A pouch filling changeover is validated when the next product and pack are set safely, first-off pouches meet the agreed checks and the setup can be repeated from a controlled record.
A changeover may alter pouch or film handling, dosing, product-contact parts, sealing, coding, inspection and line controls. The approval sequence should show that the new setup produces good pouches through normal running and a controlled restart.
| Change area | Setup evidence | Release evidence |
|---|---|---|
| Product and dose | Product identity and condition, filler recipe, feed method, contact parts and cleaning status. | Measured dose, stable replenishment and clean transfer into the pouch. |
| Pouch or film | Approved drawing, supplier reference, change parts, guides, grippers or forming set. | Repeat feeding, opening or forming, correct dimensions and undamaged features. |
| Fill zone and seal | Headspace, settling, jaw recipe, alignment and product-free seal band. | Approved filled shape, seal appearance and the agreed integrity check. |
| Code and inspection | Artwork, recipe, sensor, challenge and reject settings. | Readable code, detected challenge, rejected pouch and recorded result. |
| Line sequence | Ready, blocked, fault and restart states with connected equipment. | Controlled stop, no uncertain pouch released and repeatable recovery. |
Use a controlled setup sheet, install or adjust the identified parts, load the approved recipe, perform safe empty-cycle checks where applicable, make first-off pouches and verify dose, pack presentation, seal, code and inspection. Complete a short stability run and a restart check before the format is released.
Retain the approved pouch and results as the reference for the next repeat changeover.
Any change that can affect product flow, pouch handling, fill height, seal formation, coding, inspection or line sequence needs an appropriate first-off check. This includes new product batches where condition changes, new packaging lots, a different dose, change parts, supplier changes and maintenance affecting critical settings.
The extent of revalidation should match the process risk created by the change.
Record the product and pack reference, machine recipe, change parts, mechanical references, cleaning status, setup checks, first-off results, retained sample, operator, date, deviations and release decision. Include code and inspection recipes where they are part of the line.
The record should let another trained operator reproduce the approved setup without relying on memory.
A recipe is not enough when physical adjustments, component identity, pouch variation, product condition or wear can change the result. Saved values do not prove correct change parts, gripper position, film path, nozzle clearance, clean seal area or the response to a stop and restart.
Combine electronic recipes with physical references and first-off evidence.
Match the job, product, pouch or film, dose, code and quality schedule to the approved specification.
Complete the required isolation, cleaning, inspection and change-part controls under the site's safe system of work.
Install the listed parts, load the correct recipe and set physical references that are not controlled electronically.
Where the procedure permits, verify feed, opening or forming, grip, transfer, sealing and discharge without dosing.
Check dose, filled profile, seal, code, inspection, reject and presentation against the written release criteria.
Run the agreed sequence, include replenishment or restart challenges and retain the approved evidence.
Confirm the handling window and how an unopenable pouch is controlled.
Open the handling guide →Keep the product below the closure and seal area after the dose settles.
Open the fill-zone guide →Carry the approved changeover into FAT, SAT and production handover.
Open the acceptance guide →Lancing can review the pouch range, dosing route, change parts and evidence needed for repeatable changeovers.
