Plastics and their mass production have irreversibly caused problems for the earth's environment, to the point that plastics seriously threaten the survival of human beings and other species. Pu'er tea brand Wuxi Tea has launched a tea product packaged in environmentally friendly, biodegradable and ecologically-recycled plant material, a first for the brand. This ecological material is made of bagasse and wheat straw plant fiber, naturally clean materials with good air permeability. This green packaging also helps with the natural fermentation and transformation of Pu'er tea.
