Starch/polyester blends are potential substitutes for non‐degradable materials. Active food packaging was produced by the blown‐extrusion of starch/poly (butylene adipate‐co‐terephthalate) (PBAT) blends added to α‐tocopherol (α‐TOC). The films showed adequate stability and processability by the blown‐extrusion method and were converted into an essentially amorphous and homogeneous material. The transparency and water vapor permeability of the films increased with the addition of α‐TOC. The antioxidant interfered in the organization of the polymeric matrix, which was confirmed by SEM images, resulting in lower tensile strength and elongation at break, with no interference due to the α‐TOC concentration. The inclusion of α‐TOC did not influence the thermal stability, and it increased the crystallinity of the samples. The formulation with the lowest concentrations of the antioxidant (T0.25) presented an almost complete release of α‐TOC, proving the efficiency of the films as active packaging. The complete degradation of the materials was proved by evaluating the composting of the films. The eco‐friendly films are promising materials for active food packaging.

吹膜挤出生产的环保材料可作为潜在的活性食品包装

淀粉/聚酯共混物是不可降解材料的潜在替代品。活性食品包装用淀粉/聚（亚丁基己二酸酯的吹塑挤出制备共对苯二甲酸酯（PBAT）混合物已添加到α-生育酚（α-TOC）中。薄膜通过吹塑法表现出足够的稳定性和可加工性，并被转化为基本上无定形和均质的材料。添加α-TOC可以提高薄膜的透明度和透湿性。抗氧化剂会干扰聚合物基体的组织，这已通过SEM图像得到证实，从而导致较低的拉伸强度和断裂伸长率，而不会受到α-TOC浓度的干扰。包含α-TOC不会影响热稳定性，并且会增加样品的结晶度。最低抗氧化剂浓度（T0.25）的制剂几乎完全释放了α-TOC，证明了薄膜作为活性包装的效率。通过评估薄膜的堆肥，证明了材料的完全降解。环保薄膜是用于活性食品包装的有前途的材料。
