Sticky granules and tacky products in weigh filling
Compare practical ways to improve sticking or poor flow in dry-product filling.
Start with the product and pack.
Sticky granules and tacky products is usually caused by the relationship between the product, hopper, feeder and target dose. A filler that works well on one dry product may struggle when sticking or poor flow changes the flow into the weighing system.
The solution may be a different feeder, a modified hopper, slower feed control, product agitation, dust extraction, a checkweigher or a different packing layout. The most reliable route is chosen after looking at the product behaviour and the output target together.
Typical projects include dried fruit, coated sweets, tacky granules and oily pet treats. Lancing can compare the options before the line is priced, so the specification is based on the problem being solved rather than only the headline machine type.
Specification checks
- Describe when sticking or poor flow happens during filling, feeding, discharge or sealing.
- Confirm the target fill weight, required tolerance and current giveaway or reject level if known.
- Send photos or video of the product feeding and the pack being filled where possible.
- Decide whether the priority is consistent feed and discharge, higher speed, cleaner operation or less operator handling.

Questions before choosing a weigh filler.
Short answers for buyers comparing dry-product filling equipment.
Can a weigh filler help with sticking or poor flow?
Yes, if the weighing route, feeder and pack handling are selected around the product behaviour. Sometimes the feeder and hopper are more important than the weighing controller itself.
Do I need a completely new line?
Not always. Some projects can be improved with different feeding, discharge, checkweighing or operator handling. Other projects need a complete weigh-fill-seal route.
What should I send before asking for advice?
Send product details, target weight, tolerance, output, current problems and any photos or short videos that show the product flow.
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.
