Packaging Design Zhengyuanpu Pu'er Tea Packaging by Jinde Design Zhengyuanpu Travellers Series is a portable packaging design for Pu'er tea, a traditional Chinese drink. Pu'er tea is usually sold as pressed cakes of 357 grams, which must be pried open with a tea pin before brewing. The Travellers Series holds a small portion instead, so no tools are needed and the wrapper is simply torn open. Each wrapper measures 50 by 85 by 3 millimetres and is made of cotton paper. Embossing, debossing and foil stamping shape the tea image and suit the taste of the intended consumers. Safer materials and a simpler production process were selected.
