Linear weigh fillers
Good for moderate outputs, multiple products and controlled dry product dosing.

Net weigh fillers and weigh hopper systems
Compare net weigh filling systems for dry products before choosing a bag, pouch, jar or tub filling route.
Planning the right weigh filling route
A net weigh filler weighs product before discharge into the pack. This can help improve cycle control because the next dose can be prepared while the filled pack is moved away or closed.
Net weigh routes are often used for granules, seeds, small parts, pet food, coffee and many dry ingredients. They may be configured with vibratory trays, belt feeders, weigh buckets or multi-hopper arrangements.
The suitability of a net weigh filler depends on product flow, target weight, fill opening size, headroom and whether the line is operator fed or fully automatic.
Key buying checks
- Confirm whether weighing happens before or inside the pack.
- Check discharge opening against the pack mouth.
- Review product drop height for fragile goods.
- Allow for feeding and refill time between cycles.
Routes to compare
Machine options to shortlist.
Net weigh systems can suit many dry products where a prepared weighed dose is discharged into the pack.
Multihead weighers
Useful where speed, accuracy and product combination are central to the project.
View routeAuger fillers
Often compared for powders, fine ingredients and products that need screw dosing.
View routeVFFS weigh lines
For automatic bag forming, weighing, filling and sealing from film reels.

Questions before choosing a weigh filler.
Short answers for production teams comparing dry-product weighing and filling routes.
What information is needed for net weigh fillers and weigh hopper systems?
Useful details include the product name, bulk density if known, target fill weight, acceptable tolerance, pack format, output per minute or hour and whether the line must connect to feeding, sealing, capping, labelling or checkweighing equipment.
Which machine type is normally compared for net weigh fillers and weigh hopper systems?
Linear weighers, multihead weighers and auger fillers may all be considered depending on product flow, dose size and output target.
Can Lancing help with a complete line rather than a standalone filler?
Yes. Many projects involve product feed, weighing, filling, pack handling, sealing or closing and downstream checking. Sending the full pack route helps avoid choosing a filler that later becomes difficult to integrate.
Send the product, target weight, pack format and output target.
Lancing can advise whether a linear weigher, multihead weigher, auger filler, VFFS line or integrated route is the practical starting point.
