Abstract: A food contact safe, germ repellent plastic selected from modified thermoplastic, vulcanized silicone rubber or modified base plastic. The plastic includes an anti-biofouling agent at approximately 1 to 20 wt. % to the total weight of the plastic; and one or more components of fillers, carrier agent, mold releasing agent, curing agent, and/or oil, at approximately 0.1 to 2 wt. % for each or more of the components to the total weight of the plastic, where the anti-biofouling agent forming a hydration layer on the plastic imparts germ repellency against bacteria including Escherichia coli and Staphylococcus aureus while optical and mechanical properties including transmittance, tensile strength, impact strength, hardness, and/or heat deflection temperature of the plastic is/are changed by less than 10% after being associated with the anti-biofouling agent and the one or more of the components other than the anti-biofouling agent.
