The Largest Mail Tuff, Big Enough For A3 Work Laid Flat

MT7 is the top of Polycell's Mail Tuff chart at 360 x 485mm with a 50mm flap, packed 50 to a carton, for oversized items that still suit a light padded bag rather than a box.

A3 posters, art prints, architectural drawings and school artwork can go in without folding, with space for a sheet of card behind them to keep them flat. The same bag takes bulky soft goods too: a folded towel set, a bundle of uniforms, a cushion cover or a stack of printed tote bags.

Polycell's construction is consistent across the range, with kraft paper on the outside laminated to a bubble lining and LDPE as the main material. Their stated goals are low postage weight, surface protection for the contents and resistance to knocks through the general mailing cycle, backed by a tamper-evident seal on the flap. Because the carton holds 50 rather than 100, it takes up less room in a small dispatch area.

Look through the Polycell range, packing cartons for heavier parcels, and labels and tags.

FAQs

Polycell list 50 mailers per carton for MT7, the largest size, where the smaller sizes run to 100 or 300. Our listing is that full carton.
Yes. An A3 sheet is smaller than the mailer in both directions, so prints and drawings go in unfolded. Add a piece of card behind them if they must stay perfectly flat.
No. MT7 is the largest size on Polycell's Mail Tuff chart. For bigger soft goods, the Polycell courier bags come in larger sizes.
Polycell's Corrugated Mailer comes in the same 360 x 485mm measurement with a 50mm flap, also 50 to a carton, and Polycell list kraft paper as its main material.
