Question: are rishi tea bags plastic?
Answer: Rishi Tea's certified organic teas are bagged with PLA—polylactic acid, creating “silken” bags. Unlike other “silky” bags, which can be made with PET plastic, these are corn and potato starch-based. ... Once filled, the bags are crimped and sealed with 100% cotton string. No staples, plastics, or glue are ever used.”
