Bacteria repellent material safe to contact with food

The invention provides antibacterial plastic safe in food contact. The antibacterial plastic is selected from modified thermoplastic plastic, vulcanized silicone rubber or modified basic plastic. The plastic includes an anti-biofouling agent accounting for about 0.1 to 20 wt% of the total weight of the plastic; and one or more of a filler, a carrier agent, a release agent, a curing agent and/or an oil component, each of which accounts for about 0.1 to 2 wt% of the total weight of the plastic, where the anti-biofouling agent forms a hydrated layer on the plastic such that it is repellent against bacteria including Escherichia coli and Staphylococcus aureus, the optical and mechanical properties of the plastic, including light transmittance, tensile strength, impact strength, hardness and/or heat distortion temperature, change by less than 10% after combination with the anti-biofouling agent and one or more other components other than the anti-biofouling agent. 本发明提供一种食品接触安全的斥菌塑料，选自改性热塑性塑料、硫化硅橡胶或改性基础塑料。该塑料包括防生物
