01
Flow and bridging
Cohesive powders bridge and rat-hole in the hopper, so the auger runs short and the weight drops.
What we do · The agitator and hopper are chosen for how your powder flows.
Powder Packaging
Powder packaging starts with dosing. Our VP Series with an auger filler and our VGT quad-seal baggers are used for powders such as flour, milk powder and protein powder.
Packages: pillow and chain bags or quad-seal bags
Powder Packaging Challenges
Six points that decide whether a powder line runs well.
02
Bulk density changes
Powder settles and aerates, so the same auger turn delivers a different weight.
What we do · Auger dosing is checked against weight with your powder in the test.
03
Dust in the seal
Fine powder rising from the bag reaches the seal area and causes weak or leaking seals.
What we do · Every packaging test checks seal quality and powder in the seal area.
04
Dripping after the dose
Free-flowing powder keeps trickling from the auger outlet between doses.
What we do · An anti-leak outlet is matched to your powder.
05
Static
Static makes fine powder cling to the film and the forming tube.
What we do · Static elimination is an option on the VGT and is chosen with your film.
06
Air in the bag
Powder traps air, so bags puff up, sit badly and are hard to case.
What we do · Product settler and bag deflator options on the VGT are matched to your powder.
Recommended Packaging Route
Feeding and dosing are set for the powder first; the packaging machine follows from the package.
- 01
Powder Feeding
Screw feeder refills the auger hopper
- 02
Auger Filler
Doses the target weight
- 03
Packaging Machine
VP or VGT, chosen by the package
- 04
Inspection
Checkweighing and contaminant checks
- 05
Case Packing and Palletizing
Bags into cases, cases onto pallets
Product settler, static elimination and bag deflators are options on the VGT and are fitted to the project.
LINYOPACK machines
Modules Matched to the Product
Start from the package: each packaging machine below is labelled with the bags it makes. Dosing, inspection and end-of-line modules complete the line.
Packaging machines
VP Series Compact VFFS
Listed with an auger filler for powders. VP320, VP420 and VP520, 20–90 bags/min,* film up to 520 mm wide.
VGT Series Quad-Seal VFFS
Listed for milk and protein powders. Front panel up to 300 mm wide, up to 80 bags/min.* Product settler, static elimination and bag deflators as options.
*Machine maximum. Actual output depends on product, fill weight, bag size and film.
Around the packaging machine
Auger Filler
The auger, agitator and anti-leak outlet are chosen for how your powder flows, how dusty it is and the target weight. The dosing result is confirmed with your powder.
Inspection
Checkweighing, metal detection, combined units, or X-ray where the application calls for it. The method is chosen once the product and package are known.
Case Packing and Palletizing
Robotic case packing and palletizing, integrated around the finished bag, the case pattern, the case rate and the pallet pattern.
Define Sustainable Good Output
A powder line runs at the pace of its slowest stage: refilling the auger, dosing, bagging and sealing. We check each stage instead of quoting the bagger's top speed.
Required kg/h= Good bags per hour × Fill weight
We set the final line target from tests with your powder and agreed FAT conditions.

The machines, dosing, industry and full system behind this application.
Which LINYOPACK machines are used for powders?
The VP Series with an auger filler, and the VGT series for quad-seal bags of milk and protein powders.
When should I choose the VGT?
When you need quad-seal bags. The VGT lists milk and protein powders, with options such as product settler and static elimination.
What decides the auger set-up?
The powder's flow, bulk density and dust, the target dose, the refill method and the output you need.
How accurate is the auger dosing?
Accuracy depends on your powder and the auger set-up, so we confirm the weight result with your product in the test.
Can the VP line run 90 bags/min with powder?
20–90 bags/min is the VP machine range. A powder line also depends on refilling, auger dosing, bag, film and seal conditions.
Can the SVC260 pack powders?
The SVC260 is not a standard route for powders. For powder we use the VP Series or the VGT.
How is dust handled?
Dust extraction and any combustible-dust requirements are reviewed for each project. Tell us the powder and your site rules.
Can inspection, case packing and palletizing be added?
Yes. Checkweighing, metal detection, robotic case packing and palletizing can be integrated around the bag, the case and the pallet.
Start With Your Powder
Send the powder, target weight, bag format and required output. We will use them to define the dosing and packaging set-up and plan the test.
