The CP 010.07 Rigid All Board Envelope is a strong, reliable option for sending larger flat items that need to stay protected and crease‑free in the post. Made from durable E‑flute corrugated cardboard, it offers excellent rigidity to prevent bending, corner damage and general handling wear.

With external measurements of 300 x 410 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 transit.

It’s well‑suited for books, catalogues, calendars, artwork, prints, posters and other items that can’t be rolled or folded. The maximum internal size of 290 x 400 x <50 mm* provides generous space while keeping everything securely 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.
