The CP 010.08 Rigid All Board Envelope offers dependable protection for medium‑to‑large flat items that need to stay perfectly flat in the post. Made from sturdy E‑flute corrugated cardboard, it provides the rigidity needed to prevent bending, creasing or corner damage during handling and delivery.

With external measurements of 350 x 510 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 overall protection.

It’s a practical choice for sending books, catalogues, calendars, artwork, prints, posters and other items that can’t be rolled or folded. The maximum internal size of 340 x 500 x <50 mm* offers 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.
