Color print advertisement for Saran, the trade name for polyvinylidene chloride, which can be formed into monofilaments or a thin plastic film. The advertisement shows a coiled length of plastic tubing made from Saran against a blue background. Lines emanate from the open end of the tubing and connect to smaller illustrations showing the uses of Saran tubing. The accompanying text describes the advantages of plastic tubing in lieu of metal piping, especially plastic's stability at temperature extremes and resistance to chemicals. Notably, the advertisement was produced during World War II and bears the Company's wartime tagline "Dow: Chemicals Indispensable to Industry and Victory."
