The concept of the envelope dates back to ancient times, with the earliest evidence found in Babylonian clay tablets encased in a thin layer of clay. Paper envelopes, as we know them today, originated in China during the Song Dynasty (960-1279 AD), where they were used to store monetary gifts. By the 17th century, envelopes began appearing in Europe, enhancing the letter-writing process.
