Weigh filling lines by pack format: pouches, bags, jars and tubs.
Start with the finished pack when the container or pouch format is the main reason the machine route is uncertain.
Application planning
Start with your product and finished pack. Lancing compares product behaviour, target weight, pack handling and output so the machine shortlist is practical from the start.
A good recommendation balances product behaviour, target fill weight, pack handling, closure or seal method, throughput and how much operator involvement is acceptable.
Key planning points
- Pouches and bags may require opening, forming, sealing, coding and discharge control.
- Jars and tubs may need filling, settling, capping or lidding, induction sealing and labelling.
- Rigid containers and flexible packs need different handling, footprints and operator workflows.

| Pack format | Controls discharge height, filling mouth, closure, sealing and downstream equipment. | Pouch, bag, jar, tub, bottle, box or existing machine interface. |

FAQ
Pack-format weigh filling line questions.
Straight answers to help you choose the right filling route before requesting advice.
Should I choose the filler or pack format first?
Start with both together. Pack shape, closure, seal style and discharge method can change the practical filler route.
Can weigh fillers be integrated with capping and labelling?
Yes. Weigh filling can be supplied as a standalone station or considered as part of a wider line with closing, sealing, labelling and coding.
What pack details should I provide?
Send dimensions, material, fill opening, closure or seal style, target weight, output and any existing machine connection points.

Pack interface
The same weigher needs a different discharge and control plan for each pack.
Pack format changes the required support, product drop, timing and downstream inspection. Specify the finished pack, not only the fill weight.
| Pack format | Presentation and support | Weight-control considerations | Downstream scope |
|---|---|---|---|
| Open pouch or small bag | Operator hold, pouch support, foot-pedal discharge or an automatic pouch clamp. | Prevent product loss between the discharge chute and pack; confirm tare method and operator cycle. | Heat sealing, coding, seal cleaning and optional checkweighing. |
| Open-mouth bag | Bag clamp, height adjustment and stable support for the planned bag dimensions and filled weight. | Fast/coarse and slow/fine feed, in-flight product allowance and stable release at target. | Bag release, conveyor, sewing or heat sealing, flattening and weight verification. |
| Jar, tub or bottle | Repeatable centring below the chute, sufficient opening and stable container support. | Product bounce, dust, headspace, settling and clean cut-off affect both net weight and presentation. | Capping or lidding, induction sealing, coding, labelling and checkweighing. |
| VFFS bag | Timed discharge into a bag being formed from roll film. | Weigher ready/busy logic, discharge timing, drop height and product-in-seal control. | Jaw timing, film tracking, coding, finished-bag conveyor and checkweigher. |
Controls and acceptance points.
Agree whether the weigher waits for a pack-present signal, whether a missing pack inhibits discharge, how a reject or downstream stop is communicated and what happens to product already in the weigh hopper. For automatic lines, define ready, busy, discharge request, discharge complete, fault, low product, downstream available and emergency-stop interfaces.
A full-line acceptance run should use the intended product and packaging material. Record the net-weight distribution, pack damage, product loss, seal contamination, rejected packs and sustained output at the finished-pack point.
Specialist pack-format ownership.
Use Pouch Fillers for premade pouch opening and sealing, and Form Fill & Seal for roll-film VFFS machinery. This site retains ownership of the weighing method, target-weight evidence and interface between the weigher and those packing systems.
Pack-interface evidence
Pouch mouth, product drop and sealing hand-off decide whether the line works in practice.
The weigher can reach target correctly and still produce an unacceptable pack if the outlet, pouch presentation or downstream transfer loses product or contaminates the seal area.
| Pack route | Filling interface to define | Control and quality checks | Best owner for specialist detail |
|---|---|---|---|
| Operator-held premade pouch | Pouch opening width, gusset, zipper position, fill height, outlet diameter, foot-pedal timing and stable hand position. | Missing-pouch prevention, spillage, operator cycle, seal-area cleanliness and transfer to the sealer. | This site owns the weighing and discharge method; the separate sealer must be tested with the intended laminate. |
| Clamped open-mouth bag | Bag support, clamp position, gross or net weighing basis, dust containment and controlled release after filling. | Bag-present signal, clamp status, filled-bag support, conveyor release and safe handling of the load. | Bag-clamping weigh fillers. |
| Automatic premade pouch | Timed discharge into a pouch that has been fed, opened and positively detected. | Ready/busy handshake, pouch-open confirmation, no-pouch/no-fill logic, seal contamination and reject handling. | Pouch Fillers owns automatic premade-pouch handling. |
| VFFS bag from roll film | Former, bag cross-section, product drop, discharge timing and the clearance above the sealing jaws. | Bagger ready, discharge request, product-in-seal risk, coding, jaw timing and finished-bag inspection. | Form Fill & Seal owns the roll-film bagging machine. |
| Jar or tub | Container support, neck or opening size, settling, fill height and product bounce. | Container-present signal, tare control, indexing, product on the rim and the following lidding or capping operation. | This site owns weigh dosing; the closing equipment is specified as a separate line function. |
Use real packs to approve the discharge.
A supplied Lancing LU-DL5000D quotation for a 200 g pouch allowed for a provisional reduced-width stainless-steel discharge chute. The final width, length and flow geometry were explicitly left subject to product and pouch samples. That is the correct engineering sequence: the pouch mouth and product trajectory decide the outlet, not an isolated drawing.
- Check every pouch size. Measure the usable opening after accounting for zipper, gusset and seal margins.
- Confirm the filled shape. The pouch must support the dose without collapsing, blocking the outlet or placing product in the seal zone.
- Observe the product drop. Record bounce, dust, static, bridging and retained product at the narrowest point.
- Run the actual transfer. Include removal from the filler, orientation on the conveyor and presentation to the band sealer or automatic closing station.
- Recheck net weight after handling. Product lost between filler discharge and the finished pack must be visible in the acceptance record.
Pack samples to send.
- Production-quality pouches or containers for every required size.
- Dimensions, material or laminate and maximum usable opening.
- Seal, zipper, lid or closure requirement and code position.
- Smallest, normal and largest target weights.
- Photos or video of the current operator method and any existing conveyor or sealer.
- Acceptance rules for net weight, product loss, seal integrity and finished-pack output.
Buyer questions
Pouch and container interface questions.
Why are actual pouches needed before the outlet is finalised?
The nominal pouch width does not show the usable mouth after zipper, gusset, seal margin and the way an operator or machine holds it. Product size and trajectory also affect the outlet geometry.
Can a narrow pouch mouth be filled by a weigh filler?
Sometimes, using an appropriately designed removable outlet or chute. Suitability must be confirmed from the product, target volume, pouch opening and required clearance rather than assumed from weight range alone.
Should the sealer be included in the product trial?
Yes when finished sealed packs define acceptance. The trial should show product loss during transfer, seal-area contamination, laminate settings, code quality and sustained operator or line output.
When should the enquiry move to a specialist pouch or VFFS site?
Use the specialist pouch site when feeding, opening and sealing premade pouches is the primary requirement, and the form-fill-seal site when bags are made from roll film. WeighFillers.co.uk remains the owner of target-weight dosing and the weigher interface.
