Polyethylene terephthalate (PET) is a thermoplastic polymer from polyester family which enjoys very good mechanical and tensile strength. This polymer is used for producing plastic bottles and disposable tableware but its main usage is for production of yarn in textile industry. Masterbatch is a solid or liquid additive for plastic used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). This material can be used as an antibacterial plastic besides taking advantages of its especial mechanical properties. The most frequently used approach to prepare antibacterial plastics is to include various organic or inorganic substances, such as tea extract, chitosan, copper, silver, zinc, etc. in polymer matrices. Nanoparticles are being used industrially for modifications to plastics. A common feature is their antibacterial activity. The antibacterial activity of them has been demonstrated against human pathogenic bacteria, mainly E. Coli and S. aureus.
