PAK-BM50 Belt Packing Machine
A belt-fed weighing, filling and closing solution for compatible powders, blends and bulk materials in 25–50 kg open-mouth bags.
Heavy-Bag Belt Feeding
Controlled 25–50 kg filling for varied material behavior
The PAK-BM50 uses belt feeding to transfer product steadily into the weighing and filling process. It is intended for compatible powders, blends and other bulk materials where a controlled feed path can support stable bagging. The standard specification combines weighing, filling and bag-closing integration with SS304 construction.
Material behavior determines the final machine configuration. PAKEWIN reviews bulk density, particle size, moisture, flowability, dust and segregation risk before confirming belt dimensions, feeding stages, bag support and dust-control interfaces.
Belt Feeding
Move suitable materials through fast and fine feeding stages with controlled belt transfer.
Line Integration
Connect bag sewing, conveying, coding, inspection and palletizing according to the project.
Operating Process
How the PAK-BM50 belt bagging cycle works
1. Material supply
The product enters the supply hopper from upstream storage or conveying. Hopper geometry and agitation requirements are selected for the actual material.
2. Belt feeding and weighing
The belt feeder transfers product through coarse and fine feeding stages. The weighing controller reduces the feed rate as the target weight approaches.
3. Bag placement and filling
An operator presents an open-mouth bag to the filling spout. The bag is supported and clamped before the weighed material is discharged.
4. Closing and downstream handling
The filled bag is conveyed to sewing or another compatible closure, then can continue to coding, inspection and pallet handling.

Application Engineering
Information required for belt feeder selection
Material characteristics
Provide the product name, bulk density, particle size distribution, moisture, temperature and flowability. Samples or videos can help identify bridging, sticking or dust concerns.
Accuracy and capacity
State the target bag weight, acceptable tolerance and required bags per hour. The relationship between speed and accuracy is confirmed during engineering and testing.
Bag and closing method
Provide bag material, dimensions, mouth width and closure method. Woven, paper and compatible plastic bags may need different supports, conveyors and closing equipment.
Complete packaging line
The system can be integrated with dynamic checkweighing, metal detection and robotic palletizing when suitable for the product and process.
Frequently Asked Questions
PAK-BM50 selection questions
What materials can the PAK-BM50 pack?
The PAK-BM50 is intended for compatible powders, blends and bulk materials that can be controlled by a belt-feeding system. Final suitability depends on bulk density, particle size, moisture, flowability, dust behavior and segregation risk.
What bag weights can the PAK-BM50 handle?
The specified packing range is 25–50 kg. The final operating range should be confirmed using the actual material, target accuracy, bag dimensions, bag-mouth construction and closing method.
What is the production capacity of the PAK-BM50?
The stated capacity is up to 200 bags per hour. Actual output depends on target weight, material flow, feeding distance, operator handling, bag closing and downstream conveying.
When should a belt-fed packing machine be selected?
Belt feeding can be considered when a material needs a steady, controlled transfer path and is not best served by a simple gravity feed. Representative product testing is recommended before final configuration.
For smaller 5–25 kg flour and compatible powder bags, compare the PAK-BP25 powder packing machine.
