Tube with twice-scored flaps Box Template Generator

Tube with twice-scored flaps. A glued four-panel tube whose eight flaps each carry two score lines: a narrow band at the body edge, then the flap itself, so the closed flaps stand off the wall by the width of the band. Length here is the tube height, which is the plate’s un-creased dimension.

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 Tube with twice-scored flaps?

Tube with twice-scored flaps is a carton insert or fitment. A glued four-panel tube whose eight flaps each carry two score lines: a narrow band at the body edge, then the flap itself, so the closed flaps stand off the wall by the width of the band. Length here is the tube height, which is the plate’s un-creased dimension.

Uses

High-volume packing lines, since a pre-glued blank erects in one movement

Advantages

Cut from a single blank, so there is one tool and one part to stock
Arrives glued and flat, and erects quickly by hand or by machine

Disadvantages

The glued joint sets the minimum order — short runs are rarely economical

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.
