Shallow tray with hollow walls and curved shelves Box Template Generator

Shallow tray with hollow walls and curved shelves. A shallow tray whose side walls fold out into a hollow section — up, in over a ledge, back down inside, and a foot under the base — with a curved shelf folded in from each end, leaving a slot between them.

Checked against the plate. This blank has been compared side by side with the drawing in the FEFCO Code, 12th Edition, and matches. That is a statement about the drawing, not a guarantee — always cut and fold a sample before committing to a die.

What is Shallow tray with hollow walls and curved shelves?

Shallow tray with hollow walls and curved shelves is a carton insert or fitment. A shallow tray whose side walls fold out into a hollow section — up, in over a ledge, back down inside, and a foot under the base — with a curved shelf folded in from each end, leaving a slot between them.

Uses

Retail and gift packaging, where the box is seen by the customer

Advantages

Cut from a single blank, so there is one tool and one part to stock

Disadvantages

No standard style suits every product; check the fit against a sample before committing to a tool

Typical industries

General packing and light manufacturing

Recommended board grades

Folding boxboard or solid bleached board, typically 250–450 microns. Heavier board for larger cartons, lighter where the carton is filled by machine.

Measured against the p.71 plate with scripts/plate-diff.py: score 0.965, MATCH, cut 1.000 found / 1.000 extra, crease 1.000 / 1.000. Wall section H, 2H/3, H, 2H/3 either side of the base: 2 x (H + 2H/3 + H + 2H/3) + B is 122.73 against the 122.71 drawn. Both shelves are PDF curves, which the plate reader flattens to their Bezier control polygons and so reports 1.8 taller at the top than the page prints; this draws the curve, and the 0.965 rather than 1.000 is that difference.
