Most recycled or biodegradable polymers have poor mechanical and thermal properties. Therefore they are widely used as films or disposable products rather than in products that require strong properties. Antibacterial properties especially are one of the most required properties when used as a film or as a medical disposable product. The zinc metal compounds are widely used among various antibacterial agents. The recycled film pellet and Poly-Butylene Adipate Terephthalate (PBAT) are investigated as polymer matrixes. Antibacterial agent is Zinc Pyrithione (ZnP), which is industrially approved by the European Biological Regulation (EU-BPR). Antibacterial activity was measured through film adhesion (JIS Z2801), shaking flask (ASTM E 2149), and turbidity analysis. The fracture surfaces of ZnP compounds were photographed by SEM to confirm the dispersibility of ZnP. As a result of these results, the lowest content of antibacterial agents was determined and changes in thermal stability were confirmed by TGA.
