To extend food shelf life and reduce plastic pollution, halloysite nanotubes (HNTs) were employed as a carrier to load cinnamon essential oils (CEOs), and the nanotubes were blended with polybutylene adipate co-terephthalate (PBAT) resin to fabricate the film with non-contact antimicrobial activity. The results showed that the HNTs had a high loading efficiency (about 11%) for CEOs. The retention rate of CEOs in HNTs was still 33% after twenty days later, which indicated that the CEOs/HNTs nanoparticles had a long-acting controlled-released effect. The composite films represented excellent mechanical properties and antibacterial effects against and due to the non-contact antimicrobial activity of CEOs. The strawberries remained fresh after five days when the composite film was applied in the packaging of strawberries, which proves that composite films can extend the shelf life of food. Therefore, it has potential application prospects in the food industry.
为延长食品保质期并减少塑料污染，采用埃洛石纳米管（HNTs）作为载体负载肉桂精油（CEOs），并将纳米管与聚己二酸对苯二甲酸丁二醇酯（PBAT）树脂共混以制备具有非接触抗菌活性的薄膜。结果表明，HNTs对CEOs具有较高的负载效率（约11%）。二十天后，CEOs在HNTs中的保留率仍为33%，这表明CEOs/HNTs纳米颗粒具有长效控释作用。由于CEOs的非接触抗菌活性，复合薄膜表现出优异的力学性能和对[具体菌种1]和[具体菌种2]的抗菌效果。当复合薄膜应用于草莓包装时，草莓在五天后仍保持新鲜，这证明复合薄膜可以延长食品的保质期。因此，其在食品工业中具有潜在的应用前景。
