The demand for biobased materials for various end-uses in the bioplastic industry is substantially growing due to increasing awareness of health and environmental concerns, along with the toxicity of synthetic plasticizers such as phthalates. This fact has stimulated new regulations requiring the replacement of synthetic conventional plasticizers, particularly for packaging applications. Biobased plasticizers have recently been considered as essential additives, which may be used during the processing of compostable polymers to enormously boost biobased packaging applications. The development and utilization of biobased plasticizers derived from epoxidized soybean oil, castor oil, cardanol, citrate, and isosorbide have been broadly investigated. The synthesis of biobased plasticizers derived from renewable feedstocks and their impact on packaging material performance have been emphasized. Moreover, the effect of biobased plasticizer concentration, interaction, and compatibility on the polymer properties has been examined. Recent developments have resulted in the replacement of synthetic plasticizers by biobased counterparts. Particularly, this has been the case for some biodegradable thermoplastics-based packaging applications.

在绿色包装应用中用于可堆肥聚合物的生物基增塑剂的发展：综述

由于人们对健康和环境问题的认识不断提高，以及邻苯二甲酸盐等合成增塑剂的毒性，生物塑料行业对各种最终用途的生物基材料的需求正在大幅增长。这一事实激发了新的法规，要求替代合成的传统增塑剂，特别是在包装应用中。生物基增塑剂最近被认为是必不可少的添加剂，可在可堆肥聚合物的加工过程中使用，以极大地促进生物基包装应用。环氧化大豆油、蓖麻油、腰果酚、柠檬酸盐和异山梨醇衍生的生物基增塑剂的开发和利用已得到广泛研究。已经强调了源自可再生原料的生物基增塑剂的合成及其对包装材料性能的影响。此外，还研究了生物基增塑剂浓度、相互作用和相容性对聚合物性能的影响。最近的发展导致合成增塑剂被生物基对应物取代。特别是，一些基于可生物降解热塑性塑料的包装应用就是这种情况。
