How a Dual-Lane Small Pouch Packing Machine Handles 10–40 g Powder and Granule Packaging

Learn how a dual-lane small pouch packing machine handles 10–40 g powder and fine-granule products, from roll feeding and measuring to sealing, cutting and counting.

For a small pouch packing project, the machine speed is usually the first number buyers notice.

For us, it is not the first thing we evaluate.

A small sachet weighing only a few grams creates a very different packaging challenge from a conventional 100 g or 500 g bag. The pouch is smaller, the sealing area is narrower, the filling tolerance has less physical space to work with, and the packaging material needs to remain stable through forming, filling and sealing.

The INNOV dual-lane small pouch packing machine is designed around this type of application. According to the current product specification, it integrates bag forming, measuring, filling, sealing, cutting and counting in one automatic process. The standard measuring range is 10–40 g, and two lanes operate simultaneously at approximately 40–50 bags/min per lane. 

Those numbers tell us the machine's intended working range.

They do not tell us whether a particular powder or granule will run well.

That still depends on the product.

The 10–40 g Range Is Only the Beginning of Machine Selection

Two products can both weigh 20 g and require very different filling conditions.

Twenty grams of a dense fine powder may occupy a relatively small volume.

Twenty grams of a lightweight granular material may require much more pouch volume.

The filling weight therefore cannot be separated from bulk density and flow characteristics.

When evaluating a new project, we prefer to know:

• actual product;
• target filling weight;
• product density or approximate filled volume;
• whether the material flows freely;
• whether it creates dust;
• whether it tends to stick or bridge.

The official machine range of 10–40 g is useful for confirming whether the project belongs in this machine category. It should not be interpreted as meaning every product between 10 and 40 g can use exactly the same filling configuration. The product page itself states that filling specifications can be customized according to product characteristics and target sachet weight. 

That is an important distinction.

A real machine recommendation comes from the material, not only the number on the weighing scale.

Why Dual-Lane Production Is More Than Two Filling Nozzles

The machine uses a double-lane structure.

The obvious benefit is output: two sachets can be produced at the same time.

But a reliable dual-lane machine needs more than two product paths.

Both lanes must remain synchronized through:

forming → measuring → filling → sealing → cutting → counting

If the material on one lane does not track correctly, the machine may still continue running, but the finished pouch can gradually move away from the intended shape or sealing position.

For this reason, when checking a dual-lane machine, we pay attention to both sides independently.

Does Lane 1 form the same way as Lane 2?

Are both pouch edges stable?

Is one filling path producing more dust than the other?

Is the cutting position consistent on both sides?

A dual-lane machine should be evaluated as one synchronized production system rather than two independent machines inside the same cabinet.

Bag Length Is Adjustable; Bag Width Is Not the Same Type of Adjustment

This is one specification that should be explained clearly to buyers.

The machine supports:

Bag Length: 28–40 mm — adjustable
Bag Width: 10–20 mm — fixed value according to configuration

The official product page makes this distinction explicitly. 

This matters during quotation.

A buyer may see “10–20 mm width” and assume the operator can freely change from 10 mm to 15 mm to 20 mm through the touchscreen.

That is not the same as the adjustable length specification.

The required pouch width should therefore be confirmed before the machine configuration is finalized.

Bag length provides more flexibility within the listed range.

Width should be treated as part of the machine setup.

This is exactly the type of technical detail that should be clarified before ordering rather than discovered after delivery.

Pouch Size Should Be Selected From the Actual Filling Volume

The smallest possible pouch is not automatically the best pouch.

If the product fills most of the internal volume, very little clean space remains around the sealing area.

This becomes particularly important with fine powder.

A fuller pouch can increase the chance that powder reaches the upper area before sealing.

The correct pouch size therefore needs to balance:

product weight + bulk density + required pouch appearance + clean sealing area

This is one reason we prefer to work from the customer's real sample.

A customer may tell us:

“I need a 15 g pouch.”

That does not yet tell us whether a 15 mm or 20 mm configured width is more practical.

We need to see the product volume.

For B2B packaging projects, designing the package only from a drawing can create unnecessary problems later.

Roll Material Has to Work With the Forming and Sealing Process

The listed machine specification supports a maximum film width of 220 mm and roll-film thickness of 0.05–0.10 mm. 

Your machine materials show soft non-woven/filter-type pouch material and ultrasonic sealing.

This means the roll material is not simply consumable packaging.

It becomes part of the machine process.

The material needs to:

feed smoothly,

maintain the required position,

form consistently,

respond correctly during sealing,

and cut cleanly.

Two roll materials can both be 0.08 mm thick and still behave differently.

The fiber structure, softness and surface construction may differ.

For this reason, we do not recommend confirming compatibility from thickness alone.

If a customer already has a local roll supplier, sending the actual material for testing is much more useful than only sending the specification.

Why Fine Powder Deserves a Real Machine Test

Fine powder is often more demanding than buyers expect.

The machine can measure and fill the product, but the real question is how the powder behaves while the pouch is being produced.

A dusty powder can move upward.

A sticky powder may remain in the filling path.

A product with inconsistent flow may require different dosing conditions.

If powder reaches the future sealing zone, sealing quality can be affected even when the sealing mechanism itself is working correctly.

This is why we do not separate “filling” and “sealing” completely during testing.

When there is a sealing problem, the filling condition should also be checked.

Counting Is Important When the Pouch Machine Connects to a Downstream Line

The current product page specifically states that counting is integrated into the automatic process. 

This becomes particularly useful when the finished small pouches are not the final retail product.

For example, if several pouches later need to be placed into one container, the production system needs to know how many pouches are available and how many belong in each downstream package.

The exact downstream method depends on the final project, but counting capability makes it easier to design the next stage around defined quantities rather than uncontrolled pouch accumulation.

This is where a standalone pouch machine begins to become part of a complete packaging line.

Do Not Select the Machine Only From 40–50 Bags/Min

The listed speed is 40–50 bags/min per lane. 

This is an important capacity reference.

But it should not be treated as a guaranteed working speed for every product, every roll material and every pouch size.

For real production, the useful speed is the speed at which:

• filling remains stable;
• both lanes remain synchronized;
• pouch formation remains correct;
• sealing remains consistent;
• cutting stays in position;
• counting remains reliable.

That is more valuable than reaching a maximum number for a short demonstration.

For a new project, we would rather know your product and target pouch first, then confirm the practical machine setup.

That is the difference between choosing a packing machine from a catalog and configuring one for actual production.
