Antimicrobial substances incorporated into packaging
materials can control microbial contamination by reducing
the growth rate and expansion of the lag phase of the target
microorganism, or by inactivation of microorganisms by
contact.Inclusion of GRAS, non-GRAS and natural antimicrobials,
such us metal nanoparticles (silver, gold and
zinc), metal oxide nanomaterials and carbon nanotubes,
into plastic matrix intend their slowly migration on the
product surface and inhibition of the growth of microorgan-
isms, increasing the shelf life and safety of the product
(Silvestre, Duraccio, & Cimmino, 2011).
