Description
A thermoplastic polymer that is commonly called saran. Polyvinylidene chloride forms films that are impermeable to vapors, moisture, and oxygen. It is most often used as a barrier film for packaging.
See also saran film.
Synonyms and Related Terms
poly(vinylidene chloride); PVDC; poli(cloruro de vinilideno) (Esp.); chlorure de polyvinylidène (Fr.); polivinilidene cloruro (It.); cloreto de polivinilideno (Port.)
Examples: saran; Cryovac
Other Properties
Burns with green flame producing pungent odor and evolving HCl.
Turns yellow or brown when exposed to alkalis.
