Cellophane is a thin, transparent, waterproof, protective film that is used in many types of packaging. It was invented in 1908 by Jacques Edwin Brandenberger, a Swiss chemist. He had originally intended cellophane to be bonded onto fabric to make a waterproof textile, but the new cloth was brittle and not useful. Cellophane proved very useful all alone as a packaging material. Chemists at the Dupont company (who later bought the rights to cellophane) made cellophane waterproof in 1927.
