How Do Pouch Packaging Machines Work

Pouch packaging is a multi-function equipment whose main function is to wrap products in a specific type of packaging material which are pouches.

Although there many designs available in the market, the working principle of pouch packaging machine remains virtually the same.

Let’s have a quick look at how pouch packaging machine works:

Working Principle of Pouch Packaging Machine

Also referred to as pouch filling and sealing machine, the working process involves series of operations.

Every operation ensures your products are securely packaged and sealed.

Let’s look at these critical steps:

· Film Pulling System

The first step carried out by this machine is film-pulling which is carried out by servo motors that control the length of the film and a tensioner to control the tension of the pulled film.

These components ensure that the pulling process is accurate and streamlined to prevent jerks that can lead to losses. The film typically used by this equipment is generally designed from materials such as aluminum foil, laminated PE, or PET.

This film is put on a component called an unwinding roller located at the back of the machine and its function is to feed the film into the system.

When placing the film, it is vital that you properly align the film to ensure that the process following are properly conducted. Your alignment can directly disrupt every other step involved in the packing process.

Printing

Although this is not a vital step in the overall packaging process and is optional it is a way of building your brand awareness and increasing the visual appeal of your product.

The type of product you work with is equally an important factor as most products require a description on the wrapping. This information can include its ingredients and other relevant information like the batch codes, date of manufacture, and the weight of the product.

You should get a printer that can easily be integrated into your packing machine as not all machines may include this feature. Some equipment is equipped with inline printing that allows you to print onto the film.

There is also an online laminate roll printer variation so you can also incorporate various software for creating labels and barcodes, these software elevate and ease the printing process.

Pouch Forming

The third step in the wrapping process involves the assembling of the desired pouches that are to be utilized in the process. It is important to note that not all machines can conduct this process as others require pre-made pouches which brings a distinction in the packaging process.

This pouch formation procedure involves having the overlapped edges of the film pulled into the desired shape and its bottom and vertical openings closed by sealing jaws.

There are two mainly utilized variations which include the following.

Premade Pouches

These are pouches that have already been assembled typically by secondary producers. In this case, the need for creating your pouches is eliminated and it helps save on the production time.

Form Fill Seal Pouches

In this variation, the end packaging material is derived from the film incorporated into the machine’s working mechanism. This is done by form-fill-seal machine variations that are designed for this purpose.

Filling & Sealing

The next in this packaging process is the filling of the pouches with your product. A designated station is utilized for this purpose during which your desired product is automatically distributed into the packaging material.

This process is carried out by varying types of fillers such as auger fillers, multi-head scales, or liquid fillers depending on the properties of your intended product.

Different types of seals can be incorporated into these machines, including lap seals, fin seals, or gusseted seals which are used depending on the properties of your product. Your seals must be of a high quality and are strong to maintain the integrity of the package and the products contained within it.

Pouch Cutting

The next stage involves the cutting and shaping of the pouches into individual units. This is the final step carried out by the machine in the packaging process.

Remember, the packaging film used is typically a continuous roll and relies on the cutting mechanism to separate the roll into separate pouches. This final step is important as it determines the final shape of the pouch.

There are a variety of components included in the cutting station and these may vary depending on the type of packaging machine you have.

These types of equipment include various types of blades with varying dimensions such as specific pressure line spacing, blade diameter, and blade thickness. These blades are essential in creating uniform and precise cuts for every individual pouch.

Control Cabinet

This is a section typically designed onto the side of the pouch packing machine. It contains all the components essential for the smooth and continuous operation of the packaging machine. This cabinet contains vital electrical parts such as low-pressure electrical parts, solenoid valves, pneumatic cylinders, servo motors, contactors, and a Programmable Logic Controller(PLC). The components contained in this cabinet are essential as they control and coordinate all the functions performed by the pouch packaging machine.

At JOCHAMP, we have a range of pouch packaging machines designed to meet specific needs of every client. Among our top selling pouch packaging machines include Spout pouch filling machine, Tobacco pouch packaging machine, High speed pouch packing machine, Horizontal pouch packing machine, Premade pouch packing machine, Zipper pouch packing machine and Stand up pouch packing machine.

Even with these machines, how pouch packaging machine work remains virtually the same. The variation on the pouch packaging process come mainly during sealing process.

Conclusion

There are different variations of this machine some of which have been modified and designed to be suitable for products with specific characteristics. It is therefore important that you select a machine that is compatible with your intended product and addresses all your application requirements. When selecting this equipment, you should consider additional systems that allow you to streamline your packaging process such as printers, and ensure that they are compatible.
