The present invention relates to a biodegradable functional plastic bag and a method of manufacturing the same. The biodegradable functional plastic bag is manufactured by using one or two or more biodegradable polymer resins selected from polyvinyl alcohol (PVA), polyaniline (PANI), polycarbonate (PC), polyethyleneglycol (PEG), polytrimethylene terephthalate (PTT), polyhydroxyalkanoate (PHA), polycaprolactone (PCL), poly (glycolic acid) (PGA), polyethylene oxide (PEO), poly-hydroxy butyrate (PHB), and polydioxanone (PDO). In addition, a natural functional composition is added to the biodegradable polymer resins to provide an antibacterial function, anion/far infrared radiation functionality and an aroma diffusion function of a plastic bag, thereby maintaining a clean state, providing an effect beneficial to a human body such as a blood circulation and the like, and allowing a user to maintain a pleasant feeling by diffused aroma. 본 발명은 폴리비닐알콜(polyvinyl alcohol, PVA), 폴리아닐린(polyaniline, PANI), 폴리카보네이트(polycarbonate, PC), 폴리에틸렌글리콜(polyethyleneglycol, PEG), 폴리트리메틸렌테레프탈레이트(Polytrimethylene terephthalate, PTT), 폴리하이드록시알카노에이트(Polyhydroxyalkanoate, PHA), 폴리카프로락톤(Polycaprolactone, PCL), 폴리글리콜산[Poly(glycolic acid), PGA], 폴리에틸렌옥사이드(polyethylene oxide, PEO), 폴리히드록시부틸레이트(poly-hydroxy butyrate, PHB), 폴리다이옥사논(polydioxanone, PDO) 중 선택되는 어느 1종 또는 2종 이상의 생분해성 고분자 수지를 이용하여 비닐봉투를 제조하되, 상기 생분해성 고분자 수지에 천연기능성 조성물을 첨가하여 비닐봉투의 항균성, 음이온원적외선 방사 기능성 및 향 발산 기능을 제공함으로써 청결한 상태를 유지시켜 주고, 또한 혈액 순환 등 인체에 유익한 효과를 제공하며 향 발산에 의한 상쾌한 기분이 유지될 수 있도록 하는 생분해 기능성 비닐봉투 및 이의 제조방법에 관한 것이다.
