This document specifies characteristics including barrier properties to be measured of polymeric nanocomposite films used for improving food packaging. The barrier properties cover gas (oxygen), water vapour transmission and UV-Vis light transparency. This document also describes the relevant measurement methods.<\/p>\n

This document addresses neither safety and health issues related to the food packaging nor environmental aspects.<\/p>\n
