How Does Sauce Packing Machine Work?

Sauce Packing Machine


To begin with, we must understand what a sauce packing machine is.

The vertical design of this machine makes it perfect for making and filling sachets. It is often used for industrial sauce packaging and processing, offering a more practical and efficient method of automated packaging while also saving a significant amount of time and money. 

A sauce packaging machine may make and fill pouches, print, and keep track of inventory all at once. The smooth operation of this VFFS machine is ensured by the servo motor film pulling and automatic bias adjustment that occurs during film pulling. The pneumatic cylinder is applicable for both horizontal and vertical sealing, and it moves reliably.

What Makes Up a Sauce Packing Machine’s Main Parts?

This vertical form-fill-seal machine consists mainly of the following parts:

  1. Film Pulling System
  2. Optional Printer
  3. Pouch/Bag/Sachet Maker
  4. Pouch/Bag/Sachet Filling and Sealing
  5. Pouch/Bag Cutting
  6. Control Cabinet

Understanding the machine’s structure and primary parts will be more beneficial. The operation of the sauce packaging machine will then be clearer. Now let’s go right into the topic at hand.

How Does A Sauce Packing Machine Work?

In most cases, knowing how this machine transforms a roll of film into a pouch for sale would be enough. To begin, it takes a massive roll of plastic film, often compounds plastic film, and shapes it into a pouch before filling it with the products and then sealing it. This whole operation is performed vertically at a rate of up to 40 bags, pouches, or sachets per minute.

Film Pulling System

A tensioner and unwinding roller make up this mechanism. The roll of film describes the lengthy, rolled piece of film. Film types often used in this vertical form fill seal machine include laminated polyethylene (PE), polyethylene terephthalate (PET), paper, and aluminum foil. The unwinding roller at the back of the sauce packaging machine is where the roll stock film will be positioned.

The film-pulling system’s servo motor drives and pulls the film from the reels. It seamlessly syncs with one another and pulls continuously, effortlessly, and dependably.

Optional Printer 

Once the film is in the printer’s position, the photo eye will pick up the tag’s rich color and read it. The film will get a stamp with the time and batch number. There are two common kinds of printers: the traditional black-and-white ribbon model and the color TTO (Thermo Transfer Overprint) kind.

Pouch/Bag/Sachet Maker

The bag forming receives the film after the printing process. It resembles a collar on a person’s shirt.

This bag maker or former may create a variety of bags or pouches. With various bag previous sizes, you may create different bag sizes. It must switch out the forming cube to package bags of multiple sizes. It merely takes a few minutes to switch it around.

The bag former or maker features a filling function in addition to its bag-forming role. Through it, the product material will be poured into the bag. Stainless steel construction guarantees that the bag former is safe for use with edible items.

Pouch/Bag/Sachet Filling and Sealing

For this machine, there are two sets of sealing devices. The first one seals vertically, while the second seals horizontally. It may create a vertical pattern with two vertical sealing jaws.

A flat or net pattern will result from using a single vertical sealer and pressing down on the bag forming. The sealing patterns that various sealers may achieve vary. Bulk products will be weighed and filled into the bags upon bag sealing.

Pouch/Bag Cutting

The horizontal sealers of this machine include a cutter. After sealing, it cuts the pouch’s edge along the flat bottom. 

Now let’s go on to the machine’s subsequent operation.

Control Cabinet

This bag packaging machine has a control cabinet that is attached to the side. It houses all the electronic components within. Pneumatic cylinder, solenoid valves, contactors, PLCs, servomotors, low-pressure electrical components, and PLCs in expanding mode. HMI (Human-Machine Interface) is on the outer control console of the cabinet.
