The first synthetic plastic was created in 1907 by chemist Leo Baekeland, who called this liquid resin Bakelite. By the 1920s, the plastic craze was in full gear. By 1939, petroleum companies were introducing nylons. In the 1940s and 50s, polyvinyl chloride (PVC), plastic wrap and nonstick surfaces were developed.
