Answer:

Vertical packaging machines use a single sheet of film material rolled around a core, usually referred to as rollstock. The continuous length of packaging material is referred to as the film web. This material can vary from polyethylene, cellophane laminates, foil laminates and paper laminates. The roll of film is placed on a spindle assembly at the rear of the machine.

When the VFFS packaging machine is operating, the film is usually pulled off the roll by film transport belts, which are positioned to the side of the forming tube which is located at the front of the machine. This method of transport is the most widely used. On some models, the sealing jaws themselves grip the film and draw it downward, transporting it through the packaging machine without the use of belts.
