A3 printer boxes

(7 products)

Ship larger brochures and posters securely with our A3 printer boxes

Our range of A3 printer boxes are specially designed for shipping and storing larger A3 sized products. For posting posters, or brochures choose our standard single wall boxes with a sealable flap that protects the contents and pre-scored sides for easier folding. If you need extra protection, try our double wall boxes that are crush-resistant and ideal for stacking or storage.

Our telescopic A3 boxes are a good idea if you need to ship or store products of different weights and sizes. These flexible boxes eliminate the need for extra void fill and fit snugly to products of any thickness. To find the right printer boxes for your products, simply call our in-house packaging specialists.

An A3 sized print measures 420mm x 297mm.

Find the right sized box from a choice of over 900!
