MAILmedia Gusseted Kraft Paper Bag, 100 x 40 x 600 mm, Brown, 32 g/m², Without Window, 1 Piece (30131539)

Shipping long or bulky lightweight items often means choosing between oversized boxes and flimsy envelopes. This gusseted kraft paper bag solves that problem with a slim 100 mm width and a 40 mm expandable side gusset, giving you a 600 mm long protective sleeve that opens wide enough for padded contents without wasted void fill.

Who is it for

Online sellers, warehouse packers and office mailrooms that regularly dispatch long, narrow or softly padded goods—think posters, rolled textiles, tools, or spare parts—and want a paper-based alternative to plastic poly mailers.

Main features

• Gusseted side-fold design expands to accommodate thicker items while keeping a flat profile when empty.
• Made from brown cellulose kraft paper at 32 g/m²: light enough to keep postage low, strong enough for non-abrasive contents.
• No viewing window, so contents stay private and the bag remains fully opaque.
• Natural matte kraft finish accepts labels, stamps and handwritten addresses without smudging.
• Sold as a single piece, ideal for testing or low-volume use.
