FEFCO 0321 Box Template Generator

Twin telescoping slotted bodies with locks. Two slotted wraps telescoping together. The closing flaps run past the centreline: one long flap is notched back to the centre, the opposite one is a trapezoid whose tip drops into that notch, and the two short flaps are mitred so they pass underneath. The pair holds itself closed at both ends without tape.

Not yet plate-checked. This template folds, closes and exports cleanly, but its blank has not yet been matched against the standard's own drawing in detail. Treat it as a starting point and check it before you spend anything.

What is FEFCO 0321?

FEFCO 0321 is built from two or more pieces, most often a separate lid over a body, so the depth can vary with what is packed. Two slotted wraps telescoping together. The closing flaps run past the centreline: one long flap is notched back to the centre, the opposite one is a trapezoid whose tip drops into that notch, and the two short flaps are mitred so they pass underneath. The pair holds itself closed at both ends without tape.

Uses

Jobs where the depth or the fit has to be adjusted after packing

Advantages

Locks closed without glue or tape, which saves a consumable and a step
The two parts can be made from different boards, or printed differently

Disadvantages

Needs 2 separate pieces, so there is more than one tool and more than one part to handle
Hand-locking takes longer per box than a taped or glued closure

Typical industries

General packing and light manufacturing

Recommended board grades

Single wall B or C flute is usual. The lid and body are often the same board; a heavier body under a lighter lid is worth considering where only the body carries the stack.
