The CP 010.84 Rigid All Board Envelope is designed to protect smaller flat items that need firm, bend‑resistant packaging. Made from strong E‑flute corrugated cardboard, it provides reliable rigidity to prevent creasing, corner damage and general handling wear during transit. With external measurements of 120 x 235 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 throughout the postal journey. It’s a practical option for sending compact books, catalogues, calendars, artwork, prints, documents and other items that shouldn’t be rolled or folded. The maximum internal size of 110 x 225 x <50 mm* offers useful space while keeping everything neatly 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.
