As nanotechnology establishes, nanofillers will significantly be made use of as active ingredients in a selection of applications. This method is indicated to produce eco-friendly packaging materials and uses a combination of biopolymers. Nanofillers are utilized in the advancement of nanocomposites considering that the applications are the focus. The varied nanofillers loaded the individual qualities required for the applications. Nanofillers enhance the mechanical, thermal, electrical, and chemical attributes of composite products without changing their density. Via the interface polarization, the enhancement of both conducting as well as nonconducting nanofillers alters the dielectric attributes, which subsequently affects many specifications like mobility, columbic possibility, and crystallinity. The four standard subtypes of nanofillers are organic, inorganic, carbon nanostructures, and clays. Inorganic nanofillers consist of metals and metal oxides, whereas organic nanofillers consist of starch, cellulose, lignin. These compounds are totally biodegradable in a wide range of environment, and deterioration or incineration of starch items would recycle atmospheric CO2. Carbon nanostructures consist of graphene, carbon nanotubes (CNTs), fullerenes, and nanofiber.
