Saran
Saran is the registered trademark of Dow Chemical for products made from polyvinylidene chloride (PVdC) and copolymers of vinylidene dichloride , especially with vinyl chloride .
Saran is available as a barrier film and as a granulate for extrusion . PVdC or Saran is an excellent barrier material for oxygen and water vapor.
PVdC was developed by Dow by John J. Grebe and was initially used for a seawater-proof protective film for aircraft of the US armed forces. The initially strong odor and the greenish color prevented other applications.
After these properties were eliminated, the product could also be used for films even in the food sector (e.g. cling film ). Saran has food approvals according to FDA Regulation 21 CFR and complies with EU Directive 2002/72 / EU.
Coextruded multilayer film with PVdC bears the Dow trade name Saranex .
The adhesive household film brand SaranWrap, which is primarily known in the Anglo-American region , is now marketed by SC Johnson & Son .
