Paper and cardboard
Paper is one of the oldest materials used for packaging. There is evidence that during the Tang Dynasty in China, it was even used to make tea bags! Paper is made by compressing a thin layer of cellulose-containing fibers. The first machine for paper bags production was invented in 1868 by the American inventor Margaret Knight
