Abstract Active natural antibacterial blend of poly(lactide) - poly(butylene adipate-co-terephthalate) (PLA-PBAT) incorporated with ferulic acid was formed by solvent casting method. The influences of FA on the structural, colour, optical, thermostability, and antibacterial efficiency of PLA-PBAT blend films were studied. On the incorporation of the FA, thickness of the film was increased by 1.5–10 %. The tensile strength (TS) of the FA incorporated blend film increased to a value of 10.78 MPa at 10 wt% as compared to the control film which has 5.42 MPa. The temperature of degradation of the film increases as the FA content increases in the film. Antibacterial activity has been observed to increase due to the inclusion of the phenolic compound in the composite film against Listeria monocytogenes and Escherichia coli. The composite film has a potential application as an active food packaging due to its antibacterial and UV-light barrier properties.

用于食品包装的基于聚（丙交酯）/聚（己二酸丁二醇酯-共对苯二甲酸酯）混合物的阿魏酸活性薄膜

摘要 采用溶剂浇铸法制备了掺有阿魏酸的聚（丙交酯）-聚（己二酸丁二醇酯-对苯二甲酸丁二醇酯）（PLA-PBAT）的活性天然抗菌混合物。研究了 FA 对 PLA-PBAT 共混薄膜的结构、颜色、光学、热稳定性和抗菌效率的影响。加入 FA 后，薄膜的厚度增加了 1.5-10%。与具有 5.42 MPa 的对照薄膜相比，掺有 FA 的共混薄膜的拉伸强度 (TS) 在 10 wt% 时增加到 10.78 MPa 的值。薄膜的降解温度随​​着薄膜中 FA 含量的增加而增加。由于复合膜中包含酚类化合物，因此可以观察到抗菌活性增加，以对抗单核细胞增生李斯特菌和大肠杆菌。
