Choose and position a glue tab
Give a join enough useful overlap while keeping its adhesive and paper out of the usable space.

Follow the adjoining faces
A glue tab belongs to one panel and is bonded to a different panel after folding. Identify that target face before cutting. The hatching marks adhesive area; it is not an extra wall or a cutout.
On a sleeve, the long seam tab joins the first and last panels into a band. On an open tray, corner tabs join neighbouring walls. Those tasks have different available space, so one tab width is not appropriate everywhere.
Keep the tab inside the construction
A larger tab can reach a fold, overlap another closure or protrude beyond a short wall. The generator limits these relationships for each structure. If a requested tab is rejected, reduce it or reconsider the nearby panel dimensions rather than forcing an invalid net.
In a 40 mm-high tray wall, a 30 mm corner tab can fit within the corner recess. That observation does not mean 30 mm will suit a much shallower tray. Check the actual drawing after changing height.
Dry-fit before adding adhesive
Pre-fold the tab and hold the target wall in place. Check that the corner closes squarely and no tab appears above the rim. Apply a thin controlled adhesive layer within the hatch, then hold the join until it is stable.
Different papers and glues behave differently. Try the combination on scrap and allow the bond to settle before judging the final shape. Keep adhesive away from an envelope pocket or sleeve opening where it could catch the contents.
