Premade Pouch Packaging Machine, 2-Nozzle Filling-180DG

When I help a customer choose a pouch packaging machine, I rarely start with the machine model. I start with the product, the pouch, and the production target. That is because a packaging machine can look perfect on paper and still perform poorly if the filling system does not match the material or if the pouch is difficult to feed.

Our Premade Pouch Packaging Machine, 2-Nozzle Filling-180DG is built around this practical idea. I use the machine to automate the main steps involved in handling finished pouches: pouch feeding, pouch opening, product filling, optional air removal or nitrogen flushing, heat sealing, coding when required, and finished pouch discharge.

Unlike a roll-film form-fill-seal machine, this system does not make the pouch from film during the packaging process. It works with premade pouches that have already been cut, formed, and printed. This makes it especially useful for brands that care about package appearance, operate several SKUs, or want to change between different finished pouch designs.

At Shanghai Huacheng Packing Machinery Company (Huapack), we have focused on pouch packaging machinery since 2015. Based in Songjiang District, Shanghai, we combine research and development, manufacturing, sales, and technical service. I work with customers not only on individual pouch machines, but also on complete weighing, filling, sealing, and turnkey packaging lines.

The 180DG uses a two-nozzle filling configuration. For suitable products and filling systems, two filling points can be used within the filling station to support higher filling productivity. The actual output still depends on the complete machine cycle, product properties, pouch size, filling weight, and sealing requirements.

1. Why I Use a Premade Pouch System for Flexible Production

A premade pouch packaging machine solves a very specific production problem: the pouch already exists, and I need to fill and seal it reliably at production speed.

This sounds like a small difference, but it changes the whole packaging process.

With roll film, the machine must form the pouch before filling. The film needs to be guided, shaped, sealed, cut, and controlled. With premade pouches, those pouch-forming steps happen before the pouch reaches the filling machine.

This is a good fit when a customer already buys finished printed pouches from a flexible packaging supplier.

For example, imagine a food company selling five flavors of snacks. Each flavor has its own printed pouch. The machine does not need to print the artwork or create the pouch from a film roll. Instead, the operator prepares the correct finished pouches and loads them into the automatic pouch feeder.

The machine then handles the repetitive work.

1. It picks a finished pouch.

2. It transfers the pouch into the correct position.

3. It opens the pouch.

4. It fills the product.

5. It performs optional vacuum or nitrogen functions when required.

6. It seals the pouch.

7. It can add production coding when configured for it.

8. It sends the finished pouch to the next stage.

For me, the biggest advantage is flexibility. The customer can prepare different printed pouch designs for different products while using the same basic packaging platform, provided the pouch sizes and machine configuration are compatible.

2. How the 2-Nozzle Filling-180DG Works

I divide the working process into several simple stages because it makes troubleshooting much easier.

Automatic pouch feeding

The finished pouches are placed into the pouch magazine. The automatic pouch feeder separates individual pouches and transfers them into the packaging cycle.

This step is more important than it may look.

Different pouches have different surface friction, thickness, stiffness, zipper structures, and material combinations. A very soft pouch can behave differently from a stiff aluminum foil pouch. A stand-up pouch can also behave differently from a flat pouch.

That is why I recommend testing the customer's actual pouch rather than relying only on a drawing or photograph.

Pouch opening and positioning

Once the pouch reaches the working station, it needs to be positioned correctly and opened.

The opening mechanism must hold the pouch without damaging the material. At the same time, it must create enough opening space for the filling nozzle.

The PLC control system coordinates the timing between these actions. Servo mechanisms can also be used for controlled movement where accurate positioning is required.

Two-nozzle filling

The central feature of the 180DG is its two-nozzle filling arrangement.

For a suitable product and filling method, two filling nozzles allow the filling station to handle two filling points within the machine cycle. This can improve filling productivity compared with a single-nozzle configuration.

However, I do not tell customers that two nozzles automatically mean twice the complete machine output. That would be too simple.

The full machine still has to feed, open, fill, transfer, seal, and discharge the pouch. If the product takes a long time to fill, or the pouch requires a longer sealing period, those steps can limit total output.

So when I calculate production capacity, I look at the complete cycle rather than only the number of nozzles.

Optional vacuum or nitrogen flushing

Some products benefit from controlling the air inside the pouch.

For suitable applications, we can configure vacuum or nitrogen flushing functions. These options are selected according to the product, pouch material, storage requirements, and customer's packaging process.

I prefer this approach because an optional function should solve a real problem. There is little value in adding equipment that the product does not need.

Heat sealing

After filling, the pouch moves to the sealing station.

The sealing process uses controlled heat and pressure to close the pouch mouth. The correct settings depend on the pouch film structure. A good seal is not simply a matter of increasing temperature.

If the temperature is too low, the seal may be weak. If it is too high, the pouch material can be damaged. Sealing pressure and dwell time also matter.

Product contamination is another issue. If powder, sauce, or paste reaches the sealing area, it can affect the final seal.

Finished pouch discharge

Once sealing is complete, the finished pouch leaves the packaging machine and can move to a conveyor, Checkweigher, inspection station, carton packing system, or another downstream process.

3. Features I Consider Important on the 180DG

Two-nozzle filling configuration

The two-nozzle arrangement is useful for manufacturers looking for more filling productivity without simply moving to a much larger packaging system.

It is suitable for a range of products when the selected filling method matches the material.

PLC touchscreen control

We use a PLC-based touchscreen control system so operators can manage the main machine functions from one interface.

I want operators to understand what the machine is doing. In a busy factory, complicated controls can become a real headache.

The touchscreen approach also makes it easier to manage different production settings when the same machine is used for multiple SKUs.

Servo-controlled movement

Accurate pouch positioning matters throughout the process.

The pouch must arrive at the opening station correctly, meet the filling nozzle at the right position, and move to the sealing station without unnecessary movement.

Servo mechanisms help us control these actions with repeatable positioning and timing.

Multiple pouch formats

Depending on the final configuration and actual pouch testing, the machine can be adapted to suitable formats such as:

• Stand-up pouches

• Zipper pouches

• Spout pouches

• Aluminum foil flat pouches

• Other customized premade pouch designs

I deliberately say “suitable” because pouch compatibility cannot be judged by the pouch name alone. Dimensions, material thickness, stiffness, opening design, zipper position, and seal structure all affect machine performance.

Multi-SKU flexibility

This is one of the reasons I recommend premade pouch systems to growing brands.

A customer may have different pouch designs for different flavors, sizes, or products. The machine can be configured for flexible production and convenient specification changes within its applicable range.

This is particularly useful when a factory does not want to build a completely separate packaging line for every SKU.

Optional coding

When required, a coding system can be integrated to print production dates, batch numbers, expiry information, or other manufacturing information.

The actual coding solution depends on the pouch surface and the required print quality.

4. Matching the Filling Method to the Product

When customers ask me whether the 180DG can package a particular product, I want to know more than the product name.

I need to understand how the material flows.

For example, “powder” is not one single type of material. A fine nutrition powder may behave very differently from a coarse herbal powder. Likewise, “liquid” can mean anything from thin water-like material to a thick sauce.

Source: Huapack application engineering classification based on the product information supplied for this machine. The final filling method must be confirmed using the customer's actual material.

For granules, I check particle shape, size, density, and flow behavior. Nuts, seeds, and irregular snacks can move differently through a hopper.

For powders, I pay close attention to flowability and dust. Some powders flow easily, while others can bridge inside a hopper or create dust around the pouch opening.

For liquids, viscosity and foaming are important. A thin liquid may need a different nozzle shut-off design from a thick sauce.

For pastes and gels, I look at how the product starts and stops flowing. If the product keeps hanging from the nozzle after filling, it can reach the sealing area and affect package quality.

This is why product testing is an important part of our equipment selection process. I would rather test the material than make a guess based on its name.

5. Where I See the 180DG Being Used

Food and snack packaging

Food is one of the most common applications for premade pouch packaging.

Depending on the filling configuration, the machine can be used for products such as nuts, seasonings, seeds, snacks, sauces, and other suitable food materials.

Finished printed pouches also give food brands a clean and consistent package appearance. The artwork is already on the pouch, so the packaging machine focuses on feeding, filling, and sealing.

Health and nutrition

Health nutrition products can be packaged in premade pouches when the appropriate dosing and hygiene arrangements are selected.

For powder products, I pay particular attention to dust control and filling accuracy. For granular products, particle size and flow characteristics become more important.

Pharmaceutical and medical nutrition

Selected pharmaceutical, herbal, and medical nutrition products can use premade pouch technology when the machine configuration and production environment meet the customer's requirements.

For regulated products, I do not treat the packaging machine as an isolated purchase. Cleaning, contact materials, production conditions, validation requirements, and destination-market regulations should all be considered during the project.

Personal care and cosmetics

Personal care products such as cleansers, gels, creams, and selected liquid formulations are suitable applications when the correct pump and filling arrangement is used.

The product's viscosity is often the first thing I want to test.

Pet food

Pet snacks, dry pet food, seeds, and selected powders can be considered for premade pouch packaging.

Irregular pet treats may need careful weighing and feeding tests because their size and shape can affect the dosing process.

Seeds, agrochemicals, and small hardware

Seeds and selected agricultural materials can be packed into appropriate premade pouches. Agrochemical applications require additional attention to material compatibility, operator protection, cleaning, and applicable regulations.

Small hardware such as screws, clips, and fittings can also be packaged by counting or weighing, depending on the production target.

6. How We Build the Machine Around Real Production Conditions

At Huapack, I do not think a machine should be chosen from a model number alone.

Before confirming the equipment, I want to know:

• What product are you filling?

• What is the target filling weight?

• How many pouches do you need per hour?

• What is the pouch width and length?

• What material is the pouch made from?

• Is it flat, stand-up, zipper, or spout type?

• How many SKUs will use the machine?

• Do you need vacuum or nitrogen flushing?

• Do you need date or batch coding?

• What equipment will be installed before and after the pouch machine?

These questions may seem basic, but they prevent many expensive mistakes.

For example, knowing that a customer wants to pack “100 g of sauce” is not enough. I need to know the sauce viscosity, whether it contains particles, how it flows, whether it foams, and whether it drips after filling.

We then match the product to the filling system.

During manufacturing, the pouch feeder, opening station, filling unit, servo mechanisms, sealing section, electrical control system, and discharge system are treated as parts of one complete process.

I also consider future line integration. A customer may start with one premade pouch machine and later add a checkweigher, metal detector, conveyor, coding system, carton packing machine, or other downstream equipment.

Because Huapack also develops complete packaging lines and turnkey projects, we can plan the machine around the larger production system instead of looking at the pouch machine as a stand-alone unit.

7. Why I Choose Huapack for Premade Pouch Packaging Projects

Shanghai Huacheng Packing Machinery Company was established in 2015 and is located in Songjiang District, Shanghai.

Our business combines R&D, manufacturing, sales, and technical service under one operation. Our focus is clear: pouch packaging machinery and related packaging solutions.

Over the years, I have learned that customers are rarely buying only a machine. They are buying a production result.

They want the pouch to open correctly. They want the filling to be stable. They want the seal to look clean. They want changeovers to be manageable. They want operators to understand the controls. And when the production line becomes more complex, they want the different machines to work together.

That is why our work covers both individual equipment and complete projects.

Our capabilities include:

• Premade pouch packaging machines

• Automatic pouch feeders

• Granule and powder filling systems

• Liquid and paste filling solutions

• Vacuum packaging functions

• Nitrogen flushing systems

• Coding integration

• Automatic weighing

• Complete pouch packaging lines

• Turnkey packaging projects

I also believe customization should be practical.

If a customer has a standard pouch and a simple product, I do not see a reason to make the machine unnecessarily complicated. If the customer has unusual pouch dimensions, several products, difficult materials, or a demanding production line, then customization can make a real difference.

Our approach is to design around the customer's product characteristics, pouch format, capacity requirements, and production process.

Build the 180DG Around Your Product, Not the Other Way Around

I see the Premade Pouch Packaging Machine, 2-Nozzle Filling-180DG as a practical solution for manufacturers that want reliable automation for finished pouch packaging while keeping room for different products and package designs.

The two-nozzle filling arrangement gives the machine a useful productivity advantage for suitable applications. The automatic pouch feeder reduces repetitive manual handling, while PLC touchscreen control and servo-driven mechanisms help coordinate the different working stations.

More importantly, the machine is flexible enough to become part of a larger packaging system.

Whether you are packaging snacks, nuts, seasoning, nutrition powder, sauce, personal care products, pet food, seeds, or another suitable product, I recommend starting with the real material and pouch rather than simply choosing a machine from a catalog.

Send us your product details, filling weight, pouch dimensions, target capacity, and required functions. If you can provide product and pouch samples, we can evaluate the filling, feeding, opening, sealing, and discharge processes more accurately.

That is how I prefer to develop a pouch packaging solution: understand the production problem first, select the filling technology second, and then build the machine around the customer's actual operation.
