The CP 010.06 Rigid All Board Envelope is a dependable choice for sending medium‑sized flat items that need firm, bend‑resistant protection. Made from strong E‑flute corrugated cardboard, it provides the rigidity needed to keep contents flat and secure throughout the postal journey.

With external measurements of 260 x 370 mm, this envelope includes pre‑creased folds that allow the depth to be adjusted up to 50 mm. This makes it easy to tailor the fit to the contents, helping to reduce movement and improve protection during handling and delivery.

It’s ideal for books, catalogues, calendars, artwork, prints, documents and other items that shouldn’t be rolled or folded. The maximum internal size of 250 x 360 x <50 mm* offers practical space while keeping everything neatly in place.

Packing is quick and tidy thanks to the peel‑and‑seal closure, and customers benefit from a simple, frustration‑free opening experience with the integrated tear strip.

*Effective internal size reduces as content thickness increases.
