Custom Printed-Inside Mailer Boxes
Custom printed-inside mailer boxes are self-locking FEFCO 0427 roll-end tuck-front (RETF) corrugated mailers printed on both the exterior panels and the interior lid, walls, and floor. They let brands pair a clean or stealth outer box with a bold interior flood coat, welcome message, or QR code. Minimum 250 boxes in 10–14 business days (4–5 day rush), with free US shipping.
What are custom printed-inside mailer boxes?
Custom printed-inside mailer boxes are one-piece die-cut corrugated shipping mailers built in the FEFCO 0427 roll-end tuck-front (RETF) architecture with custom artwork printed on the interior linerboard (or on both the exterior and interior liners). When a customer lifts the front cherry-lock lid of a roll-end tuck-front mailer, the hinged top panel swings open to a natural 95-to-110-degree reading angle directly at eye level, while the double-rolled side walls frame the product like a miniature stage. Printing that interior canvas transforms an ordinary parcel into a shareable unboxing moment: brands use the inside lid for bold welcome headlines, founder notes, onboarding step checklists, and scannable reorder QR codes, while flood-printing the inner floor and side walls in signature brand colors or botanical patterns. Available from 250 units in E-flute or B-flute corrugated board. Every two-sided box ships flat and folds together by hand in seconds without tape or glue.
How does two-sided printing work on a FEFCO 0427 mailer box?
A custom printed-inside mailer box shares the exact FEFCO 0427 roll-end tuck-front (RETF) structural geometry of our parent custom mailer boxes, adding a second printed liner sheet on the interior side of the fluted corrugated medium. Whether your team searches for two sided printed mailer boxes, mailer boxes printed inside and out, interior lid printed subscription boxes, unboxing message inside mailer boxes, double sided cmyk corrugated mailers, inside flood coat printed mailer boxes, or qr code printed inside mailer lid, our prepress team maps both Side A (Outside) and Side B (Inside) on one coordinated CAD dieline.
- 1Interior lid billboard (eye-level welcome panel)
Presents your welcome headline, brand story, social hashtag, or QR code at eye level the instant the customer lifts the front lid. - 2180-degree double-rolled interior side rails
Because the side walls fold up 90 degrees and roll 180 degrees inward into floor slots, the outer side-flap panels wrap your interior flood color over both side rails. - 3Printed interior floor & dust wings
Frames products (or a matching card/foam insert) with edge-to-edge color or repeating patterns across the bottom tray and side dust flaps. - 4Contrast exterior shell (white, kraft, or black)
Pair a minimalist logo or stealth unbleached kraft exterior (to deter porch theft) with a vibrant full-color interior reveal. - 5Interior aqueous seal or matte lamination
Seals heavy interior ink coverage so dark flood coats never rub off onto white apparel, frosted jars, or tissue paper during parcel vibration.

What are the 5 most common mistakes on custom printed-inside mailer boxes?
Whether you are ordering wholesale inside printed mailer boxes, influencer unboxing inside print mailers, custom printed inside mailers from 250, kraft outside colored inside mailer boxes, clean exterior bold interior mailer boxes, two pass printed corrugated mailers, or working with a custom inside print mailer box supplier, avoiding these five prepress errors guarantees a flawless interior reveal
- Orienting the inside-lid welcome message in the same top-to-bottom direction as the outside lid on the flat dieline, which causes the interior text to appear upside down when the customer opens the box toward themselves.
- Forgetting to extend the interior flood color onto the outer side-wall roll-over panels on Side A, leaving two unprinted white strips along the left and right interior walls after the side walls roll 180 degrees inward.
- Printing dark navy, black, or forest-green interior flood coats without an aqueous satin seal or matte lamination, allowing ink to rub onto white t-shirts or frosted cosmetic jars during parcel vibration.
- Placing text or QR codes within 1.25 inches of the left and right edges of the inside lid, where the folded top side dust wings swing inward and cover the outer margins.
- Specifying all-kraft corrugated board (brown inside) for delicate pastel pink, baby blue, or yellow interior artwork instead of choosing Kraft-Outside / White-Inside hybrid board.

How does two-sided printing work on custom printed-inside mailer boxes?
We print the outer linerboard sheet (Side A) and the inner linerboard sheet (Side B) separately on high-resolution offset litho or digital presses before laminating them to the fluted corrugated medium and die-cutting the FEFCO 0427 blank. This allows 100% edge-to-edge full-bleed color on both the outside and the inside of the box.
Why do D2C and subscription brands print a surprise design or QR code inside the mailer lid?
When a customer opens a roll-end tuck-front mailer, the hinged lid stands upright like a billboard at eye level. Printing your welcome message, onboarding steps, and a scannable QR code on the inside lid captures 100% customer attention while eliminating the cost and packing labor of a separate printed postcard.
Can I keep a simple stealth exterior for shipping security and print full color inside the mailer box?
Yes. Many jewelry, electronics, apparel, and beauty brands keep the exterior plain brown kraft (or print only a tiny return address) to deter porch theft in transit, then flood-print the entire interior cavity in vibrant brand colors and metallic foil.
What is the minimum order quantity for custom printed-inside mailer boxes?
Our minimum order quantity is 250 custom printed-inside mailer boxes. Every order includes a free two-sided 2D vector CAD dieline and an interactive 3D digital proof showing both the closed exterior and open interior before payment. Every order includes a free two-sided 2D vector CAD dieline and interactive 3D digital proof showing both your exterior and interior artwork before you pay.
How do I set up the outside and inside artwork layers on a two-sided mailer dieline?
We supply a two-artboard vector PDF/AI dieline template: Artboard 1 is Side A (Outside view) and Artboard 2 is Side B (Inside view). Rotate your inside-lid artwork 180 degrees relative to the outside lid so it reads right-side up when hinged open, and color the side-wall roll-over flaps on Side A to match your interior walls.
Does printing inside the mailer box require white corrugated board on the interior liner?
If your interior artwork uses pastel tints, gradients, photography, or bright Pantone colors, specify a bright white interior liner (either All-White board or Brown-Kraft-Outside / White-Inside hybrid board). If your interior design uses bold black, white, or dark ink on an earthy background, you can print directly on a brown kraft interior liner.
How much does adding interior printing change the unit cost compared to outside-only printing?
Adding interior printing typically adds only a modest second-pass print setup across a 250 to 5,000+ box run, and often saves money overall by eliminating the need to print, inventory, and hand-stuff separate welcome postcards or tissue paper.
Can I pair an inside-printed mailer box with a matching printed insert or tissue paper?
Yes. We can co-engineer a fitted 18–24 pt paperboard tray, 32 ECT E-flute corrugated cradle, or card-laminated EVA foam insert printed on the exact same press run so the insert deck cleanly continues your interior lid artwork. Every order includes a free two-sided 2D vector CAD dieline and interactive 3D digital proof showing both your exterior and interior artwork before you pay.
Are there any plate or die charges for two-sided printed mailer boxes?
No. CubitPack charges zero steel-rule cutting die fees and zero printing plate setup charges on two-sided printed mailer boxes from 250 units. Every order includes a free two-sided 2D vector CAD dieline and interactive 3D digital proof showing both your exterior and interior artwork before you pay.
