Abstract

Nanocomposites, a fusion of traditional food packaging material with nanoparticles are gaining active interest in food packaging sector. In addition to its remarkable antimicrobial spectrum, it displays great mechanical performance and tough resistant characteristics (Montazer and Harifi, 2017). Nanocomposites are usually made up of a polymer matrix in a continuous or discontinuous phase (Arora and Padua, 2010). It is a multiphase material resulting from the amalgamation of matrix (continuous phase) and a nano-dimensional material (discontinuous phase). Based on the nano-material, the nano-dimensional phase is generally characterized into nanospheres or nanoparticles, nanowhiskers or nanorods, nanotubes and nanosheets, or nanoplatelets.
The use of nanotechnology to cover the injection molds works to treat the filling part of the molten resin, and it also creates challenges for packages with relatively complex designs, ease and speed of manufacturing processes, and facing the high prices of raw materials for molds and resin, and a nanometer is known to be 1 billionth of a meter and is used in some measurements visible only by Very high magnification. For example, a sheet of paper is 100,000 nanometers thick, and a person’s hair can reach 50-180,000 nanometers, and there are 25,400.00 nanometers per inch.
