What this box is, in other words
Cakes, tarts, cupcakes, cookies and macarons: bakery goods the customer wants to see before the box is opened, in one box with a hinged lid.
How it closes. The takeaway box with a rounded window cut into the lid. The base is a glued corner tray; its back wall carries on into the lid, which closes down over the outside of the base. Clear film is glued on the inside of the lid, over the window.
Worth knowing. The window frame is measured from the inside of the walls, so the lid keeps a solid strip on all four wall tops. If the frame would leave an opening under 20 mm, the tool leaves the window out and says so. The film is not part of the file: cut it about 10 mm larger than the window on every side. If the cake touches the board, ask your supplier for food-contact grade board.

Same construction, different trade. If you came looking for one of those, this is it.
How this one is built
- Takeaway box: a glued corner tray with a lid hinged on its back wall. The lid closes down over the outside of the base.
- The back wall is 101.5 mm, one board higher than the inside height plus half a board, so the lid lies flat on the wall tops.
- The lid side walls stand 0.4 mm clear of the base; at the front the lid is one board wider (3.4 mm) because its corner tabs sit between the two front walls.
- The lid reaches 30 mm down the base walls. It holds by friction; a sticker on the front keeps it shut in transport.
- All six corner tabs need glue.
- Window 140 x 140 mm in the lid, 30 mm in from the inside of the walls. Glue a sheet of clear film behind it, on the inside of the lid, overlapping the opening by about 10 mm.
Board options
The drawing changes when you change the board: thickness compensation is built into every fold, so a 4 mm C-flute blank is not the same shape as a 0.45 mm carton blank.
- F-flute corrugated (0.8 mm)
- E-flute corrugated (1.5 mm)
- B-flute corrugated (3.0 mm)
- C-flute corrugated (4.0 mm)
- EB double wall (4.5 mm)
- BC double wall (7.0 mm)
- SBS / GC1 board 350 gsm (0.45 mm)
- FBB / GC2 board 400 gsm (0.55 mm)
- Kraft / GD2 board 400 gsm (0.50 mm)
- Greyboard 1.0 mm (rigid)
- Prototype board 1.0 mm

Questions about this box
- Is the window a real curve in the file?
- Yes. The rounded corners are arcs in the SVG and PDF and bulges in the R12 DXF.
- What film goes behind the window?
- Any clear film that is safe for food packaging, glued or taped on the inside of the lid. PET is common; cellulose film is the plastic-free choice. Ask your printer or supplier what they stock.
- Is there a FEFCO or ECMA code for a cake box with window?
- Not one we could check against the catalogues for this construction, so the tool does not print one.
- Is this dieline free?
- Designing it and folding it in 3D are free and need no account. Downloading it is paid: €2.50 for the PDF to print and measure on paper, and €3.50 for a production file - DXF or SVG - because those are the ones that go to a cutting table.
- What is a dieline?
- The flat drawing a box is cut from. It shows where the knife cuts, where the board is creased to fold, and where it is perforated. A die maker turns it into a steel rule die; a plotter or laser cuts it directly. It is also written as "die line" or "die cut template".
- What file format does a die maker need?
- DXF, almost always. Ours is R12 DXF at 1:1 in millimetres with cut, crease, reverse crease and perforation each on their own layer, which is what a cutting table expects. The SVG is the same geometry for Illustrator, Affinity, Inkscape and laser software.
- Can I use it commercially?
- Yes. The files are yours: modify them, print them, make any number of boxes from them. No attribution and no licence fee, ever.
