초록

In this study, a biodegradable packaging film was developed using two marine algae, Gelidium amansii, and Sargassum horneri. The chemical properties and microstructure of the developed film were evaluated using field emission scanning electron microscope, Fourier transform infrared spectroscopy, gas chromatography-Mass spectroscopy, and thermogravimetric analysis. Furthermore, the mechanical properties and toxicity of the film were evaluated using the ISO 1924 and IEC 62321 methods, respectively. The biodegradability of the film was evaluated according to ISO 14855-1:2012 method. The film was primarily made of cellulose and had biodegradability that was about 17 times greater than that of PBS, a representative eco-friendly plastic.
Moreover, the mechanical properties improved by approximately 40% compared to the seaweed-based film of the previous study. The virulence test revealed that the content of all of the toxic substances listed in IEC62321 was below the measurement limit.
An egg carton that can be used in practice was manufactured in accordance with ISO 534, and its applicability was tested using the biodegradable packaging film prepared.
