Biodegradable polymers are a suitable alternative for replacing traditional food packaging with environmental concerns. Poly(butylene adipate-co-terephthalate) (PBAT) is a synthetic biodegradable polymer with high flexibility and a high potential for functionalization, aiming at bactericidal, antimicrobial, or antifungal properties. In this work, the casting method was used to prepare PBAT films containing Moringa oleifera (MO) seed powder. The MO was added in different contents of 0, 1, 3, 5, and 10% (wt) to functionalize the film properties and its efficiency as strawberry packaging. The PBAT films containing 1% (wt) of MO were the most suitable for packaging applications, considering the mechanical properties and thermal properties. MO did not present significant interactions with the PBAT matrix and reduced the PBAT crystallinity, leading to a decrease in gas and water vapor permeabilities. The PBAT-1% MO films showed good performance as biodegradable packaging for strawberry storage, prolonging their storage time and reducing their vulnerability to fungal attack. Besides, the MO decreased the fungal contamination of strawberries when compared to those stored in neat PBAT. The developed films performance suggests that the PBAT/MO films have good potential to be used as active food packaging.

可生物降解的聚合物是替代具有环境问题的传统食品包装的合适选择。聚（亚丁基己二酸酯共-terephthalate）（PBAT）是具有高的灵活性和用于官能化具有高电势的合成生物可降解聚合物，旨在杀菌，抗微生物剂，或抗真菌性质。在这项工作中，采用流延法制备含辣木的PBAT膜（MO）种子粉。以0、1、3、5和10％（wt）的不同含量添加MO，以功能化薄膜性能及其作为草莓包装的效率。考虑到机械性能和热性能，含有1％（wt）的MO的PBAT膜最适合包装应用。MO没有与PBAT基质发生明显的相互作用，并降低了PBAT的结晶度，导致气体和水蒸气的渗透率降低。PBAT-1％MO膜作为可生物降解的草莓贮藏包装显示出良好的性能，延长了贮藏时间并降低了其对真菌侵袭的脆弱性。此外，与纯PBAT中储存的MO相比，MO减少了草莓的真菌污染。
