous motion process that transforms flat film into a three-dimensional package. The process begins with the unwinding of a film roll, which is then shaped into a tube using a forming plow. The product is inserted into this tube, and the film is sealed both longitudinally and transversely to create a complete package.
Key Components
- Film Unwinding System
- Forming Plow
- Product Infeed System
- Longitudinal Sealing Unit
- Transverse Sealing Unit
- Product Output Conveyor
