Record liquid and film combinations, finished sachet dimensions, artwork and the first packs to check after a product or format change.
For a liquid sachet project, define the production film and approved sachet design alongside the liquid and dose. Dimensions alone do not describe the forming and sealing task: reel details, registration where used, opening features and code position also belong in the brief.
List the actual liquid and film combinations and the intended change sequence. Use finished-pack acceptance checks for each agreed representative combination rather than assuming one successful pack proves the whole range.
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 container, bag or pack range before it limits the final system.

Record the film specification and reel details, sachet dimensions and approved artwork or drawing revision. Identify registration marks where used, the intended opening feature and code position so samples and trial results refer to the same pack.
List each intended liquid, dose and film combination, including the proposed sequence of format or product changes. Identify which combinations have been demonstrated and which still require a trial; a dimension range alone does not confirm suitability.
Show which settings, safeguards, maintenance tasks, decisions or required outcomes are affected by changes in container, bag or pack range.
List each liquid against the production film proposed for it. Include the filling temperature and identify combinations that still need a trial.
For each format, record the drawing or artwork revision, finished width and length, reel information, registration mark and intended opening feature.
Add the target quantity and unit for each liquid and pack combination. Record the permitted variation or mark it for agreement.
List the order in which products and formats normally run, the required accepted rate and which change most often interrupts production.
Describe what the operator changes, which liquid remains in the feed path and how the first usable packs are identified. Record lost liquid or film separately.
Retain representative first packs after the format change. Check the dose, seal, leak, print and opening against the agreed finish and record who releases the run.
