Technical Overview of Fully Automatic Vertical Single-Film Packaging Machines

Fully automatic vertical single-film packaging machines are core equipment for achieving efficient, standardized packaging in modern industrial production, widely used in the food, pharmaceutical, and chemical industries. These machines integrate functions such as bag making, measuring, filling, sealing, and discharging, significantly boosting production efficiency.

The machine operates through automated film processing. The single-film roll is tensioned via guide rollers, then shaped into a tube by a forming collar. A longitudinal heat-sealing unit completes the back seal first. Next, the metering system (such as an auger or volumetric cup) precisely fills the product into the bag. The transverse heat-sealing jaws seal the top of the bag and cut it simultaneously, forming individual back-seal or three-side-seal bags.

These machines feature high automation. Controlled by a PLC with a touch-screen HMI, they are user-friendly and offer flexible parameter adjustments. Their compact structure saves floor space, and they are highly adaptable to various packaging films. Compared to traditional manual packaging, they not only reduce labor costs but also ensure superior sealing and aesthetics, making them an ideal choice for enterprises aiming for large-scale production.
