Specific polymer blends of polylactic acid (PLA) and polyhydroxybutyrate (PHB) and poly-(butylenes adipate-co-terephthalate (PBAT) as a fatty acid quaternary ammonium modified clay. The blends are particularly useful for barrier packaging.

Biodegradable polymeric nanocomposite compositions particularly for packaging

A method and device (10) for removing oxygen using a reduced oxidase enzyme and for providing a calorimetrically detectable signal of the presence of the oxygen. A reduced laccase or ascorbate oxidase is preferably provided with a substrate which reduces the oxidase. Color is generated which can be detected visually or by other means such as a spectrophotometer. The method and device are particularly useful in the food, pharmaceutical and biological industries.
