Rectangular tube lined on both long walls Box Template Generator

Rectangular tube lined on both long walls. The lined tube taken one wall further: after the tube the strip returns, runs back along one long wall, returns again and runs back along the other, so both long sides are doubled.

What is Rectangular tube lined on both long walls?

Rectangular tube lined on both long walls is a carton insert or fitment. The lined tube taken one wall further: after the tube the strip returns, runs back along one long wall, returns again and runs back along the other, so both long sides are doubled.

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 0.993, MATCH, cut 0.995 found / 1.000 extra, crease 1.000 / 1.000. Rectangle 203.81 by 39.21, eight vertical folds, run 6.12, 36.77, 6.12, 36.76, 6.13, 37.17, 18.79, 37.16, 18.79. The arrows put A = 37.17 and B = 18.79, so the last four panels are the tube at 2(A+B) = 111.92 and the five before it are two liner walls separated and ended by three returns. The liner is 0.9891 of its wall — the same two-thickness allowance F80.21 draws.
