Trial liquid detergent with the actual pouch: foam at startup and restart, nozzle drips, clean closures, compatibility, cleaning and completed-pack checks.
Use the actual liquid detergent and intended pouch to examine filling behaviour. Foam can change with formulation, temperature, agitation and product arrival at the nozzle. Observe startup, replenishment and restart after a pause as well as steady dosing. Check nozzle cut-off and contamination of the closure area before judging fill presentation and the completed pack.
Connect the pouch and closure requirements with the agreed trial and acceptance record. A water trial or a liquid refill-pouch result does not establish chemical compatibility or powder-detergent handling suitability.
Plan detergent pouch packing around your product, pack range, target output, cleaning needs and finished-pack checks. Discuss a practical line concept with Lancing using representative samples. Use this guide to resolve liquid detergent behaviour before it limits the final system.
Discuss your application
Provide the actual formulation, safety and technical data, target fill, filling temperature and product delivery arrangement. Record the intended pouch, laminate or fitment and observe how the detergent reaches the nozzle under normal production conditions.
Include normal and difficult filling conditions, startup, refilling and restart after a pause. Observe foam, drips, strings and splash during nozzle entry, dosing and withdrawal, and retain examples where detergent reaches the closure area.
Agree acceptable fill presentation and available settling time before closing or moving the pouch. Review wetted materials, seals, hoses and cleaning products with the responsible specialists. Include residual detergent and cleaning liquid in the changeover record, then assess the completed pack as well as the dose.
Record formulation, filling temperature, agitation and product arrival at the nozzle. Retain foam and nozzle cut-off observations from startup, refilling, steady production and restart after a pause.
Provide converted drawings and supplied examples covering openings, gussets and spouts or closures. Review nozzle access, pouch support, closing and discharge with the actual detergent.
State the target quantity and the agreed method for checking it on the intended pack. Review fill presentation, foam settling and the closure area alongside the dosing result; a nominal dose alone does not establish an accepted pack.
Record required accepted packs and the normal production pattern. Include rejects, product or pouch replenishment and restart in the output observation rather than counting filling strokes alone.
List fragrance, colour and formulation changes and permitted carryover. Map tanks, transfer lines, pumps, nozzles and drain points; identify residual detergent and cleaning liquid and record changeover until the next product is released.
Agree fill-quantity, seal or closure, external-cleanliness, coding and handling checks. Let the packaging owner define the pack-integrity method, and keep samples from startup, stable production and restart.
