New trend material for food packaging = Nanoclay! http://www.adhesivesmag.com/articles/93605-breaking-packaging-barriers-with-oxygen-barrier-coatings Food packaging plays a vital role in preserving food throughout the distribution chain. A package provides protection, resistance, and special physical, chemical, or biological needs. In recent years, the development of novel food packaging (modified atmosphere & active packaging) has increased the shelf life of foods. Moreover, their safety and quality has increased parallely. Nanotechnology offers several advantages to food packaging industry. For example, barrier resistance, functional performance increase with nanotechnology. A recent trend is to use nanocomposites materials for food-packaging applications. Nanoclay is one the most popular material used in food packaging industry. Small plate-shaped particles of clay, 1nm thick and 1,000nm in diameter. These tiny partciles are embedded into the plastics normally used for packaging, such as polypropylene and polyethylene. It provides longer shelf life It improves high temperature performance It provides flexible packaging It provides several functionalty such as anti-temper, ant-microbial, self-repair sensor It provides good gas barrier, oxygen barrier, films Nanotech packaging is not currently used in the most part of the Europe, but is used in the America and other parts of the world. This type of packaging could be particularly useful and advantageous in the developing world, where food spoilage is a major issue.
