For your guidance review the table containing the categories of sachet packing machines and ensure you know the 8 things you must consider before purchasing a sachet packing machine later in this article.

Sachet Packaging Machine Style

Here’s a step by step guide on how a sachet packaging machine works;

Packaging Rollstock Film Unwinding and Transport

The process begins by unwinding a large roll of pre-printed film material from roll stock. 

The film material is wound up into a reel around a core that’s located at the rear end of the sachet packing machine.

The film material is commonly made from polyethylene, cellophane laminates, paper laminates, and foil laminates depending on the industry preference. 

The film is most commonly pulled from the reel by film transport belts that are positioned on the side of the tube that forms the bags from the film material.                   

Some machine models that do not use transport belts have sealing jaws to move the film into the forming area. The jaws grab the film and move it downwards from the reel into the bag forming zone.

Maintaining Film Tension

As the film unwinds from the reel, it is ordinarily prone to sag if it’s loosely held, making it wander as it moves through the sachet packing machine.

Filming Material Under Constant Tension

To ensure this does not happen, a series of brake rollers move it up and down, applying regular pressure, to ensure the film is under constant tension. 

Film Centering

Optical sensors located in the machine detect the positioning of the film on the transport belt. They ensure it is perfectly centered. This mechanism autocorrects any wandering of the film by re-centering it. 

Film centering and maintenance of constant tension is critical. This is because it will ensure that perfect sealing and cutting of sachets is realized. Perfectly cut sachets have properly aligned graphics.

Optional Printing or Embossing

The film moves through this section if a printing unit has been attached to the sachet packing machine. Thermal ink or ink-jet printers can be used here. You’ll find this section useful if you need to print dates, registration marks, logos, or infomercials on the package.

Sachet Formation

Sachet Formation on Sachet Packing Machine

The film then moves to the sachet-forming tube. The film wraps around the forming tube until the opposite ends meet. They form what looks like a continuous tube of filming material.

The conical tube forms the sachet into the correct size. It then seals the base of the sachet and the converging ends where a vertical seal is applied. 

The width of your sachet is determined by the size of the forming tube. Where you need to produce sachets of different width, replace the forming tube on the sachet packing machine with one that corresponds to the required width.

The length of the sachet can be varied by adjusting the sachet length dimensions on the machine’s operational interface. 

Materials Filling Into the Sachet

Once the sachet has received a bottom and vertical seal, filling with contents begins. 

The sachet packing machine is tightly integrated with a filling mechanism that releases granular, liquid, or powder contents into the sachet via round tubes, flat nozzles, or auger fillers. 

The filling system is responsible for the accurate weighing of contents to ensure the quantity dispensed is exact. A volumetric cup, a liquid pump, or an auger filler are used to weigh the contents being packaged.

The sachet packing machine automatically synchronizes its operations so that the product is automatically released when the sachet opens.

Sugar Packaging Machine

Sachet Sealing

The sachet at this point is already sealed vertically and at the bottom. The top portion is what remains to be sealed after receiving the contents.

Sealing of the top part of the sachet happens when a set of horizontal jaws come together to heat-seal the sachets. Note that sealing the top of one sachet creates the base for the next sachet on the packaging line. 

A sachet packing machine that operates constantly without having to pose for an action to be executed is referred to as a continuous motion machine. In that case, the sealing mechanism has constant contact with the packaging film as it passes through the sealing area. 

A continuous motion machine has faster output than an intermittent motion packaging machine and is recommended for high-speed production.

Heat sealing may not be appropriate for industries where products are heat sensitive or need to be packaged in a frozen state. Ultrasonic sealing that makes use of vibration is often used for “cold sealing”.

Synda Pack’s sachet packing machine comes with an easy tear notch and variable seal patterns

Sachet Discharge

Sachets Discharged From a Multi-lane Sachet Packing Machine

Finally, the sachet that has been filled and sealed is discharged from the machine. It is now ready for further packaging and distribution. As sealing occurs, a sharp knife located inside the sealing jaws cuts off the sachet. After that, it is released for onward transmission. 

The sachets are released into an outfeed conveyor or a container. 

Sachet-packing machines can produce 30-60 sachets in a minute depending on the type of machine and the sachet used. 

Post-Discharge Operations

The sachet may need to undergo specific quality control tests to confirm the packaging aims have been achieved. The sachets may go through check weighers or metal detectors, and x-ray machines depending on your industry.

The sachets may be further consolidated through a case or carton packaging. Then it will be containerized for transportation to your warehouse or consumers.

What is a Multi-lane Sachet Packing Machine?

A multi-lane sachet packing machine is being used to create several strips of sachets. The process will be based on the same principles above but would differ slightly. 

Here’s what happens;

  • The packing film material is cut into several strips as it is pulled into the sachet-forming area. The number of strips cut is based on the number of sachet packing lanes on the machine.
  • The sachet strips made in the previous step move around several forming tubes forming a long sachet strip.
  • The filling, sealing, and discharging process occurs simultaneously along the several forming tubes in the same manner already explained in the above processes. 

Here’s a video demonstrating how a multi-lane sachet packing machine operates.

Can a Sachet Packing Machine Handle Different Products, Sachet Sizes, and Packaging Styles?

Yes, it can package different products on the condition that they are in the same status. For example, the granules products, all products are similar granules. Liquid products, all the products are liquids or paste. Powder vice verse. 

3-side-seal Sachet Packing Machine

For there are different fillers that are integrated with sachet packing machines. Liquids use piston filler or pump filler; powder uses auger filler; and granules use volumetric cup filler. 

No, it cannot package for different packaging styles in one sachet packing machine. For the sealer styles are different. There are 3 sides of seal styles, such as a 3-side-seal sachet, a center-seal sachet, and a 4-side-seal sachet.

Yes, it can pack in different sizes. This is achieved by adjusting your machine to cater to different sachet sizes and packaging styles. The process of adjusting the machine to package a different sachet size or type is called a changeover.

Sachet in Center-seal Sample

However, not every sachet packing machine is versatile enough to handle all the parameters you may want. 

Invest in a machine that is best suited for your sachet specifications. This is because machines are made to operate at best for a specific function. They can be adjusted to perform other functions, but with less efficiency.

How Much Does a Sachet Packing Machine Cost?

It’s not easy to give a specific price. This is because the price of the sachet packing machine will vary depending on the function, material, and dimension of the machine.

However, we can give a price estimate.

For an automatic sachet packing machine for small sachet dosing 5~100g granulespowder, and liquid, the price is around $3,800 per set. A 4-side seal sachet packing machine costs more than a 3-side seal at $300.

You’ll generally pay more for a more complex machine, customized, and has a higher processing speed.

How Do I Prepare my Factory for a Sachet Packing Machine?

You need to prepare well before receiving and operationalizing your machine. 

  • Ensure your workforce has the technical capacity and training to operate the machine you purchase
  • Have adequate space to allow for the sachet packing machine, the operators and storage area for contents, and shelf-ready sachets.
  • Plan for growth early as you automate your packaging. You may need more machines in the future.

Should I Buy My Sachet Packing Machine From China or the USA and Europe?

It’s increasingly clear that China is a global manufacturing powerhouse capable of producing high-quality goods at a competitive price compared to the USA or Europe. 

China has gained a high reputation as a manufacturing hub earning the name, “the world’s factory”.   There are many US and European-based companies that manufacture goods in China. 

Buying from China is a good decision.

Eight Things to Consider Before Purchasing a Sachet Packaging Machine

1. Machine versatility; Consider a machine that can handle various product lines and not just a single packaging solution.  Having a futuristic mind that accommodates business growth prospects can guide the purchasing decision.

2. The sachet type you want to produce; flexible sachet packing machines give a leeway for the production of many types of bags. Common bag types are flat, stick packs, 3-side-seal packs, 4-side-seal packs, and center seal packs.

3. What’s your required speed output; How many bags are you planning to produce per minute? Continuous motion machines have a higher output than intermittent motion packing machines. 

Small-scale sachet packaging may require manual to semi-automatic sachet packaging machines. And industrial sachet packaging machines need to produce a lot of sachets that need fully automated high-speed machines. 

  1. Choosing between ready-made pouches and roll stock film; Producing sachets from a film roll is cheaper but a preformed pouch has a classier look. Resolving what you’ll produce will determine the sachet packing machine that will suit you.
  2. Bag specifications; Your requirements should match the predefined features of a sachet-making machine that you intend to purchase. The machine you purchase should satisfy vital bag specifications such as bag size and weight.

Will you need gusseted or stand-up bags? Does your product need enhanced sealing to meet regulatory requirements?

  1. Product specifications; Consider whether your products are in liquid, powder, or solid states and if there is a need for packing at low temperatures or packing at high. Powder in fine mesh or coarse mesh.
  2. Space availability at your factory; This will determine the size of the machine that you can purchase. Space should be adequate for the machine, machine operators, other devices that may be integrated into the machine such as filling components, and a packaging area.
  3. Check if there are auxiliary (complimentary) services added to the package. A sachet machine with add-ons such as an easy tear notch, color ribbon printer, chained sachets, and a punch hole for wall display can promote your packaging outcome.
