Beschreibung
Zusammenfassung:	The invention relates to the technical field of high polymer materials, in particular to a high-elasticity antibacterial PETG material, a preparation method and a medical packaging material. The preparation method comprises the following steps: loading nano-silver particles by using graphene oxide to obtain an antibacterial agent, modifying the surface of the antibacterial agent by using 3-aminopropyltriethoxysilane to obtain a modified antibacterial agent, mixing diisocyanate, polyester polyol and hydroxyl-terminated polysiloxane for reaction, and carrying out vacuum drying to obtain the nano-silver-modified polyurethane coating. The preparation method comprises the following steps: adding a modified polyurethane-loaded antibacterial agent, adding a modified antibacterial agent, amoxicillin, a chain extender and a catalyst, carrying out a stirring reaction to obtain a modified polyurethane-loaded antibacterial agent, carrying out melt blending on the modified polyurethane-loaded antibacterial agent, dibutylt
