Form Fill Seal Machines Diagram

With reference to the following schematic diagram of a vertical form fill seal machine, let’s introduce its main components one by one.


  • Film Unwinding Shaft

The tension of the dancer roller drives the unwinding shaft to rotate for plastic film unwinding.

The brake device installed on the shaft receives the PLC signal to control the unwinding process.

  • Tension Control Dancer Roller

It generates the tension for film unwinding.

  • Photoelectric Sensor

Detect the color mark on the film, control the stroke of the film.

  • Rotary Encoder

The rubber roller follows the rotation of the film, drives the encoder to rotate, rotary encoder detects the actual stroke of the film.

  • Inkjet Printer

Coding equipment, receive PLC signal to print date and batch number on the film.

  • Film Pulling Shaft

Follow the rotation of the main shaft and pull the film down at a constant speed.

  • Vertical Sealing Bar

After the film has passed through the forming tube, the bag has taken shape, the two outer edges of the film overlap each other.

Then the vertical sealing bar seals the outer edges and presses down, completing the vertical heat sealing.

  • Product Inlet

The product weighed by the dosing equipment enters the vertical form fill seal machine from this port.

  • Horizontal Sealing Shaft

Drive the horizontal sealing jaws to stick to the plastic film for sealing cyclically.

  • Horizontal Sealing Jaws

They seal the formed bag’s top opening and cut it off, at the same time, form the next bag’s bottom seam.

  • Horizontal Sealing Jaws Driver

Drive the horizontal sealing jaws to move up and down to achieve continuous sealing.

How Does FFS Machine Work?

FSS machines include horizontal and vertical types, and their working principles are quite similar.

Vertical form fill seal machines are relatively more common, so let’s take a form fill seal machine as an example, explaining how it works in detail.

The vertical form fill seal machine converts a rollstock flexible packaging material into a bag, fills the product, and then seals the bag. One machine completes these three processes in succession automatically.

Combined with the upstream metering, dosing, filling equipment, vertical form fill seal machines are suitable for packaging blocky, flaky, granular, stalk, powder, liquid and viscous liquid materials.

The VFFS bagging machine’s product inlet is located inside the bag maker, the machine carries out bag making and product filling vertically from top to bottom.

It mainly consists of:

  • Transmission System
  • Film Pulling System
  • Product Inlet
  • Former
  • Metering Device
  • Horizontal and Vertical Sealing Device

The working principle of the vertical packaging machine is summarized as follows:

The roll film placed on the unwinding shaft passes through the guide roller and the tensioning device, the trademark on the film is detected by the photoelectric sensor, and then rolled into a film cylinder through the forming tube surface.

First, the vertical sealing bar seals the film cylinder’s longitudinal adjoining edges, thus obtaining a sealed bag with a top opening.

The metering device fills the measured products into the top-open bag through the product inlet, and then the horizontal sealing jaws seals the top opening and cuts it off to get a packaging bag, and at the same time, form the bottom seal of the next bag.

To sum up, the workflow of the vertical form-fill-seal machine mainly includes the following steps:

  • Film Unwinding and Transmission
  • Film Tensioning
  • Date & Batch Number Printing
  • Film Tracking
  • Bag Forming
  • Product Filling
  • Bag Sealing
  • Bag Dischaging

Types of FFS Machines

According to the direction of bag forming, FFS machines include the following two kinds:

  • Vertical Form Fill Seal Machine

The bag forming tube is perpendicular to the ground, and the plastic film is pulled by the film pulling shaft from top to bottom through the forming tube, forming a shaped bag.

  • Horizontal Form Fill Seal Machine

The rectangular bag forming tube is parallel to the ground, and the plastic film is pulled by the film pulling shaft from left to right through the forming tube, forming a shaped bag.

According to the different properties of the materials contained in the bags, the FFS machines mainly include the following three types:

  • Granule Filling Machine
  • Powder Filling and Sealing Machine
  • Liquid Filling and Sealing Machine

According to the different shapes of forming bags, FFS machines mainly include the following categories:

  • Pillow Pouch
  • 3 Side Seal Pouches
  • 4 Side Seal Pouches
  • Gusset Pouch
  • Flat Bottom Pouch
  • Standup Pouch (with zipper/spout/euro slot/handle, etc.)
  • Doypack

VFFS Packing Machine

There are two types of VFFS packing machines: continuous motion and intermittent motion.

The continuous motion VFFS packing machine can achieve continuous sealing without stopping, its packing efficiency is higher;

The intermittent motion VFFS packing machine requires a short pause every time it seals, its packing is less efficient, but it’s cheaper.

The working principles of these two VFFS packing machines are basically the same, it mainly includes three steps.

  • Bag Forming

Unwind the flexible film roll, the film enters the forming tube after being driven by the guide roller and the dancer roller. The film forms a round bag on the forming tube, and seals the two vertical seams, and the upper part is open.

  • Product Filling

The product is dropped from the metering device into the forming bag via the upper opening. The metering device needs to be purchased additionally.

Usually, a multi-head scale is used for granular materials, an auger weigher is used for powder materials, and a metering pump is selected for liquid materials.

  • Bag Sealing

After the material filling is completed, the horizontal sealing jaws will seal the upper part of the forming bag and also form the bottom seal of the next bag.

Vertical packaging machines generally have two cutting methods, namely, mark cutting and fixed-length cutting. The two cutting methods are easy to switch, and cutting method option depends on the packaging film.

The packaging film is either with a photo eye mark or not. The packaging film without a photo eye mark is cut to a fixed length; otherwise, it is cut by detecting photo eye mark.

In most VFFS machines, the vertical sealing bar and horizontal sealing jaws consist of a nichrome wire, the wire has an intermittent current flow through it, it heats the sealing bar and jaws to the proper temperature.

It is necessary to carefully adjust this temperature, as well as the dwell time, to provide enough heat at the ideal temperature to melt the plastic without overheating.

This is to avoid overheating causing the film to wrinkle or even burn through.
