How to choose a weigh filler for your product and pack format.
A practical buyer guide for dry-product producers comparing weigh filling machines, weight fillers, auger fillers and integrated bagging lines.
Decision order
- Product behaviourFlow, dust, fragility, density and bridging risk.
- Target fill and toleranceMinimum, maximum, giveaway limits and accuracy expectation.
- Pack formatOpening size, pack stability, seal, closure and finished presentation.
- Output and labourPacks per minute, operator loading, shift pattern and future volumes.
Do not start with the model number.
The safest route is to decide whether the process needs vibration-fed weighing, combination weighing, screw dosing or an integrated bagging line. The machine model should follow that decision, not lead it.
Use the links below when you are ready to compare linear weigh fillers, multihead weighers, auger fillers and VFFS lines in more detail.

Use this table to decide which route is worth discussing for your product and pack.
| Need | First route to compare | Reason | Next page |
|---|---|---|---|
| Free-flowing seeds, beans, granules or small parts | Linear weigh filler | Simple weight-controlled dosing for many consistent products. | Linear route |
| Fast packing of irregular snacks or pet food | Multihead combination weigher | Combination weighing can improve speed and target-weight accuracy. | Multihead route |
| Fine powders, spices or dry blends | Auger filler | Screw dosing gives more controlled delivery for many powder behaviours. | Auger route |
| Bagging from roll film | VFFS weigh filling line | The line forms the bag, doses product and seals the pack in one process. | VFFS route |
Choosing a weigh filler.
Quick answers to common early-stage specification questions.
What information does a supplier need to recommend a weigh filler?
A useful enquiry includes product type, flow behaviour, target fill weight, tolerance, pack format, target output, available space and any downstream equipment.
Is a weigh filler the same as a volumetric filler?
No. A weigh filler controls the dose by weight, while volumetric filling controls the dose by volume. Product density variation can make this distinction important.
Can one weigh filler handle many products?
Often a machine can handle a range, but change parts, cleaning, feed behaviour, accuracy and speed expectations decide how practical that range is.
Send the product, target weight, pack format and output target.
That gives Lancing enough information to compare a linear weigher, multihead weigher, auger filler or integrated bagging line.
