Gusseted expanding envelope Box Template Generator

Gusseted expanding envelope. An envelope with a gusset folded into the sides and base so it expands to hold a thick wad of documents rather than splitting. The one that survives a full set of drawings.

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.
