Product Highlights
A3 format for documents and prints
Internal dimensions are chosen so A3 sheets, posters and product boxes sit flat without being crushed or overly loose. This makes each A3 mailing box style perfect for shipping artwork, presentation packs and bulk A3 paper.
Compatible A3 Mailing Box With Every Size
Box sizes are aligned with mailing and parcel box brackets, similar to BX4/BXP4 A3‑style cartons. Our A3 mailing box compatible carton helps you stay within size and weight guidelines for Parcel Post and Express services.​
How it works
- Packaging engineers design a box layout in CAD around the product dimensions and required features (locks, windows, inserts, display panels).​
- A steel‑rule die is built to match this layout and mounted on a die‑cutting press.​
- Printed or plain cardboard sheets are fed through the press, where the die cuts the outline and creases fold lines in one pass.​
- Waste is stripped away, leaving flat die‑cut blanks that are shipped flat and later folded into finished boxes at packing.​
