Abstract:

SARAN Polyvinylidene Chloride (PVDC) resins are transparent high barrier plastic materials that, when used in a packaging material, prevent permeability of most gases and chemicals. Additionally, they present the advantage that these barrier properties are not sensitive to humidity. As a consequence, they can form high performance packaging solutions in monolayer or multilayer structures such as SARANEX coextruded multilayer barrier films that will have a predictable barrier level whatever the environment conditions (temperature and humidity) are.

Such barrier properties are particularly suited in applications where packed goods are sensitive to moisture or when water is present inside the packaging. For example, packaging of liquids, fresh meat or cheese; or else packaging of dry foods. Other specific applications where SARAN PVDC resins or SARANEX multilayer high barrier films are recommended are packaging of aggressive chemicals that can either react with moisture in air and form acids or react with material of packaging.
