Why mailer boxes are different
A shipping box isn't just a container — for an e-commerce brand it's the first physical moment with your customer. That makes the inside of the box as important as the outside. Most designers ignore the interior flaps; brands that don't get hundreds of free Instagram and TikTok impressions when their customers post the unboxing.
Pack AI treats every panel — exterior, interior, dust flaps, glue tabs — as a design surface. Pick which ones to brand and which to leave clean.
What you can design on a mailer
- Exterior — logo, brand wordmark, shipping label area, return address block
- Interior flaps — thank-you note, discount code for next purchase, social handles, QR code to a video
- Bottom panel — a hidden message most buyers don't notice until they break the box down
- Tear strip area — clear opening instructions
- Brand colors as solid backgrounds or gradients across selected panels
- Patterns or repeating illustrations as background fills on the interior
Mailer formats Pack AI handles
Roll-end tuck-top, full-flap mailers, corrugated mailers, literature mailers, book wraps — anything your supplier delivers as a vector template. Pack AI parses the flat blueprint and detects each panel automatically so you can design without thinking about which face is which.
