E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont company. While cellophane was invented in Switzerland, it was not until DuPont acquired the patent in 1923 that allowed DuPont scientist William Hale Charch (1898-1958) to improve it so that it was impervious to water vapor. DuPont produced cellophane until 1986. This collection consists of undated photographs, one saleman's album, and one poster that all relate to cellophane packaging.
