The CP 010.05 Rigid All Board Envelope provides strong, dependable protection for medium‑sized flat items that need to stay crease‑free in the post. Made from durable E‑flute corrugated cardboard, it offers the rigidity needed to prevent bending, corner damage and general handling wear.

With external measurements of 260 x 350 mm, this envelope features 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 a practical choice for sending books, catalogues, calendars, artwork, prints, documents and other items that shouldn’t be rolled or folded. The maximum internal size of 250 x 340 x <50 mm* provides useful space while keeping everything securely in place.

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

*Effective internal size reduces as content thickness increases.
