Due to the recent COVID-19 incident, several products using antibacterial substances are widely used in real life, but some antibacterial substances that are not biologically decomposed pollute the environment. In this study, we decided to manufacture an antibacterial film by extracting a material called trans-cinnamaldehyde in cinnamon. After extraction, HPLC and IR were used to verify whether this antibacterial material was extracted. As a result, it had a concentration of about 666.93 μg/ml. The antibacterial properties of the t-cinnamaldehyde extracted through the disk diffusion method using E. coli and the antibacterial film using the extracted solution were verified. The extracted t-cinnamaldehyde had an antibacterial radius of 1.08 cm, and the antibacterial radius of the antibacterial film using the extracted solution was 0.21 cm. The rupture strength was measured to verify the durability of the synthesized film, and it was confirmed that the film was stronger than copper films
