Corrugated · Packaging buyer’s guide
A mailer with printed interior panels needs an artwork plan that follows the assembled opening sequence. Areas that look adjacent on a flat dieline may face different directions once the box is folded.

The short answer
Plan graphics against the assembled opening sequence. The outside, inner lid, and product-facing panels need the correct orientation when folded. Keep required closure and shipping-label areas clear and inspect a printed assembled sample for alignment.
What to review before approving production
Mark the first view, the inner lid, and the product-facing panels on a physical mockup. Reserve closure and carrier-label areas where required. Review scuffing and fold alignment on an assembled printed sample before approving the full artwork.
