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

Open-mouth bag weigh filling
Fill open-mouth bags by weight using bag support, clamping, weighing and sealing routes matched to the product.
Planning the right weigh filling route
Open-mouth bag filling is common for larger dry-product packs and semi-automatic bagging lines. The bag must be supported and held correctly while product is dosed.
The filling route may use gross weighing into the bag or a net weigh system that discharges a prepared dose. The choice depends on target weight, speed and operator involvement.
Dust, settling, bag stability and sealing should be considered at the start of the project.
Key buying checks
- Confirm bag size, material and mouth width.
- Decide gross weigh or net weigh route.
- Check dust and settling before sealing.
- Plan filled bag movement after release.
Routes to compare
Machine options to shortlist.
Open-mouth bagging projects should be planned around operator handling and bag stability.
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 open-mouth bag weigh filling?
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 open-mouth bag weigh filling?
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.
