Saran (plastic)

（重定向自Saran fiber）

Saran is the trade name for a number of polymers made from vinylidene chloride (especially polyvinylidene chloride or PVDC), along with other monomers. Since its accidental discovery in 1933, Saran has been used for a number of commercial and industrial products. When formed into a thin plastic film, the principal advantage of Saran, when compared to other plastics, is its very low permeability to water vapor, flavor and aroma molecules, and oxygen. This oxygen barrier retards food spoilage, while the film barrier to flavor and aroma molecules helps food retain its flavor and aroma.
