The meaning of nanocomposites has widened drastically to enclose an oversized sort of systems like 1D, 2D, 3D and amorphous substances, made from clearly different substances and mixed at the nanometer scale. This research presents an in depth definition of nanocomposites, its origin, classification, properties, benefits, also as its future. With the right choice of compatibilizing chemistries, the nanometer-sized clay platelets interact with polymers in unique ways. The area shows that the appliance possibilities for packaging include food and non-food films and rigid containers. In plastics the benefits of nanocomposites over conventional ones don’t stop at strength. The general class of nanocomposite organic/inorganic materials may be a fast growing area of research. Significant effort is concentrated on the power to get control of the nanoscale structures via innovative synthetic approaches. The characteristics of nanocomposite materials rely not only on the characteristics of their individual parents but also on their morphology and interfacial characteristics. The latter can derive by combining properties from the parent constituents into one material. There is also the likelihood of latest properties which are unknown within the parent constituent materials. Nanocomposites can then be defined as nanomaterials that combine one or more separate components so as to get the simplest properties of every component (composite). In nanocomposite, nanoparticles (clay, metal, carbon nanotubes) act as fillers during a matrix, usually polymer matrix. The inorganic substances are frequently 3D framework systems like zeolites, 2D layered materials like clays, metal oxides, metal phosphates and even 1D and zero-D substances Research work has revealed that usually all types and classes of nanocomposite substances cause new and upgraded characteristics as compared to their macrocomposite equivalents. Finally, lamellar nanocomposites represent an extreme case of a composite during which interface interactions between the 2 phases are maximized. Inorganic layered materials exist in great variety. They have well explained, instructed intralamellar space potentially reachable by foreign matters. This capability allows them to act as matrices for polymers, resulting exciting hybrid nano-composite substances. Lamellar nano-composites are often divided into two distinct classes, intercalated and exfoliated. In exfoliated nano-composites the amount of polymer chains between the layers is nearly continuously variable and therefore the layers stand >100 Å apart. The inserted nano-composites also are more material-like due to the stable polymer/layer ratio, and that they are exciting for their electronic and charge transmission characteristics. On the opposite hand, exfoliated nanocomposites are more interesting for his or her superior mechanical properties. However, Nanocomposites are used commercially since Toyota introduced the primary polymer/clay auto parts because the potential applications transcend automotive industry. One of the foremost promising is drink packaging application considering increased barrier properties of polymer clay nanocomposites. It is easy to know the commercial and technical importance of this field. Currently, progresses within the capability to distinguish, manufacture and alter nanometer-scale materials have caused their higher use as fillers in new types of nanocomposites.
