中文摘要:
      目的 根据生物降解材料聚乳酸(PLA)的生产、性能和改性方法探索其在包装领域的应用,为后续的改性研究提出可能的应用方向。方法 介绍PLA的原料、生产方法、生产现状及在包装领域的应用现状,分析包装对PLA的降解性、阻隔性、力学性能、光学性能、热性能、抗菌性能、导电性和压电性等方面的要求和相关改性方法的研究进展。结果 PLA材料在包装领域有很好的应用前景,但在韧性、抗菌性、导电性等方面还不够完善,当应用于对这些性能有较高要求的运输包装、抗菌包装和智能包装时需进一步改进。结论 在保留PLA透明、可降解的优势性能前提下,还可以进一步提高其可控制降解、韧性、耐热性、阻隔性、导电性等,并降低生产成本,使之在包装领域的应用更广泛。
英文摘要:
      The work aims to study the application of PLA in the packaging field according to the production, property and modification methods of polylactide acid (PLA), so as to put forward possible application direction for further modification researches. The raw materials, production methods, production status and application status of PLA in the packaging field were introduced and requirements of packaging for PLA degradation, barrier, mechanical properties, optical properties, thermal properties, antibacterial properties, electrical conductivity and piezoelectric properties, and the modification development on modification were analyzed. PLA materials had good application prospects in the field of packaging. However, the toughness, antibacterial property, conductivity and other aspects were not perfect and required to be improved when used in some packaging areas with higher requirements, such as transport packaging, antibacterial packaging and intelligent packaging. On the premise of maintaining PLA's transparent and degradable properties, the controllable degradation, toughness, heat resistance, barrier, conductivity of PLA can also be improved further to reduce the production so that PLA can be used widely in the packaging field.
