Climate change and increased pollution caused by traditional petrochemical plastics made the biodegradable environment-friendly plastic (bioplastic) research more popular. Bioplastics can be manufactured from natural renewable ingredients and used as food packaging material without harming the environment. This research work focuses on developing bioplastic films from natural ingredients such as starch of tamarind seeds, and berry seeds, with licorice root. Attention has been paid to characterizing the material by biodegradability, mechanical testing, Fourier Transformed Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), antimicrobial analysis tests. Phenolic compounds present in the berry seeds starch increased the soil biodegradability as well as the mechanical and thermal properties of the bioplastic films. The FTIR spectra confirmed the presence of various bio-molecules. Improved antimicrobial performance is also obtained. The results of this research confirm that the prepared bioplastic samples can be used in packaging applications.
气候变化以及传统石化塑料造成的污染加剧，使得可生物降解的环保塑料（生物塑料）研究愈发受到欢迎。生物塑料可由天然可再生成分制成，并用作食品包装材料而不损害环境。这项研究工作专注于用罗望子种子淀粉、浆果种子等天然成分以及甘草根来开发生物塑料薄膜。已关注通过生物降解性、力学测试、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、热重分析（TGA）、差示扫描量热法（DSC）、抗菌分析测试来对材料进行表征。浆果种子淀粉中存在的酚类化合物提高了生物塑料薄膜的土壤生物降解性以及力学和热性能。FTIR光谱证实了各种生物分子的存在。还获得了改善的抗菌性能。这项研究的结果证实，所制备的生物塑料样品可用于包装应用。
