Вака изгледаат: http://www.paperbagsethiopia.com/side-gusset-bags/. По МК страници ги наоѓам како хартиени кеси за леб, кеси за пецива, но ми треба превод којшто не ја потенцира намената, туку обликот што се формира во средниот дел што има, да ја наречам „фалта“.

Gussets are also used when making three-piece bags, for example in a pattern, for a bag as a long, wide piece which connects the front piece and back piece. By becoming the sides and bottom of the bag, the gusset opens the bag up beyond what simply attaching the front to the back would do. With reference to the dimension of the gusset, the measurements of a flat bottom bag may be quoted as LxWxG.
Special envelopes will also employ a gusset to allow for expansion when containing more than just a few sheets of paper for example.
