摘要
聚乳酸(polylactic acid,PLA)作为一种可降解的生物基材料,因其良好的生物降解性和环境友好性在食品包装领域展现出巨大潜力。然而,PLA的耐热性、韧性和阻隔性限制了其应用。因此,通过物理和化学方法对其进行改性,以提高PLA的性能,使其满足肉类包装的需求。本文详细讨论改性PLA的物理及化学改性方法,以及在肉类包装中的气体阻隔性、抗菌性和机械性能等方面的应用。
Polylactic acid(PLA)is a biodegradable bio-based material that has shown great potential in the field of food packaging due to its excellent biodegradability and environmental friendliness.However,PLA has limitations in terms of heat resistance,toughness and barrier properties,restricting its application.Therefore,physical and chemical modifications have been employed to enhance the performance of PLA to make it suitable for meat packaging.This paper provides a detailed discussion on the physical and chemical modification methods of PLA,as well as its application in meat packaging by virtue of gas barrier properties,antibacterial properties and mechanical performance.
