Bio-nanocomposites for food packaging applications

Show Summary Details


Reduction of packaging waste has been a strong motivation for replacing plastic packaging materials by biodegradable materials from renewable sources during the last decades. The efficiency of biopolymer films in food packaging has however been limited by their poor mechanical properties and by their moisture sensitivity. Improving the barrier and tensile properties is a major challenge that has directed the focus towards nanotechnology and the potential of forming bio-nanocomposites by incorporation of nanosized reinforcing fillers in biopolymer matrices. This chapter summarizes some requirements set on food packaging, and deals with legislation concerning materials in contact with packaged food as well as properties of novel biobased nanocomposites with the potential to be utilized in food packaging applications.

Keywords: packaging; renewable resources; moisture sensitivity; reinforcement
