Nanotechnologies. Polymeric nanocomposite films for food packaging with barrier properties. Specification of characteristics and measurement methods
| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 28 |
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.
This document addresses neither safety and health issues related to the food packaging nor environmental aspects.
