Double wall cardboard boxes - 430 x 310 x 200mm A3

A3 double wall box: 430 x 310 x 200 mm

Graphic print, technical drawings, posters and art portfolios have one thing in common: they need to stay flat. With internal dimensions of 430 x 310 x 200 mm, this box takes A3 (420 x 297 mm) without any folding or rolling. Since 2007, we have been the go-to wholesaler for cardboard boxes, and we supply this size mainly to printers, architects' practices and online shops selling larger flat products.

With a height of 200 mm and a capacity of about 26.7 litres, there is room for more than a stack of A3: several folders or a good quantity of folded textiles fit too. The boxes come flat-packed in packs of 30 – convenient if you ship regularly and would rather not keep reordering small quantities.

Who is this box for?

Printers and agencies: proofs, posters and A3 catalogues arrive flat and crease-free.
Architects and engineers: drawing sets and project folders safely to clients or the archive.
Artists and photographers: prints and portfolios with a sheet of board in between.
Clothing and textiles: the generous base lets you ship folded garments neatly flat.

Frequently asked questions

Will A3 sheets and folders lie flat inside?

Yes. A3 measures 420 x 297 mm, so with 430 x 310 mm inside you have around 10 mm spare in length and 13 mm in width. A single A3 folder with a slim spine will usually fit too, but do measure folders with a thick spine or rigid cover first.

Do I really need double wall for A3 print?

For a few light sheets, single wall boxes are often enough. A full A3 box of paper soon gets heavy, though, and with such a wide format double wall board stops the base and sides from giving way when lifted and stacked.

How many boxes are there on a pallet?

A pallet holds 8 packs of 30, so 240 boxes in total – a practical quantity for businesses that use this size on a regular basis.
