Multi Head Packing Machine

What is Multi Head Packing Machine?

The multi head packing machine is actually a multi head packing line, because it includes a variety of different equipment.

Weighing and packaging are the most important processes of a multihead weigher packing machine, the multihead weigher is responsible for weighing, and the VFFS machine is responsible for packaging.

The weigher packing machine can not only accurately weigh the products, but also automatically package the weighed products, it is very efficient and easy to use.


In fact, the weigher packing machine can complete a series of processes in one stop, such as:

  • Material Feeding
  • Weighing
  • Bag Making
  • Material Filling
  • Bag Sealing
  • Date Code Printing
  • Packed Pouch Outputting

Packable Products

It is capable of packing many products in the food, pharmaceutical, daily chemicals, electronics, hardware industries.

  • Food

Puffed food, potato chips, candies, pistachios, raisins, glutinous rice balls, meatballs, peanuts, biscuits, jelly, candied fruit, walnuts, pickles, frozen dumplings, almonds, salt, sugar, red dates, oatmeal, etc.

  • Pharmaceutical & Chemical

Fertilizer pellets.

  • Daily Chemical

Washing powder.

  • Hardware

Screws, nuts, fasteners, nails.


Factors to Consider in Purchasing

When you plan to purchase a weigher packing machine, you’d better understand the following information.

Keep the following information in mind, you can find the most suitable model, and save priceless time and energy.

  • Product Type

You must clearly know the product you want to pack, know the product’s sizes, and take some clear photos of the product.

These clear photos can help suppliers quickly figure out a suitable machine.

  • Pouch Type

Common pouch types include: pillow pouch, 3 side sealing pouch, 4 side sealing pouch, gusset pouch, stand up pouch.


  • Pouch Material

Common materials for pouches are composite film, anti-static film, matte film, aluminum foil film, printed film, non-woven fabric, etc.


  • Pouch Thickness

It is the pouch material’s grammage, which refers to the material’s weight per square meter.

  • Pouch Size

With reference to the following photo, pouch size actually refers to the pouch’s total width and total height.


Multihead Packing Machine Schematic

The following photo is the multihead packing machine’s schematic:


The standard multihead weigher packing machine mainly includes the following equipment:

  • Vibrating Feeder
  • Z Bucket Conveyor
  • Multi Head Combination Weigher
  • Support Platform
  • Vertical Form Fill Seal (VFFS) Machine
  • Outfeed Conveyor

Some customers will install a gravity fall metal detector under the head weigher’s discharge chute, remove the detected metal from the waste outlet.

In addition, there are some options on the vertical form fill seal packaging machines, mainly including:

  • Inkjet Date Coding

It is able to print batch & date codes on the pouch.


Inkjet Date Coding

  • Nitrogen Flush

It is capable of filling nitrogen gas into the pouch, thus removing the oxygen from the food pouch, protecting the food inside for a longer period.


Nitrogen Flush

  • Tear Notch

It can punch a notch on the pouch’s top, then customers can easily tear open the pouch.


Tear Notch

  • Perforator

It can perforate a row of holes while sealing the pouch.

After perforating, several pieces of neighbor pouches link together, thus continuous/chained pouches appear in your eyes.



  • Hole Punch

It can punch a small hole in the pouch, with this small hole, the pouch can hang on the shelf easily.

Working Principle of Multihead Weigher Packing Machine

To better understand the multihead weigher packing machine’s working principle, please refer to the following schematic diagram.


The multihead weigher packing machine’s basic workflow is:

  • Material Feeding
  • Weighing
  • Bag Making
  • Filling
  • Sealing
  • Date Coding
  • Discharging
  • Checkweighing
  • Cartoning

Next, let me introduce the multihead weigher packing machine’s working principle in details.

Material Feeding

Generally speaking, the upstream equipment transports materials to the hopper automatically, or workers manually add materials to the hopper.

The materials in the hopper directly fall onto the feeder, the feeder vibrates the material into the infeed conveyor’s buckets.


The infeed conveyor lifts the material upward, and then dumps the material into the multihead weigher’s infeed chute.


A multihead weigher is responsible for weighing.

The materials enter the multi weigher’s dispersion feeder from the infeed funnel.


The dispersion feeder vibrates the material to each radial feeder, and the radial feeder vibrates the material to each pool hopper.


Once the last weighing cycle is over, the material in the pool hopper enters the weight hopper for the next cycle, the weight hopper’s load cell feeds back the measured weight to the PLC.

After the PLC runs the combination calculation, it determines the weight hopper combination, the determined combination is closest to the target weight.

Then PLC sends commands to the corresponding weight hoppers, releases the materials to the discharge chute.


When the timing hopper receives the release command, it will open the discharge chute and outfeed the materials to the VFFS machine’s inlet.


Vertical Form Fill Seal (VFFS)

While the timing hopper is waiting for the command to release the material, the vertical packaging machine starts to work according to the steps of form, fill, and seal.

VFFS Bagger

As shown in the figure below, the vertical packaging machine mainly consists of:

  • Film Pulling System
  • Former
  • Horizontal Sealing Device
  • Vertical Sealing Device
  • Cutting Device
  • Photoelectric Monitoring System


The film pulling system transmits the film to the forming tube, then the film passes through the collar, and two sets of high-quality pulling belts stretch it down.


Film Reel


Film Pulling System

When the machine starts at the beginning, the worker manually makes one pouch first, then cuts off the bottom bag, and the upper bag also forms into shape.

During the down-stretching process, the sealed bottom goes down, the vertical sealing bar first melts the vertical edges, bonding the film until the length reaches the preset value.


Vertical Sealing Bar

At this time, a top open pouch forms, and the timing hopper releases the material to the open pouch.

After the filling reaches the preset gross weight, the filling stops.

Then the horizontal sealing jaws seal the top of the bag, the upper bag’s bottom forms at the same time.


Horizontal Sealing Jaws

In this way, the pouch forming, filling, and sealing are completed cyclically.

Premade Pouch Filling Machine

If it is a pre made pouch packing machine, the product packaging process mainly includes the following steps:

  • Pick-up Doypack

The machine picks up a doypack to the gripper, if the photoelectric eye detects no pouch, the machine sounds an alarm.

In this way, it effectively reduces the labor intensity;

  • Print Date Code

Ribbon detection, if the ribbon runs out, alarm pops up on the touch screen, ensure the normal date coding;

  • Open Pouch

Open the pouch to detect, if the bag is not open, the machine doesn’t fill material, avoids wasting material;


Rotary Pouch Packing Machine

  • Fill Material

Inspect first, if no material, no filling and no sealing, avoids wasting bag;

  • Heat Sealing

Alarm for abnormal temperature to ensure sealing quality;

  • Cooling, Shaping & Discharging

Ensure that the seal is beautiful.

To better understand pre made pouch packing machine’s working process, please watch the below video for reference.


After the machine cuts off the pouch from the forming tube, the finished pouch drops directly onto the outfeed conveyor belt, then it forwards to the downstream equipment.


Metal Detection & Checkweighing

Generally speaking, the packed food pouches pass the metal detector first, the metal detector will detect whether the food pouches contain metal.

If detecting metal in a certain food pouch, the pneumatic pushrod will reject it to the waste collection box.


Metal Detector

The qualified food pouches forward to the checkweigher, ensuring the packaging weight is within a reasonable range.



Some food pouches don’t meet the target weight, their destination is the waste collection box.


After food pouches pass metal detection and checkweighing, they go ahead to the case packer or cartoning machine.

Multihead Packing Machine Features

As the multihead packing machine is composed of many equipment, let’s introduce each equipment’s features one by one.

Vibrating Feeder

A vibrating feeder uses motor vibration and gravity to move materials in a small range, generally distributing materials to a conveyor.


Vibrating Feeder

Vibrating feeders are popular in many industries, including:
