The food products are preserved by maintaining it in an inert and low oxygen atmosphere for inhibiting
microbial growth and spoilage, thus the material used should be impermeable to gases. Nanocomposites are
incorporated in the polymer matrix of the substances due to their large surface area which favors the fillermatrix
interactions and its performance. Also the nanoreinforcement’s acts as small, barriers for gases by
complicating the path of the material, both are known as polymer nanocomposites .Nanoclays are composite
