The purpose of food packaging is to preserve
the quality and safety of the food it contains from the
time of manufacture to the time it is used by the
consumer. An equally important function of packaging
is to protect the product from physical, chemical, or
biological damage (Dallyn & Shorten, 1998). The most
well-known packaging materials that meet these criteria
are polyethylene- or co-polymer based materials, which
have been in use by the food industry for over 50 years.
These materials are not only safe, inexpensive,
versatile, but also flexible (Tice, 2003). Within the plastic
packaging market, food packaging is the largest
growing sector (Comstock et al., 2004). However, one
of the limitations with plastic food packaging materials
is that it is meant to be discarded, with very little being
recycled.
