Strong Board, Lightweight: What Your Box Is Made Of
Strength starts with the sheet, so a custom cardboard shipping box uses a rippled layer called a flute to soak up bumps and drops. We use right board to keep your boxes light for low postage and tough enough to protect products from the warehouse shelf to the front door.
