In the highly competitive world of packaging machines, the one remarkable machine that you can’t ignore is a sachet packaging line. From powders to gels, sachet packaging lines are redefining how pharmaceutical products are efficiently and safely packed for patient use.
Without further ado, let’s delve into the depth of sachet packaging lines, their types, working and benefits.
What is Sachet Packing Line?
Sachet Packaging line is basically different machines for packaging combined together in a single line. It is a fully automated line used for filling and sealing sachets with various products like powders and granules.
Sachets are tiny sealed packets with limited product quantities that are produced with special sachet packaging machines to ensure accurate filling and sealing. Sachet packaging offers a versatile and eco-friendly solution for modern product distribution demands.
These machines have become indispensable for most manufacturers these days. The reason behind this is the increased demand for convenient and disposable products. These are widely employed in the food, pharmaceutical and cosmetic industries.
Types of Sachet Packing Machines
There are various types of sachet packing machines used depending on the requirements and demands. Some of them are mentioned below.
1. Vertical Form Fill Seal Machine (VFFS Machine)
As the name indicates, the vertical packing machines perform their job of packing sachets in vertical form. These machines are highly efficient and budget-friendly.
These machines consist of a big film roll that takes the shape of a small bag. These bags are then filled with the product and finally sealed. All this process takes place in a vertical direction at a speed of up to 100 bags per minute. These machines are mostly used for wrapping candies, juices, powders and snacks like nuts.
2. Horizontal Form Fill Seal (HFFS) Machines
They are also known as horizontal flow wrap machines. You can automatically pack solid products in the horizontal direction with these machines. The most common products that you can pack with these machines are soaps, cereal bars and bakery products.
These are high-speed and efficient machines which are used for products that are packed in bulk.Their unique ability is that you can pack a wide variety of product sizes and shapes. Major drawbacks of these machines are that you can not use them for liquid products and they occupy larger floor space.
3. Stick Pack Machines
These machines are pretty much similar to vertical machines in function. Just like vertical machines, there is a film roll that is cut and made into the shape of stick packs. In this way, you can get up to 80 bags per minute per lane.
You can use stick pack machines for a wide variety of products, including candy bars, detergent pods, nuts and granola bars.
4. Multi lane Sachet Packaging Machines
These are the ultra high-speed production machines and are used for bulk volume packaging of different products. In these machines, all the processes of packaging are thoroughly automated. Thus, manual labour is reduced and hence there are fewer chances of errors.
In multi-lane machines, pre-made pouches are loaded into the machine through automatic systems. Then, some fillers dispense the required amount of product into these pouches. Heat sealers seal the product with high precision. These machines have integrated cutting mechanisms to detach the pouches individually. Hence, they are prepared for distribution.
The products you can pack with these machines include milk powders, pharmaceuticals, liquids, granules and sauces.
Components of Sachet Packaging Machines
The key components of sachet packaging machines are as follows :
- Filling System: The main part of this whole process is the filling of the sachets, which is carried out by filling systems. There are a variety of fillers available in the market including auger fillers, piston fillers and gravity fillers.
- Sealing Unit: This system is responsible for tightly closing the sachets when they are filled with the right product quantity. The standard sealing methods employed include ultrasonic and vacuum induction.
- Film Transportation: The main purpose of this unit is to make sure that the sachets move smoothly throughout the entire process of packaging. It also monitors the alignment of films.
- Monitoring Unit: This system supervises the entire process of sachet packaging. It verifies proper filling and sealing of the sachets with maximum efficiency.
Working of a Sachet Packaging Machine
Now that you have understood the concept of the sachet packaging line, let’s get into the details of the working of sachet packaging machines.
Mechanism of Sachet Packaging Machines
Let’s move on to how these machines work step-by-step.
- Feeding the product: In the first step, you have to place the product inside the sachets on the conveyor or belt of the machine. Then the sensors inside the machine will automatically position the product.
- Feeding the film: In this step, you will place a roll of film on the unwinding roller. You can use the film according to your packaging needs, for example, plastic, laminated or aluminum foil. Then the machine pulls the film into it through a tensioner along with the motor.
- Forming the package: The films then move the sachets toward sachet forming stations. In this station, there are sealing jaws that seal the corners of the sachets for filling the product into them.
- Filling the product: Now the sachets are filled with the required amount of product. Depending on the type of machine being used, the product is filled longitudinally or horizontally.
- Sealing of sachets: Then the machines use heat and adhesives to seal the filled sachets. You have to make sure that the sachets are airtight and sealed appropriately for distribution.
- Cooling the sachets: You have to use an air-blowing device to cool the sachets after you have completed all the steps of packaging. This is done to prolong the shelf-life of the product.
- Cutting and discharging sachets: This is your last step in sachet packaging. Each sachet is cut and then collected in a detection device for final packaging.
Benefits of Sachet Packaging
Sachet packaging lines have become essential in the modern packaging industry. They offer a variety of benefits for businesses globally. Some of them are as follows:
- These packaging lines are highly efficient, making them a perfect choice for your business as they are automated.
