Key Takeaway
A packaging dieline is a precisely measured flat template showing where a package will be cut, folded, creased, glued, and assembled so artwork can be positioned correctly before printing. It normally identifies panels, cut lines, fold lines, glue areas, bleed, safe zones, dimensions, and orientation. Keep structural guides on a separate nonprinting layer, extend backgrounds through the bleed, and keep text, logos, barcodes, and finishes inside their safe areas. Confirm the dieline matches the intended material and product dimensions, then review a digital proof before production. For exact fit or complex construction, test a physical unprinted sample before approving final artwork.
