Rectangular tube with a lined long wall Box Template Generator

Rectangular tube with a lined long wall. A four-panel tube that carries on past the joint into a return, a second long wall and a second return, so one long side is doubled and stands clear of the outer wall by the width of the returns.

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 Rectangular tube with a lined long wall?

Rectangular tube with a lined long wall is a carton insert or fitment. A four-panel tube that carries on past the joint into a return, a second long wall and a second return, so one long side is doubled and stands clear of the outer wall by the width of the returns.

Uses

Protecting or separating goods inside a larger case

Advantages

Cut from a single blank, so there is one tool and one part to stock
Cut from offcuts or lighter board than the outer case, so it adds little cost

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.84 plate with scripts/plate-diff.py: score 0.981, MATCH, cut 0.984 found / 1.000 extra, crease 1.000 / 1.000. A bare rectangle 203.81 by 53.75 with six vertical folds and nothing else on the page. Panel run 17.36, 50.95, 17.36, 50.95, 8.40, 50.39, 8.40; the plate's own arrows give A = 50.95, B = 17.36 and b = 8.40. The first four panels are exactly 2(A+B) = 136.62, so they are the tube, and the return-liner-return that follows is the doubled rim the isometric draws. The liner is 0.989 of the wall it lines, which is two board thicknesses at the plate's scale.
