Compare liquid sachet filling and sealing routes for short runs and repeat production. Define the dose, film, changeovers and checks to discuss with Lancing.
Compare a liquid sachet filling solution as a combined dosing, forming and sealing process. The trial needs to show both the liquid quantity delivered and an acceptable finished sachet; a correct dose alone does not show that the seal area stayed clear.
Give Lancing the liquid at its intended filling condition, dose range and production film. Use the specification checklist to distinguish confirmed requirements from questions that need a trial.
For short runs and frequent changes, compare a simpler or semi-automatic setup using the time to clean, change format and release the first acceptable packs. For repeat production, also test how the filler receives liquid and how finished sachets reach the next stage. Compare accepted packs and rejects under the same conditions.
Discuss your application
Record filling temperature, flow behaviour, particles, foaming and settling, together with minimum and maximum doses. Pair each liquid with its intended sachet dimensions and film rather than treating the product and packaging as separate selections.
Compare product delivery and cut-off within the proposed forming and sealing cycle. Retain individual fill results and failed packs so drips, strings, splashes or seal contamination are not hidden by an average dose result.
Compare the complete production pattern: product supply and replenishment, accepted sachets, rejected film and liquid loss, cleaning, drain-down and first-off release after a change. Include the site interfaces and access needed for the agreed operating method.
Agree the quantity, seal, leak, appearance and code checks for the intended pack. Define how failed or uncertain sachets will be identified and kept out of accepted output, including the agreed response after an interruption.
Typical support: line concept, trials, filling or packaging equipment, integration and handover.
| Approach | Often suitable when | Watch for |
|---|---|---|
| Sachet Liquid Fillers | You need a dedicated solution for a clearly defined duty, product or part range and line interface. | The selected method must be trialled with representative product and packaging. |
| Semi-Automatic Equipment for Lower-Volume or High-Changeover Work | Your volumes, product mix or operator judgement make a simpler route more practical. | Check ergonomics, consistency and safe access before choosing the lower-complexity option. |
| Fully Automatic Line Integration where Repeatable Container Flow and Rate Justify It | Your surrounding process is stable enough for a broader automated solution to add value. | Allow for line connections, fault recovery and maintenance as well as the headline equipment. |
