How to use this mockup

  1. Start from the 3 side 80 × 120 mm sample or type your own size.
  2. Design straight on its real dieline.
  3. Turn it in 3D, export a picture or video, or stage a scene.

Trade tips

  • The tuck flap is the first thing a buyer sees when opening: print a note or instructions inside it.
  • Run the artwork 3 mm past the cut line and keep text 3 mm inside it.
  • Ivory board prints best on its coated face; keep the uncoated inside to one colour.
  • Matte lamination feels premium and softens colours by about a shade: add contrast in the design.

Questions

Is the triangular cake sleeve mockup free?

Yes, commercial use included; Free adds a watermark grid at 1K, Pro exports 4K without it.

Can I use my own size for the triangular cake sleeve?

Yes — from the 3 side 80 × 120 mm sample or your own size, with the dieline redrawn.

Can I get the triangular cake sleeve dieline for printing?

Yes, with Pro: the die files (SVG, PDF / AI, DXF / CF2) and the CMYK print PDF; designing on the die is free.

What is the triangular cake sleeve sample printed on?

The sample is ivory (C1S board) 300 gsm with matte lamination, on a dieline drawn at the size you type.

Construction

A sleeve is a strip of board folded into a polygon tube open at both ends, glued along one seam or locked with two tabs, and slid over a tray or cake box. It holds the tray lid on and carries the brand and information instead of printing the whole pack; the triangular version hugs a film-wrapped sandwich wedge.

Choosing board and material

250–300 gsm ivory or kraft is plenty because a sleeve carries no load, it only wraps; sleeves on chilled food trays should be laminated against condensation. As long as a tray or film sits inside, the sleeve doesn't touch the food and needn't be food-contact board.

Finishing

The sleeve concentrates the branding, so foil, spot UV or one bold colour on kraft all work well. Matt lamination lets it slide on smoothly without scuffing.

Preparing the print file

The widest face is the front; put product name, ingredients and dates required on the label on the back or underside. The sleeve's inside perimeter should be 2–4 mm larger than the tray's so it slides on without being loose; keep the barcode on a flat face, never across an edge.

Common mistakes

  • Matching the sleeve perimeter exactly to the tray: it grips too tight and customers tear it or crush the bake pulling it off.
  • Making the sleeve too narrow for the tray: the tray slides out when carried at an angle.
  • Printing the best-before on the clear tray and then covering it with the sleeve.
  • Using board under 200 gsm on a trapezoid sleeve: the edges won't hold their angles and it goes round and slack.

Questions and answers

How does an 80 × 120 mm triangular sleeve fit a sandwich?

The 80 mm-sided, 120 mm-long sleeve slides over a film-wrapped sandwich wedge, open at both ends so the filling shows; it costs less than a closed wedge box yet carries the name and date.

Does a sandwich sleeve stop the wedge being crushed?

Only lightly; sandwiches stacked in a chiller still need a plastic or card wedge inside, with the sleeve handling branding and information.

Can a sleeve replace a sticker label?

Yes. It is label and lid-holder in one, looks more finished than a sticker and changes seasonally without changing the tray; it still has to carry all mandatory information.

Do polygon sleeves ship flat?

Yes. Glued sleeves ship flat and are popped open to slide the tray in; tab-locked versions arrive as flat blanks.

How wide should a sleeve be relative to the pack?

Covering 40–60% of the tray length holds it securely while showing the product; extend it near the tray edge if it should also act as a tamper seal.
