It is crucial to find an effective, environmentally acceptable solution, such as bioplastics or biodegradable plastics, to the world's rising plastics demand and the resulting ecological destruction. This study has focused on the environmentally friendly production of bioplastic samples derived from corn starch, rice starch, and tapioca starch, with various calcium carbonate filler concentrations as binders. Two different plasticizers, glycerol and sorbitol, were employed singly and in a rich blend. To test the differences in the physical and chemical properties (water content, absorption of moisture, water solubility, dissolution rate in alcohol, biodegradation in soil, tensile strength, elastic modulus, and FT-IR) of the produced samples, nine samples from each of the three types of bioplastics were produced using various ratios and blends of the fillers and plasticizers. The produced bioplastic samples have a multitude of features that make them appropriate for a variety of applications. The test results show that the starch-based bioplastics that have been suggested would be a better alternative material to be used in the packaging sectors.
找到一种有效且环境可接受的解决方案，如生物塑料或可生物降解塑料，以应对全球不断增长的塑料需求及其导致的生态破坏，这至关重要。本研究聚焦于以玉米淀粉、大米淀粉和木薯淀粉为原料，添加不同碳酸钙填料浓度作为粘合剂，进行生物塑料样品的环保生产。单独使用并以丰富混合物形式使用了两种不同的增塑剂，甘油和山梨醇。为测试所生产样品的物理和化学性质（含水量、吸湿率、水溶性、在酒精中的溶解速率、在土壤中的生物降解、拉伸强度、弹性模量和傅里叶变换红外光谱）的差异，使用填料和增塑剂的不同比例及混合物，从三种生物塑料中的每种制备了九个样品。所生产的生物塑料样品具有众多特性，使其适用于各种应用。测试结果表明，所建议的基于淀粉的生物塑料将是包装行业中更好的替代材料。
