FEFCO 0457 — Self locking tray hooks.
Made for: Fashion & retail, Food & specialties.
Sample printed on brown-liner corrugated board, uncoated; style: cartons and boxes by FEFCO code (dividers, handles, trays, displays…).
Sample size 400 × 300 × 120 mm.
Folder boxes and trays (FEFCO 04): one corrugated sheet folded round a floor, no glue — doubled walls with locks, a hinged lid with a tuck, display trays, mailers. Die-cut once, folded by hand on site.
Yes, commercial use included; Free adds a watermark grid at 1K, Pro exports 4K without it.
Yes — from the 400 × 300 × 120 mm sample or your own size, with the dieline redrawn.
Yes, with Pro: the die files (SVG, PDF / AI, DXF / CF2) and the CMYK print PDF; designing on the die is free.
The sample is brown-liner corrugated board with no lamination, on a dieline drawn at the size you type.
The FEFCO 04 family covers folder boxes and trays cut from a single corrugated blank (a few use two pieces): the base sits in the middle of the blank and the walls and lid fold up from it, with no manufacturer's joint as on a 02 slotted case. Corners are held by locking tabs in slots, by double walls whose lugs push into the base, or by corner flaps that are glued or stapled, depending on the code. Most ship flat and are erected by hand or on a tray-forming machine at the packing line.
Mailers and retail boxes usually run on E flute (about 1.2–1.8 mm) or B flute (about 2.5–3 mm), with a white kraft liner when print matters and brown when it only carries a logo. Produce trays and heavy-duty displays use B, C or BC double wall; trays going into cold rooms want a moisture-resistant liner. The thicker the flute, the more the creases need allowance, or double walls and lids will bind and gape.
Direct flexo in one to three colours on the liner is the norm for trays and high-volume mailers; branded boxes are printed offset on paper and litho-laminated onto E flute for sharp images. Printing the inside of the lid creates an unboxing moment; lamination belongs only on litho-laminated work, and keep foil or spot UV off the crease zones of locking tabs.
Lay out on the flat dieline remembering the base is in the centre: lid, front and back walls face different directions, so type must be rotated to read correctly once the box is erected. A double wall has two layers — the outer face shows outside, the folded-in layer shows from the opening — and both sit on the printed side. Allow 3–5 mm bleed and keep copy at least 5 mm from creases, where the flutes push the print off line.
Each corner flap carries an L-shaped hook that locks into a slot in the long wall — strong enough for a few kilos, and the tray can be knocked flat and reused.
Small hooks in E flute fray after a few cycles; B flute holds them better, and E flute only suits small single-use trays.
A 02 case has a glued manufacturer's joint and flaps at both ends of a tube; a 04 folder has no body joint — the base is one flat panel and the walls and lid fold up from it. That makes 04 styles the natural choice for mailers, trays and book boxes with a clean flat top.
Many styles lock with tabs and lugs and need none; some trays have corner flaps that are pre-glued or stapled for fast machine erecting. If the dieline shows a glue flap, that style is glued.
E flute for light goods, a fine print surface and neat folds; B flute once the contents weigh a few kilos or travel far by courier, at the cost of rougher creases and more thickness allowance on the die.
