What evidence should be agreed before acceptance testing for sachet liquid fillers?
Accept a liquid sachet filling process against the agreed completed-pack results, not the delivered dose alone. Record individual quantity results together with seal and leak checks, appearance, code readability and the intended handling of rejected or uncertain packs.
Agree the methods and limits before the trial. The specification checklist connects those results to the liquid, film, production pattern and cleaning or change sequence.
Plan sachet liquid fillers 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 finished-pack checks and reject handling before it limits the final system.
Discuss your application
State the agreed quantity, seal, leak, appearance and code checks, their limits and the sampling record. Keep the liquid condition, film identity, operating state and any filling-position identity with each result and retained failed sample.
Cover start-up, stable production, replenishment and a planned pause and restart using representative liquid and film. Include the agreed product-change and first-off release sequence; distinguish accepted sachets from trial rejects, liquid loss and rejected film.
Separate a quantity failure from seal contamination or a leak when recording results. Agree what is held, checked or removed after an abnormal result and which first-off checks are needed before production resumes; do not infer the cause from one average value.
Record the batch, liquid temperature and the condition at the filling point. Note foaming, separation or particles if they occur during the run.
Label retained packs with the film and artwork revision, nominal sachet dimensions and the opening feature being tested.
Write down the stated unit, target, agreed limits and individual readings. Keep readings from different operating conditions separate.
For each agreed run, count saleable packs and rejected packs separately. Mark starts, replenishment, planned stops and restarts in the record.
Record the change or cleaning sequence and identify the first packs checked after restart. Name the person responsible for release against the agreed method.
Keep a failed sachet with its operating conditions. Record whether quantity, seal, leak, appearance or code failed, what was held and what needs checking again.
