The CP 010.01 Rigid All Board Envelope is a strong and practical choice for sending smaller flat items that need firm, bend‑resistant protection. Made from durable E‑flute corrugated cardboard, it provides the rigidity needed to keep contents flat and secure throughout the postal journey.

With external measurements of 160 x 260 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 sending books, catalogues, calendars, artwork, prints, documents and other items that shouldn’t be rolled or folded. The maximum internal size of 150 x 250 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 clean, simple opening experience with the integrated tear strip.

*Effective internal size reduces as content thickness increases.
