How does a two-piece tray and sleeve box dieline work?

What are the two pieces on a tray and sleeve box dieline?

Unlike a one-piece carton such as a straight tuck end box or mailer box, a custom tray and sleeve box uses two coordinated vector templates that we place on a single Adobe Illustrator artboard

1. Piece A (Four-panel tubular outer sleeve): Laid flat, the sleeve consists of four continuous panels wrapping around the tray: the Top Display Panel (W × L), Left Side Wall (H × L), Bottom Panel (W × L), Right Side Wall (H × L), and a longitudinal Glue Lap (0.5 to 0.75 in wide) on one outer edge. Both ends of the sleeve are clean cut lines with optional half-moon thumb notches.
2. Piece B (Rolled double-wall inner tray): Centered around the rectangular Tray Floor (L × W). Radiating from all four edges of the floor are the Outer Side and End Walls, parallel Rollover Crease Bridges (0.125 to 0.25 in wide), Inner Locking Walls with foot tabs that snap into floor perimeter slots, and four Corner Dust Flaps.
3. Single-sheet vs split-sheet nesting: If both pieces use the same paperboard and finish, we nest Piece A and Piece B on the same press sheet. If you want a printed white card sleeve over a natural brown kraft or E-flute corrugated tray, we run each piece on its own stock.

How do outer sleeve panels, windows, and thumb notches work?

Because the outer sleeve has no end tuck flaps, 100% of its four main panels act as an uninterrupted 360-degree billboard around your product. Follow these structural rules when laying out your sleeve artwork

1. Top panel and bottom glue-seam placement: The longitudinal glue lap bonds the far edge of the right side wall to the inside of the bottom panel so the top display panel and both side walls stay completely seam-free.
2. Die-cut window keep-out margin (minimum 3/8 in / 9.5 mm): Whether you choose an open window cutout for custom soap boxes or a clear PET film-patched window for custom macaron boxes and custom chocolate boxes, keep every edge of the window opening at least 0.375 inches away from the four vertical score lines and the two open ends of the sleeve. Cutting closer weakens the sleeve frame and leaves too little margin for the window patch adhesive.
3. Thumb notch clearance (minimum 1/4 in / 6.35 mm): If your sleeve includes half-moon thumb notches on one or both open ends so shoppers can pinch the inner tray, keep logos, foil borders, and body text at least 0.25 inches back from the notch cut line.

How does outer print wrap over the rolled double-wall tray?

Look closely at each of the four walls on the inner tray dieline and you will see two parallel red crease lines separated by a narrow bridge strip (0.125 to 0.25 inches wide). During assembly, the four corner dust flaps fold 90 degrees inward first, and each outer wall folds 90 degrees up and rolls 180 degrees down over the corner flaps so its locking foot tabs snap into die-cut slots along the tray floor.

1. Free interior wall color from a 1-sided press run: Because the outer coated face of the paperboard wraps up the outside tray wall, crosses the top rim bridge, and drops all the way down the inside tray wall, extending a solid flood color or pattern across those panels on the outside of the sheet automatically prints the inside walls of your open drawer at no extra 2-sided print cost.
2. Covering or printing the tray floor: On a 1-sided press run, only the flat center floor of the tray shows the unprinted white or kraft back side of the board. If your product does not cover the floor, you can either add a printed card insert/divider or upgrade the tray to 2-sided printing.
3. Ribbon pull-tab slot placement: If you add a satin ribbon pull tab on the front end wall of the tray, our CAD template places two narrow horizontal die-cut slots centered on the outer and inner end-wall panels so the ribbon tails lock invisibly inside the double wall.

What are the pre-press bleed, safe zone, and line color rules?

When we send your custom CAD dieline after you measure your product, the vector lines sit on a locked top layer in Adobe Illustrator. Use the table below to check every layer before exporting your press-ready PDF

How do I get a custom tray and sleeve dieline and 3D proof?

Still deciding whether you need a two-piece tray and sleeve carton, a simple belly band, or a 2 mm rigid setup drawer? Read our comparison of tray and sleeve vs sleeve-only and rigid drawer boxes. When you request a quote on CubitPack (from 1,000 boxes, with 10–14 business days standard turnaround or 4–5 business days rush), our packaging specialists email your exact two-piece vector dieline template at no charge. Every order includes free design help, a free digital proof, and a free 3D mockup before payment, with zero die or plate charges and free shipping across all 50 US states.

1. Confirm slide orientation between sleeve and tray: Verify that your outer sleeve front panel matches the end of the tray that holds your thumb notch or ribbon pull tab so the drawer pulls out from the intended side.
2. Extend background artwork across the tray wall bridge: Carry your outer tray wall color across the 0.125–0.25 inch top rollover bridge and down the inner locking wall panel so the inside walls of the open drawer are colored in one press pass.
3. Outline all fonts and embed 300 DPI CMYK links: Convert every typeface to vector outlines, keep text 0.125 inches inside score lines, and place metallic foil or spot UV on separate 100% vector overprint layers.

What are the most common artwork and dieline mistakes on tray and sleeve boxes?

Check your Illustrator file against these five pre-press errors before sending art to press

1. Placing a die-cut sleeve window closer than 3/8 inch (9.5 mm) to the vertical fold lines or open ends, which causes the sleeve bridge to bow or tear when sliding.
2. Printing ink or applying soft-touch lamination over the longitudinal sleeve glue lap, which prevents folder-gluer adhesive from bonding into paper fibers.
3. Stopping outer tray wall artwork at the top crease instead of continuing the background color across the rollover bridge and inner locking wall panel.
4. Orienting the bottom sleeve panel artwork upside down relative to how customers flip the box over in hand.
5. Applying thick soft-touch film to both the inside of the outer sleeve and the outside of the inner tray walls without widening the slide clearance to prevent rubbery friction drag.
