Researchers have been focusing on development of new materials as well as new coating processes on materials
suitable for food packaging for quite some time but there has been no ideal material which is available to protect the
food stuff from microbial attack. With the advent of nanotechnology, it is expected that it can provide not only
innovative solutions to increase the performance of the polymers but can also provide safety, economical and
environmental advantages [1-3]. The packaging films with nanoparticle coating have shown great potential to
control growth of food borne pathogens. Hydroxypropyl methylcellulose (HPMC) is a biopolymer used as a binder
has the ability to help in formation of good and uniform films from thermally induced gelatinous coatings [4],
allowing their use as materials to retard oil absorption in deep frying food products [5]. These coated films on
coming in contact with food stuff, act upon food-born microorganisms and inhibit their growth. These agents belong
to a wide spectrum of organic/inorganic compounds, essential oils, bacteria originated antibacterial proteins
(bacteriocins), enzymes, fruit extracts etc. These antibacterial films have shown great potential in inhibiting
microbial growth in food stuff. However, the development of new resistant strains of bacteria to current antibiotics
has led to the search for new bactericides that can effectively reduce the harmful effects of microorganisms.
