Form Fill Seal Machines Diagram

With reference to the following schematic 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 the 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 tension for the film unwinding.

  • Photoelectric Sensor

Detect the color mark on the film, and 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, and 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 roll of 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, and filling equipment, vertical form fill seal machines are suitable for packaging blocky, flaky, granular, stalk, powder, liquid, and viscous liquid materials.


Multihead Weigher

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
  • Bag Former
  • Metering Device
  • Horizontal and Vertical Sealing Device


With reference to the following video, let’s summarize the working principle of the vertical packaging machine.


The jumbo 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 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 seal the top opening and cut 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 Discharging

Types of FFS Machines

By Bag Forming Direction

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

  • Vertical Form Fill Seal Machine

The bag former is perpendicular to the ground, and the plastic film is pulled down from top to bottom through the forming tube, forming a shaped pouch.

  • Horizontal Form Fill Seal Machine

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


By Packed Products

According to the different materials packed 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

By Bag Shapes

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, and 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.

Bag Forming

Unwind the film jumbo 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, seals the two vertical seams, and the upper part is open.


Film Reel

Product Filling

The product drops from the metering device into the formed bag via the upper opening, the metering device needs to be purchased additionally.

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


Auger Weigher

Bag Sealing

After the material filling’s completion, the horizontal sealing jaws seal the upper part of the forming bag and also form the next bag’s bottom seal.


Horizontal Sealing Jaws

Bag Cutting Types

Vertical packaging machines generally have two cutting methods:

  • Eye Mark Cutting
  • Fixed-length Cutting

The two cutting methods are easy to switch, and the cutting method choice depends on the packaging film.

The packaging film is either with an eye mark or not.


The packaging film without an eye mark is cut to a fixed length; otherwise, it is cut by detecting the eye mark via a photoelectric sensor.



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.

Overheating causes the film to wrinkle or even burn through.
