Produce & Greengrocer Tray

Reading the code FEFCO 0422

The 04 series holds the folder-type boxes and trays: usually one-piece, unglued constructions erected by folding the die-cut blank around or under the product. This is the series of trays, folders and mailers that hold their shape by geometry — locking tabs, ears and hinged lids instead of a glued joint.

Within the series, 0422 is the design published as the Self-Locking Tray with Double End Walls and Locks. The four-digit code carries the full structural intent — specify it to any converter and both sides mean the same construction; only dimensions and board grade remain to be agreed.

How the case behaves

The base carries single side walls and double end walls. Each end wall folds up, folds back over itself and drops its locking tabs into slots in the base; the side walls' dust flaps are trapped inside the doubled wall as it closes, which is what squares and stiffens the tray. The 0423 variant doubles the long side walls instead.

Typical uses

Unglued self-locking trays are erected at the point of use: produce and bakery trays, transit trays for jars and cans, counter-top and display trays, and inner trays that organize a larger pack.

Dimensions and board

The parameters above — internal length, width and depth, plus any construction-specific values this style needs — drive the whole blank: panel layout, flap depths and slot positions all derive from them, validated against the template's supported range. The 2D dieline and the 3D fold preview regenerate together from the same parametric structure.

A corrugated dieline is a starting point for production, not a substitute for converter judgment: flute profile, board grade and joint style all affect final dimensions and crush behavior. Confirm tolerances and material with your manufacturer before mass production — and erect the structure on screen first, so flap collisions and proportion problems surface before any tooling is ordered.

Industries and applications

Converters cut the Produce & Greengrocer Tray (FEFCO 0422) for fruit and vegetable trays and food and dry-goods cartons.

Produce trays are erected at the packhouse, stacked wet and sold straight from the tray, so the locks have to hold without glue.

What is Produce & Greengrocer Tray — Self-Locking, Double End Walls with Locks?

FEFCO 0422 is a self-locking open tray with double end walls: the end walls fold double and lock by tab and slot, with dust flaps folded inside them. One blank, no lid, no glue, built for produce and goods displayed in the tray they travel in.

Which dimensions does the Produce & Greengrocer Tray — Self-Locking, Double End Walls with Locks dieline need?

4 parameters drive the blank: L (length), W (width), D (depth), Corrugated cardboard thickness (mm). Each value is validated against the template's supported range, and the whole dieline regenerates from them.

Can I see how Produce & Greengrocer Tray — Self-Locking, Double End Walls with Locks folds before cutting it?

Yes. The interactive 3D fold preview and the 2D dieline are generated from the same parametric model, so the fold you watch on screen is the geometry of the sheet you cut. Open the template in the studio to fold it at your own dimensions; 3D folding comes with the Workshop and Line plans.
