New packaging technologies are developed as response to consumer demands and industrial production trends to well-preserved, fresh, delicious and practical products with extended durability and controlled quality. In order to extend the shelf life of any type of packaged food, it is necessary to continually develop the properties of packaging materials. Nanotechnology has shown many advantages in various areas, including in the field of food packaging industry. Requirements for the appropriate gaseous and vapor-proof polymer material, good barrier and mechanical properties of the polymer and some advanced packaging properties have intensified interest in the development of new technologies. The development of polymeric materials in combination with appropriate nanfillers and new forms of nanocomposite formulation, have great potential in the application of different types of packaging. The use of nanocomposites in food packaging can pose a risk to consumers due to particulate matter that can migrate from nanomaterials to the product. It is therefore necessary to check the scope of migration of nanoparticles from food packaging and the development of methods to prevent such migration.
