In industrial production, it is not enough to simply transport powders, granules, and other bulk products within the production line. The final or semi-finished product must be packaged in a controlled manner for storage, shipment, or the next stage of production.
For high-volume bulk products, this process is typically carried out using Big Bags, also known as FIBCs.
However, filling a Big Bag is not simply a matter of pouring the product into the bag.
A poorly designed Big Bag filling system can result in:
- failure to meet the target weight,
- uneven filling of the bags,
- the risk of the bags tipping over on the pallet,
- inefficient use of bag volume,
- heavy dust emissions during filling,
- excessive aeration of the product,
- unnecessary operator intervention,
- low bags-per-hour capacity
.
In a modern FIBC filling line, however, it is not just the product flow that is considered;
weighing + bag preparation + leak-proof sealing + air venting + control of filling speed + compaction/deaeration + bag discharge
are all evaluated together.
Especially with powdered and lightweight bulk products, trapped air inside the bag can significantly affect the actual process capacity.
Therefore, the right question is not:
“How fast can we fill the Big Bag?” but rather, “How consistently and reproducibly can we fill the bag while accurately achieving the target weight?”
In this guide, we will examine Big Bag and FIBC filling systems in detail in terms of:
- filling principle,
- weighing,
- capacity,
- feeding,
- vibration,
- deaeration,
- dust control,
- automation,
- and integration with pneumatic and mechanical systems
.
What Is a Big Bag Filling System?
A Big Bag filling system is an industrial equipment system that ensures bulk products such as powders, granules, pellets, and similar materials are filled into FIBC bags in specified quantities, in a controlled manner, and in accordance with process conditions.
In English technical terminology:
- bulk bag filler
- bulk bag filling system
- FIBC filling machine
- FIBC filling station
are commonly used terms.
Depending on the application, a Big Bag filling station may consist of the following equipment:
- conveyor structure,
- bag suspension arms or hooks,
- filling head,
- bag mouth sealing system,
- load cell,
- weighing platform,
- product feed valve,
- rotary valve,
- screw feeder,
- vibration platform,
- bag inflation/pre-forming system,
- dust extraction connection,
- conveyor,
- PLC automation.
Therefore, a Big Bag filling system is not merely a filling spout on its own.
What is an FIBC?
FIBC is an acronym for “Flexible Intermediate Bulk Container.”
In Turkey, it is more commonly referred to as:
- Big Bag,
- jumbo bag,
- large bag
.
Depending on the product and manufacturer’s design, FIBC bags can have different:
- dimensions,
- carrying capacity,
- inlet opening,
- discharge opening,
- fabric,
- liner,
- and suspension type
characteristics.
Therefore, the actual geometry of the bag to be used must be known when designing the filling system.
How Does a Big Bag Filling System Work?
The basic filling cycle consists of several steps.
1. The empty Big Bag is connected to the system
The bag’s four lifting loops are placed on the carrier hooks.
The bag’s inlet is connected to the filling head.
2. The bag inlet is sealed
Some systems use an inflatable neck seal.
System manufacturers such as Spiroflow and Palamatic use inflatable neck seal solutions to secure the bag’s inlet to the filling nozzle and enhance dust control during filling.
3. The bag can be pre-formed
Depending on the application, air is injected into the bag to reduce wrinkles and open up the bag’s geometry.
This can help the product distribute more evenly to the corners of the bag. In Spiroflow and Flexicon systems, bag inflation/preforming is one of the options used for this purpose.
4. Filling begins
The product can be fed into the bag via:
- gravity,
- screw conveyor,
- rotary valve,
- pneumatic conveying,
- or other dosing equipment
.
5. The bag is weighed
A load cell or weighing platform monitors the actual fill quantity.
6. As the target weight is approached, the flow rate is reduced
Coarse filling is performed at high speed, followed by a more controlled final filling stage.
In Palamatic’s automatic FIBC filling systems, low-speed dosing is also used as the system approaches the final target weight following high-speed filling.
7. The bag is compacted or deflated
Vibration may be applied, particularly for products with low bulk density and those that are aerated.
8. Filling is completed
The bag opening is separated, the suspension straps are released, and the filled Big Bag is removed from the system using a:
- forklift,
- pallet truck,
- roller conveyor,
- or belt conveyor
.
Why Is Weighing Critical in Big Bag Filling?
One of the most important parameters on the filling line is:
the target bag weight.
For example, if the product is sold as:
1,000 kg/Big Bag
the actual fill weight must be controlled within process tolerances.
If the system consistently overfills:
- product giveaway,
- cost loss
occur.
If it underfills:
- shipping,
- commercial,
- and quality
issues may arise.
For this reason, weighing in filling systems is not merely an optional feature but a fundamental component of the process in most commercial applications.
How Is a Load Cell Used in Big Bag Filling?
A load cell converts mechanical load into an electrical measurement signal, enabling the bag’s weight to be monitored.
Two main architectures can be observed:
Base-weigh
The bag and a specific section of the filling system are weighed on a load cell or platform scale located at the bottom.
Hang-weigh
Weighing is performed while the bag is suspended.
Spiroflow’s technical filling guide explains that the hang-weigh system can reduce the dead load detected by the load cell, thereby enabling higher weighing resolution.
However, it is not possible to say that the hang-weigh system is more accurate in every case.
Actual accuracy is determined by:
- load cell capacity,
- mechanical construction,
- vibration,
- environmental loads,
- product flow,
- control algorithm,
- and calibration
combined.
What Is Gain-in-Weight Filling?
One of the common methods in big bag filling is gain-in-weight weighing.
In this system, the weight reading increases as product is added to the bag.
Control system:
- determines the starting weight,
- starts the filling process,
- monitors the weight increase,
- reduces the product flow rate as the target value is approached,
- and stops filling at the target weight.
This method is particularly suitable for applications where the bag is weighed directly on the system.
Why Are Coarse and Fine Feeding Methods Used in Big Bag Filling?
There is a fundamental speed–accuracy trade-off in weighing systems.
If you feed the product at a low rate throughout the entire filling process:
accuracy may increase, but cycle time will increase.
If you feed the product at a high flow rate throughout the entire filling process:
capacity increases, but the risk of exceeding the target weight may rise.
For this reason, a two-stage feeding process can be implemented:
Coarse Filling
The majority of the bag is filled at a high flow rate.
Fine Filling
As the target weight is approached, the flow rate is reduced.
For example, if the target is:
1,000 kg
the control system can theoretically use:
- high speed in the first section,
- low speed in the final section
.
Exact transition points must be determined based on the product flow and system dynamics.
What Is the Fall-In-Flight Effect?
One of the major sources of error in filling systems is the material still in motion within the line the moment the product feeding equipment is stopped.
Even if the valve closes;
- the chute,
- the auger outlet,
- the pipe,
- and the filling head
may still allow product to continue falling into the bag.
This amount can be considered:
fall-in-flight
.
Therefore, if the system stops feeding at the exact target weight, the actual final weight may exceed the target.
A good control algorithm must detect or calculate this amount of product.
What Affects Big Bag Filling Accuracy?
Product flowability
If the flow is irregular, dosing becomes difficult.
Feeding equipment
Screws, rotary valves, or gravity gates have different dynamics.
Load cell resolution
It affects the minimum change the weighing system can detect.
Mechanical vibration
It can distort the weighing signal.
Fall-in-flight
This is the amount of product that arrives after feeding has stopped.
Filling speed
Control may become more difficult at high speeds.
Automation
PLC filtering and cut-off algorithms are important.
How Is Big Bag Filling Capacity Calculated?
Filling capacity is not determined solely by the product feed rate.
A cycle may consist of the following:
empty bag placement + bag tying + filling + vibration + final weighing + bag separation + removal of the filled bag
Therefore, the theoretical capacity can be calculated as:
Bags/hour = 3,600 / Total cycle time (seconds)
Example Big Bag Filling Capacity Calculation
This is only an illustrative example.
Let’s assume:
- bag preparation: 50 seconds
- filling: 140 seconds
- compaction: performed simultaneously with filling
- final processing: 40 seconds
- removal of the filled bag: 40 seconds
Total:
270 seconds/bag
Theoretical capacity:
3,600 / 270 = 13.3 bags/hour
If each bag weighs:
1,000 kg
then the theoretical mass capacity is:
13.3 metric tons/hour
However, this value does not represent actual plant performance.
Operator time, product flow, forklift wait time, and process downtime can reduce capacity.
Why Is a Ton-Per-Hour Calculation Alone Insufficient?
For example, the upstream system:
20 t/h
may be able to supply product.
However, if the filling operator and bag-change cycle are limited to:
8 bags/hour
, the actual packaging capacity for 1-metric-ton bags will be approximately:
8 metric tons/hour
.
For this reason, a Big Bag filling line must be designed using a bottleneck analysis.
Why Don’t Big Bags Fill Evenly During Filling?
One common reason is the accumulation of product in the center.
Especially if the product has a high angle of repose, the corners of the bag may not fill sufficiently.
As a result, the bag may take on a:
- conical,
- piled-up at the top,
- unbalanced
shape.
This situation can:
- affect pallet stability,
- storage,
- stacking
performance.
What Is Big Bag Pre-Forming?
It is the process of inflating the bag with air before filling.
The purpose is:
- to separate the bag walls,
- to reduce wrinkles,
- to open up the corners of the bag,
- and to facilitate a more homogeneous distribution of the product.
It is noted that in Spiroflow’s FIBC filler designs, pre-inflating the bag with air can also be used to improve the bag’s shape.
What Is Densification?
Some products contain too much air when they enter the bag.
In particular:
- fine powder,
- low bulk density,
- and products transported via pneumatic conveying
can create a loose structure inside the bag.
Densification is the process of reducing the voids between product particles and removing trapped air.
For this purpose,
- a vibration platform,
- a conical vibration system,
- or compaction
can be used.
Spiroflow and Palamatic note that, particularly with aerated powders, vibration/deaeration helps ensure the bag is filled more compactly and stably.
Why Is Vibration Used in Big Bag Filling?
The purpose of vibration is not merely to “shake the bag.”
When applied correctly, it can:
- help remove trapped air,
- allow the product to settle into the corners of the bag,
- stabilize the bulk density during filling,
- and help the bottom of the bag form more evenly.
However, not every product responds the same way to vibration.
In some products, excessive vibration can cause segregation, product damage, or compaction.
In some products, excessive vibration can cause:
- segregation,
- product damage,
- and compaction.
Should Vibration Be Applied After Filling or During Filling?
Two methods can be used.
Post-filling
The bag is compacted after it reaches the target weight.
The disadvantage is that it extends the cycle time.
During filling
Vibration is integrated into the filling cycle at specific intervals.
This allows filling and densification to proceed in parallel.
Palamatic’s automatic systems provide an example where the vibration table is operated intermittently during the filling cycle.
Why Is Deaeration Critical?
For example, if a product has a bulk density of:
400 kg/m³
but increases to:
600 kg/m³
after settling, the volume occupied by the same weight within the bag changes significantly.
For 1,000 kg of product:
400 kg/m³ → 2.5 m³
600 kg/m³ → 1.67 m³
This is merely a mathematical example.
Actual product values must be tested.
This difference illustrates why proper deaeration can be critical for bag volume and logistics.
Why Does Dust Form During Big Bag Filling?
When product enters the bag, the air inside the bag must be displaced.
Especially when filling with dusty products at high flow rates, this air:
- carries product particles upward,
- which can lead to
dust escaping from the filling spout.
Therefore, the filling head must be designed to accommodate both:
product inlet
and:
controlled exhaust of the displaced air
.
How Is Dust-Free Big Bag Filling Achieved?
The basic approach is:
leak-proof bag connection + air venting + dust extraction system
.
Spiroflow’s commercial designs utilize twin-tube filling heads, where the product flows from the central channel into the bag, and the displaced air containing dust is directed to the dust collection system via a separate external channel.
Similarly, Flexicon explains that by connecting the filling ports to the dust collection system, the displaced air and dust can be removed from the environment.
Why Is the Filling Head Important?
The filling head’s function is not merely to direct the product into the bag.
It may also perform tasks such as:
- holding the bag opening in place,
- creating a seal,
- venting displaced air,
- and providing dust extraction.
For this reason, filling with a simple open pipe may not be sufficient for dust-containing products in modern industrial processes.
How Does an Inflatable Neck Seal Work?
The bag’s inlet opening is inserted into the filling tube.
The pneumatic seal is inflated to create contact between the bag opening and the filling head.
The objective is:
- to prevent the bag from shifting out of place during filling,
- and to reduce dust escape.
These types of inflatable seal systems are used as standard or optional equipment in many modern FIBC filler designs.
How Is Product Fed During Big Bag Filling?
Product can be delivered to the filling station using various pieces of equipment.
Gravity
This is one of the simplest solutions if the silo is located above the filling station.
Rotary valve
It can help control the product flow rate.
Screw Conveyor
It can be used especially in processes requiring controlled and variable-speed feeding.
Pneumatic Conveying
Product can be transferred from a remote production line to the Big Bag system.
Vacuum Conveyor
It can be considered for smaller-capacity or sensitive transfer applications.
Filling a Big Bag from a Silo
This is one of the most common processes:
Silo → Valve/Feeder → Big Bag Filling Station
If the product at the bottom of the silo flows freely, a two-stage gate or control valve can be used.
However, if the product flow is difficult;
- a rotary valve,
- screw feeder
or similar controlled equipment may be required.
Big Bag Filling via Pneumatic Conveying
If the product exiting the production line is not directly above the filling station, a pneumatic system can be used.
Example:
Process → Pneumatic Conveying → Receiver → Weighing/Filling → Big Bag
In Flexicon’s industrial system examples, there are designs where a pneumatic conveyor transfers the product to a receiver equipped with a load cell, and the pre-weighed batch is then discharged into the Big Bag at high speed.
This approach separates the filling and weighing processes, enabling cycle optimization on high-capacity lines.
What Are the Benefits of Using a Pre-Weighing Hopper?
Let’s consider two different systems.
System A
The Big Bag is weighed while being filled directly.
System B
The product is first brought to the target weight in a separate weighing hopper and then quickly discharged into the Big Bag.
In the second approach, the next batch can be prepared while the bag is being changed.
This can reduce cycle time in high-capacity automated lines.
Flexicon’s high-capacity systems also utilize the dual pre-weigh hopper approach for this purpose.
Big Bag Filling System Automation
The level of automation may vary depending on the application.
Manual
The operator:
- attaches the bag,
- controls the valve,
- stops the filling.
Semi-automatic
The operator prepares the bag; the system:
- weighs,
- fills,
- and performs coarse/fine feeding
automatically.
Fully automatic
The system can also be equipped with:
- a pallet dispenser,
- bag handling,
- automatic loop release,
- a conveyor,
- and downstream palletizing.
In
In Palamatic’s high-capacity systems, functions such as automatic bag release, pallet handling, weighing, and conveyor discharge can be integrated into a single cycle.
How Can Bag Stability Be Improved During Big Bag Filling?
For a stable bag:
- proper opening of the bag,
- proper formation of the base,
- distribution of the product to the corners of the bag,
- reduction of trapped air,
- and controlled vibration
are important.
An unstable bag:
- during forklift transport,
- during storage,
- and during stacking
can pose a risk.
Why Is Bag Height Adjustment Important?
FIBC bags come in various sizes.
If the filling station is not suitable for the bag height:
- the bag may not stretch sufficiently,
- the base may not form properly,
- and the bag slings may be subjected to unnecessary stress.
For this reason, in some systems, the filling head or sling arms are designed to be adjustable.
Product Breakage During Big Bag Filling
For granular or fragile products, a high free-fall distance can cause product damage.
To minimize this:
- bringing the filling head closer to the bag,
- controlled adjustment of the bag level,
- low-speed feeding
are design options that can be considered.
Spiroflow uses “rise and fall” filling designs for fragile products to reduce the product drop height.
Risk of Segregation in Big Bag Filling
In blended products, differences in:
- particle size,
- density,
- and
shape
can cause segregation during filling.
In particular, long free-fall distances and excessive vibration can increase this risk in some blends.
Therefore, when filling a Big Bag with a blended product, not only the bag weight but also mixture homogeneity should be a quality criterion.
When Should Stainless Steel Be Used in a Big Bag Filling System?
Stainless steel may be preferred, particularly in:
- food,
- chemical,
- corrosive product,
- and processes requiring washing
applications.
However, a stainless steel construction alone does not guarantee hygienic design.
Additionally:
- welds,
- surfaces,
- gaskets,
- dead zones,
- and access for cleaning
must also be evaluated.
Big Bag Filling in Food Applications
In food processes:
- product-contact materials,
- gasket compatibility,
- cross-contamination,
- cleanability,
- and foreign material control
must be considered.
If a specific hygiene standard or certification is claimed for a product, this must be verified through the equipment’s technical documentation.
Big Bag Filling for Chemical Powders
In chemical processes, the following should also be evaluated:
- material compatibility,
- corrosive effects,
- toxicity,
- sealed connections,
- operator exposure
may also be evaluated.
Some processes may require a higher level of containment.
Big Bag Filling for Explosive Powders
Some powders can create an explosive atmosphere under certain conditions.
In this case:
- the product’s explosive properties,
- facility zone classification,
- static electricity,
- FIBC type,
- grounding,
- equipment suitability,
- and dust extraction system
must be the subject of a separate process safety study.
A standard Big Bag filling machine is not automatically ATEX-compliant.
Such statements should only be used in conjunction with the equipment’s actual certification and documentation.
Static Electricity in Big Bag Filling
The movement of the product through the:
bag can generate electrostatic charges.
Especially in flammable dust processes:
- equipment bonding,
- grounding,
- and
selection of an appropriate FIBC
are critical.
This issue should be addressed by experts as part of the facility’s risk assessment.
Big Bag Filling or Big Bag Discharging?
Although these two systems may appear to be opposite processes, their engineering objectives are different.
Criterion Big Bag Filling Big Bag Discharging
Product movement From process to bag From bag to process
Primary objective Accurate weight and packaging Controlled product discharge
Weighing Very important Application-dependent
Densification May be important Generally not
Bag agitation Generally not required Important for non-free-flowing products
Dust control Filling air is controlled Dust from bag opening/discharge
Next step Storage/shipping Transportation/production
Since the existing content on Big Bag Discharge Systems at MASTRON covers the discharge side in detail, this page should provide only a brief comparison and include an internal link to the existing guide.
Big Bag Filling or Bag Filling?
In general:
Big Bags
- may be advantageous for high-volume bulk products,
- fewer packaging units,
- and forklift logistics.
Small bags
may be more suitable for retail or smaller batches,
- manual handling,
- and smaller shipping units.
- Production capacity and logistics model are key factors in the selection process.
12 Common Mistakes in Big Bag Filling
1. Selecting a system based solely on bag capacity
Just because a bag holds 1 metric ton does not mean the system has a capacity of 1 metric ton per hour.
2. Selecting a load cell independently of the mechanical design
Dead load and vibration can affect measurements.
3. Using a single filling speed
This can increase the risk of overshooting the target weight.
4. Failing to account for the “fall-in-flight” effect
Product flow may continue after feeding is stopped.
5. Ignoring the product’s aeration behavior
Bag volume may be used inefficiently.
6. Treating densification separately from filling
Cycle time may increase.
7. Adding dust extraction as an afterthought
The filling head must be designed with this in mind from the start.
8. Assuming bag dimensions are standard
FIBC geometries may vary.
9. Neglecting product breakage
A long free fall can cause problems.
10. Failing to account for forklift cycle time
This can be the actual bottleneck of the packaging line.
11. Failing to match upstream system capacity with the filling system
Product backlog or insufficient feeding may occur.
12. Assuming weighing accuracy is the same for all products
Actual accuracy depends on product and system conditions.

Frequently Asked Questions
What is a Big Bag filling system?
A Big Bag filling system is an industrial packaging system that enables powdered or granular bulk products to be filled into FIBC bags in controlled quantities and weighed according to the application.
Are FIBC and Big Bag the same thing?
In practical industrial use, “Big Bag” is one of the commonly used names for FIBC bags.
How does a Big Bag filling system measure weight?
The weight of the product added to the bag can be monitored using a load cell or platform scale. As the system approaches the target weight, it can reduce the filling rate and stop the feed.
How is Big Bag filling capacity calculated?
Total cycle time is calculated by evaluating not only the product flow rate but also the times required for bag tying, filling, densification, bag removal, and logistics.
Why is vibration used in Big Bag filling?
It can help compact the product—especially in aerated powders—reduce the air inside the bag, and make the bag more stable.
Why does dust escape during Big Bag filling?
As the product enters the bag, it pushes the air inside the bag outward. This air can carry fine particles with it.
How is dust reduced during Big Bag filling?
The bag opening can be sealed airtight to the filling head, and the displaced air can be directed into a dust collection system.
What is pre-forming in Big Bag filling?
It is the process of inflating the empty bag with air prior to filling to reduce wrinkles and prepare the bag’s geometry.
Why are coarse and fine feeding stages used in Big Bag filling?
Coarse feeding shortens the cycle time, while fine feeding—performed when the weight is close to the target—helps reduce the risk of overshoot.
Can a pneumatic conveying system be connected to a Big Bag filling system?
Yes. After the product is conveyed via a pneumatic line to a receiver or pre-weighing hopper, it can be transferred to the Big Bag filling system.
Conclusion: How to Design the Right Big Bag Filling System?
Big Bag filling systems are not merely machines that pour product into a large bag.
True process performance:
product behavior + bag geometry + feeding system + load cell + control algorithm + filling speed + deaeration + dust extraction + logistics
emerges when these factors are evaluated together.
Especially with light and airy powdered products, simply reaching the target weight is not sufficient.
The bag must:
- use its volume efficiently,
- form a stable geometric shape,
- and remain stable during forklift handling and storage processes
.
Similarly, when aiming for high capacity, simply increasing the upstream feed rate does not yield results.
Bag changeover time, the removal of filled bags from the line, and the weighing cycle are also part of the system’s capacity.
Therefore, the right Big Bag filling system is not simply the equipment that delivers product the fastest; it is a system that consistently achieves the target weight, fills the product in a controlled manner, and delivers a stable FIBC to the subsequent logistics process.
