Automatic filling machine news
30+ years of technology accumulation, is your reliable choice
A bulk bag filling machine is industrial equipment that automatically fills FIBC bags, also called big bags or jumbo bags, with materials such as cement, sand, fertilizer, grain, powder, and granules, using digital weighing sensors to reach an accuracy of around ±0.2 percent while reducing dust, labor, and product waste. GLZON builds this type of FIBC bulk bag filling machine to help factories in agriculture, construction, and chemical industries pack faster, weigh more precisely, and keep workers safe from repetitive manual lifting.
Many factories still rely on manual or semi automatic bagging machine setups. This approach feels affordable at first, but it creates hidden costs that grow every day.
A precision built big bag packing machine solves each of these problems directly.

The GLZON FIBC bulk bag filling machine uses a digital weighing system with smart sensors that monitor bag weight in real time. The filling speed is controlled in two stages, fast at the start and slow near the target weight, so the system reaches a final accuracy of approximately ±0.2 percent regardless of whether the material is a fine powder or heavy granulate.
The full filling cycle works in three steps:
This automated workflow allows one operator to do the work that would normally require two or three people, cutting labor costs while increasing daily output.
We built our machines to solve your problems. This table shows how our features help your business.
| Feature | Benefit | How We Do It |
| Precision Weighing (±0.2%) | Save Money: Keep the profit you used to lose. | We use smart sensors and a two-speed flow control to hit the exact weight. |
| Inflatable Seal Head | Safe & Clean: Stops dust that hurts workers and machines. | A rubber collar blows up to lock the bag spout tight. No dust escapes. |
| Automatic Shaking (Densification) | Cheaper Shipping: Makes stable, square bags that are easy to stack. | The machine shakes the bag while filling to remove air instantly. |
| Auto Loop Release | Work Faster: Removes the bag quickly so you can start again. | Automatic hooks let go of the bag straps when full. No manual work needed. |

A bulk bag filling machine is not limited to one industry. GLZON machines are configured for a wide range of bulk materials, including:
Construction materials
Agricultural materials
Chemical and industrial materials
Because flow characteristics differ between fine powder and heavy aggregate, GLZON adjusts nozzle design, flow control, and vibration settings for each material type to protect accuracy and prevent clogging or dust leakage.
Industrial bagging equipment needs to survive daily abrasive contact with rough sand, corrosive chemicals, and heavy cement dust. GLZON machines are constructed using:
This construction approach applies across the full GLZON lineup, from open mouth bag filling machines used for smaller pre made bags, up to large FIBC and ton bag filler systems built for 500 kg to 2,000 kg bulk bags.
For most mid to large scale operations handling cement, sand, fertilizer, grain, or industrial powders, a dedicated FIBC bulk bag filling machine pays for itself through three main channels:
GLZON backs this investment with a straightforward promise:
What is a bulk bag filling machine used for?
It is used to automatically fill FIBC bags, also known as big bags or jumbo bags, with bulk materials like cement, sand, fertilizer, grain, and industrial powders at high speed and accuracy.
How accurate is an FIBC bag filling machine?
GLZON machines achieve approximately ±0.2 percent weighing accuracy using digital sensors and two speed flow control.
What is the difference between an FIBC filler and an open mouth bag filling machine?
An FIBC filler is designed for large flexible bulk bags, typically 500 kg to 2,000 kg, while an open mouth bag filling machine handles smaller, pre made valve or open top bags.
Can one machine handle both powder and granular materials?
Yes. The system adjusts filling speed and vibration settings based on material flow characteristics, so it can switch between fine powders, granules, and heavier aggregates.
