Abstract

Polymer packaging nanocomposite is becoming more common as a packaging technology for maintaining food quality and safety and prolonging the shelf life of packaged foods. This chapter illustrates the characterization of prepared nanocomposite films used for food packaging applications. A scanning electron microscope (SEM) and transmission electron microscope (TEM) are used to investigate the microstructure and surface morphology of polymer nanocomposites. The TEM enables a qualitative assessment of nanofillers within the polymer matrix for their distribution, internal structure, and dispersion. Energy-dispersive X-ray spectroscopy (EDX) can be used to evaluate a film’s chemical composition. A variety of polymer nanocomposites can be characterized by XRD by checking their crystallinity, crystallite size, and structure. Fourier transform infrared spectroscopy (FTIR) determines the chemical and functional changes caused by polymer and nanofiller interactions.
