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.
