Powder Granule Bag Making Filling Sealing
Powder/Granule VFFS Packaging Machine
The powder/granule VFFS packaging machine starts from roll film bag making, then uses auger, weighing or other dosing methods to complete filling, sealing and cutting. Powder dust, fragile granules, static electricity, bag mouth residue and feeding stability affect the solution. Dosing, dust removal, gas flushing, coding and downstream finishing are optional per project.

Factory equipment photos
Actual equipment photos from the factory. Confirm the final configuration with the containers, product, sample trials and agreed equipment scope.
See actual working conditions first
Same main machine, but dosing and filling still need to be designed separately per material
Please provide material, particle size and flowability, target weight, roll film and bag samples, dust requirements, target speed and feeding conditions.
Packaging material and process must match
Composite roll film suitable for vertical bag making and heat sealing; film width, thickness, friction, heat seal layer and print registration confirmed per sample; roll film unwinding, bag forming, longitudinal sealing, optional auger or weighing dosing, filling, cross sealing/cutting and bag discharge
Optional modules are not standard
Optional auger, combination scale or linear scale, feeding, dust removal, gas flushing, coding, inspection, rejection and conveying.
Parameters confirmed per project
Please provide material, particle size and flowability, target weight, roll film and bag samples, dust requirements, target speed and feeding conditions.

Information recommended before quotation
The more complete the samples, packaging materials and site information, the easier to determine equipment route, changeover scope and line interface.
Configuration reference
- Powder and granules are matched with auger, weighing or other suitable dosing methods respectively
- Filling tube, dust prevention and bag mouth cleaning are tested with actual materials
- Feeding, dust removal, gas flushing, coding and inspection are optional modules
- Dosing accuracy, bag length, sealing and actual speed are confirmed per material and film
Prepare for selection
- Powder or granule samples, particle size, flowability, dust, static and moisture absorption data
- Target weight per bag, allowable tolerance, granule integrity and feeding method
- Roll film and finished bag samples, bag width and length, heat seal layer and print registration
- Dust cleaning, target speed, power supply, air supply and downstream conveying requirements

Key Parameters
Capacity and Speed
Confirmed based on material dosing response, filling settling, bag length, bag mouth residue, cross seal dwell time and feeding continuity. Actual capacity is confirmed by project trials.
Automation Scope
Automatic roll film bag making, dosing interface and sealing/cutting; feeding, dust removal, gas flushing, coding, inspection and conveying are optional per project
Applicable Container or Packaging
Pillow bags or similar bag types made online from roll film; bag width, bag length, gusset and sealing form confirmed per finished product
Applicable Materials
Powder, fine granules or granular products; flowability, dust, static, moisture absorption, fragility and particle size must be specified
Packaging Materials and Consumables
Composite roll film suitable for vertical bag making and heat sealing; film width, thickness, friction, heat seal layer and print registration confirmed per sample
Basic Process
Roll film unwinding, bag forming, longitudinal sealing, optional auger or weighing dosing, filling, cross sealing/cutting and bag discharge
Tooling and Changeover
Adjust or replace dosing parts, hopper, filling tube, bag former, film path and sealing/cutting position per material and bag type
Power Supply, Air Supply and Layout
Confirm equipment dimensions, power supply, air supply, maintenance space and upstream/downstream interfaces based on dosing feeding, film drive, heat sealing/cutting, dust removal and optional inspection/conveying
Steps from sample confirmation to delivery
Record flowability, dust, static, moisture absorption, fragility and dosing performance.
Select dosing, hopper, refill, filling tube and dust prevention structure.
Check bag length, filling settling, bag mouth cleaning, cross seal and cutting.
Acceptance with agreed material, dosing, bag forming, sealing, cleaning and material change.
Common configuration routes
Compare powder auger, granule weighing and pre-made bag routes
Do not select from the machine name alone. Compare dust, particle integrity, dosing method, rollstock structure and bag format and confirm the boundary with actual samples.
Powder Auger Dosing
Suitable for powders requiring volumetric or auger control, focusing on dust and residue management.
Granule Weighing Dosing
Suitable for granules and small items, focusing on drop, speed and product integrity.
Pre-made Bag Pick and Place
For complex bag shapes or zipper bags, compare pre-made bag route; main machine structure differs.

Frequently Asked Questions
Can powder and granules share one dosing system?
In most cases, the dosing principle and filling structure differ. The main machine interface can be shared, but the dosing system must be selected or changed per material.
Will dust enter the cross seal and affect sealing?
It is possible. Control through filling rhythm, settling, dust extraction and bag mouth cleaning; related modules are decided based on material testing.
Send samples and requirements
Confirm samples, packaging materials and process first, then finalize configuration
Send actual product or pack samples, critical dimensions, dust, particle integrity, dosing method, rollstock structure and bag format, target cycle, layout and acceptance criteria. Photos, videos or drawings can be reviewed first.
