Claim 0:
1. An antibacterial and antifungal polyester material, comprising:
a substrate film comprising a polyester resin material; and
a plurality of functional polyester masterbatch granules comprising a polyester resin matrix material, dispersed in the substrate film
wherein each of the functional polyester masterbatch granules includes
an antibacterial and antifungal additive that includes
a plurality of glass beads disposed in the polyester resin matrix material, and
a plurality of silver nanoparticles distributed on an outer surface of the glass beads,
 wherein the plurality of silver nanoparticles do not agglomerate with each other;

wherein film substrate has a thickness of between 0.125 centimeters (cm) and 0.50 centimeters, and each of the glass beads has a particle size of between 3 micrometers and 10 micrometers;
wherein, based on a total weight of the antibacterial and antifungal polyester material being 100 wt. %, a content range of the polyester resin material of the substrate film is between 80 wt. % and 98 wt. %, and a content range of the functional polyester masterbatch granules is between 2 wt. % and 20 wt. %;
wherein, in each of the functional polyester masterbatch granule, a weight ratio range of the polyester resin matrix material relative to the antibacterial and antifungal additive is ranging from 70 to 99: 1 to 30;
wherein a content range of the plurality of silver nanoparticles in the antibacterial and antifungal polyester material is between 0.1 wt. % and 5.0 wt. %.
