Abstract:

Most of food packaging is mainly petroleum based, trhough plastic precisely. These plastics bring many benefits such as protection, transportation and increasing the shelf life of food. Thus, plastic gained popularity over the years increasing its production and becoming the standard for food packaging. However, there are increasing concerns about its usage and the disposal due to the accumulation in natural habits.This lecture will discus the production of biodegradable food packaging using the same technologies as for plastic packaging, particularly we will discuss blown extrusion. It will contrast the laboratory production (casting technique) vs. extrusion and offer a comparison from a point of view of mechanical properties of the packaging. As applications, it will focus on fruit and vegetables.
