Mark the physical boundaries
Start with a drawing that shows the cut outline, front and back, seal area and intended opening point. Include the artwork orientation as it will appear on the filled pack. Ask the filling team to confirm the drawing version and any areas where printing or text placement would interfere with sealing, opening, production marking or legibility.
Give lot and date codes a place
Identify where any required production codes should appear and how much space the proposed marking method needs. Confirm the text and code format with the project team. A light or plain area may make the mark easier to read, depending on the film and ink. Request a proof or coded filled sample to verify the actual contrast and placement.
Check how the user reads the pack
Hold a filled sample as a customer would and look at the instruction order, the opening cue and the most important text. For a pack inserted in a kit, check how the pouch sits in the outer package and how the recipient identifies it after removal. Verify that filling and packing do not hide or distort text the buyer needs.
Document approval before print
Send the annotated drawing, artwork file version and a photo of the approved filled sample together. Keep agreed manufacturing marks and the visual proof in the same approval record. If the pouch supplier, shape or dimensions change, ask for an updated drawing and compare it to the original before reusing artwork. Record who can approve revisions and where the approved files are stored.
