There are different types VFFS packaging machine, for powder, liquid and particles. Although their packaging ranges are different, but the working principle is basically the same. Here we take the powder packaging machine as an example to show the vffs packaging machine working principle.

Film rolls, guide rods and tensioning devices placed on supporting devices, after detecting the position of the trademark pattern on the packaging material by the photoelectric detection and control device, it is rolled into a film cylinder and wrapped on the surface of the filling tube by a lapel former.

First, a sealed tube is obtained by longitudinally heat-sealing the film, and then the cylindrical film is moved to a position where it is heat-sealed transversely and sealed transversely to form a packaging bag. The metering device fills the material into the packaging bag through the filling tube, and then seals the other end through the transverse heat sealing device to form a complete packaging unit.

The above is the working principle of the vffs packaging machine, it is very simple, in order to better explain the working principle of the machine, we will use this video to explain.
