Abstract
Composite system comprises: (A) a base material containing organic materials; and (B) an aroma- or odour-barrier layer consisting of an organically-modified silicic acid polycondensate or hetero-polycondensate. USE - The composite is used as a packaging material (e.g. film, sheet or hollow mouldings) for e.g. food, drugs, chemicals, and in technical applications, e.g. as membrane or protective layer for sensors. ADVANTAGE - The composite system has a very good barrier action against aromas and odour substances, even in presence of moisture. Layer (B) can also act as a multi-functional barrier, e.g. against odour substances and against oxygen. It shows good adhesion to various organic substrates and provides extra mechanical stability and wear resistance to the substrate surface. The system can be used as a lightweight, transparent substitute for glass or metal in various packaging applications.
