“…Moreover, this technology shows some advantages compared to coatings, while beside the improvement of mechanical properties, the introduction of stability of NPs-additives incorporation without possible migration in media, which is especially appreciated in packaging. The clay-based nanoadditives [ 10 , 11 , 12 , 13 , 14 ], nanocellulose [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ], carbon nanotubes [ 23 , 24 , 25 ], silica NPs [ 26 ], metal and metal oxide NPs [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ] which, within the PLA matrix, represent one of the widely studied solutions for the preparation of multifunctional PLA nanocomposites, improving physicochemical, mechanical properties as well as providing thermal and additional antibacterial efficacy and protection of the [ 37 , 38 , 39 , 40 , 41 , 42 ]. In general, the modification of PLA-based NPs composites (PLA-NPs) represents a key strategy for the advantage of maintenance-free sterile surfaces, which are aimed at many plastic products [ 39 ].…”
