During production, saran film passed through a series of rollers, which deflated the bubbles and prepared the film for winding on rolls. Initially developed for the U.S. Army to wrap arms and equipment for transport during World War II, saran plastic was subsequently developed and marketed as Saran Wrap for household use.
