Application-led filling & packing systems
Build the right line around the product—not the brochure.
Plan filling, closing, labelling and end-of-line equipment around how the product behaves, how it is packed and the rate the line must sustain.
Representative trials and a defined acceptance test come before final specification.

01 · Start with the customer pack
Packaging format determines the line architecture.
Choose the intended pack before the machine. Opening size, stability, sealing land, closure and decoration all affect how the product can be presented, filled, closed and inspected.
Rigid pack
Jars & bottles
Headspace, nozzle clearance, twist-off or screw closing, vacuum and label presentation.
Explore the route →
Wide-mouth pack
Pots & tubs
Positive support, clean flanges, foil or film sealing, snap lids and top labelling.
Explore the route →
Pre-formed flexible pack
Pouches
Reliable opening, bag support, seal-zone protection and controlled discharge.
Explore the route →
Rollstock pack
Sachets & VFFS
Film tracking, registered dosing, seal timing, cutting and variable coding.
Explore the route →02 · Think in connected stages
A line is more than a collection of machines.
Each hand-off must preserve container control, product condition and pack quality. The slowest or least reliable stage defines sustained output.

Design rule
Specify an acceptance criterion at every transfer—not only a cycle time.

03 · Product behaviour01 02 03 04
The difficult part is rarely the nominal fill volume.
Two products sold in the same jar can need entirely different pumps, valves, nozzles and cleaning routines. Define the full expected range—not the easiest batch.
Viscosity & temperature
Measure the thinnest and thickest conditions at the nozzle, not only in the kettle.
Pieces, seeds & fibres
Size the complete product path around the largest firm inclusion and the risk of bridging.
Distribution & suspension
Agitation and gentle recirculation may be needed to maintain a repeatable solids ratio.
Cut-off & presentation
Drip, stringing, tailing and splashing affect seal cleanliness and retail appearance.
04 · Choose the thermal route
Hot fill or cold fill changes the whole operating route.
Temperature affects product flow, microbiological control, pack compatibility, closure performance, operator safety and the time available before labelling or packing.
Control heat from vessel to closure.
Define the validated temperature and time window, then minimise uncontrolled heat loss through hoses, valves and waiting time.
- Heated or insulated holding tank
- Agitation appropriate to the product
- Guarding, splash control and PPE
- Closure, dwell and cooling verification
Separate hygiene from temperature.
Cold filling may improve pack and product handling, but it needs a defined hygiene, preservation or post-fill process rather than assumptions.
- Validated cleaning and hygiene route
- Product stability and hold-time control
- Vacuum capping where appropriate
- Alternative pasteurisation options
05 · Size for sustained demand
Calculate a planning rateMatch automation to weekly demand and operating reality.
<500packs / week
Desktop
Manual presentation with bench-scale filling or closing.
500–2kpacks / weekCompact
A small production cell with assisted handling.
2k–10kpacks / weekTwo-head
Coordinated conveyor stages and repeatable output.
10k+packs / weekMulti-head
Automatic container, closure and line-control systems.
Planning bands are starting points only. Model changeovers, cleaning, warm-up, replenishment, inspection, rejects and operator tasks.
06 · Equipment after evidence
Explore machine types only after the operating window is clear.
These first-party Lancing examples illustrate possible equipment categories. Final selection depends on product and pack trials, utilities, clean-down, footprint and sustained output.

Ask what the complete line must prove, not which machine has the fastest headline speed.
Use the equipment selector →07 · Packaging materials
Source packaging around a controlled specification.
Machine trials should use representative commercial packs, not approximate samples. StockPack can support the packaging route once dimensions, materials, tolerances and artwork are defined.
- Jars, bottles, pots and tubs
- Lids, closures and tamper-evident components
- Labels, sleeves and coding consumables
- Pouches, sachets and flexible materials
A better engineering brief01 02 03
Bring evidence—not assumptions—to the equipment review.
Representative samples and a defined acceptance test shorten selection, improve trials and reduce late-stage compromises.
Product
Full operating range, largest inclusions, temperature and cleaning expectations.
Pack & closure
Commercial samples, drawings, tolerances, sealing surfaces and opening evidence.
Output & site
Sustained demand, shifts, operators, utilities, footprint and future growth.
Practical questions
Answers before equipment selection.
Use these as briefing prompts, then confirm the route with representative product and pack trials.
It depends on viscosity, fill temperature, particle size and shape, volume, opening, cleaning and output. Particulate-rich products need generous passages and trials with the largest representative pieces.
No. The route depends on incoming container condition, product process, fill temperature and the validated hygiene or thermal method. Define the required outcome before selecting preparation equipment.
Hot filling may support flowability, a validated thermal process or closure vacuum formation. The actual temperature window, timing, pack compatibility and safety controls must be specified.
Potentially, if the complete product path handles both operating windows. Trial the pump, valves, hoses, nozzle, cut-off, cleaning and changeover with representative product.
Start with sustained weekly demand, available hours, operator tasks and growth. Desktop, compact, two-head and multi-head bands are planning starting points, not guaranteed capacities.
StockPack can support jars, lids, labels, sachets, squeeze bottles, tubes, pouches and other packaging materials once the commercial specification is defined.
