The biodegradation and disintegration of thermoplastic starch multilayers containing carvacrol(CA)-loaded poly-(ε-caprolactone) electrospun mats were evaluated under thermophilic composting conditions for 45 and 84 days, respectively, and compared with non-loaded carvacrol films and pure starch films. Sample mass loss, thermogravimetric and visual analyses were performed throughout the disintegration test. The disintegration behaviour of all multilayers was similar, reaching values of 75–80% after 84 days. Biodegradation, assessed by carbon dioxide measurements, revealed that all the carvacrol-free films completely biodegraded after 25 composting days. However, the presence of CA notably affected the compost inoculum activity, thus limiting the biodegradability of the CA-loaded multilayers to a maximum value of around 85% after 45 days. Nevertheless, this value was close to that established by the standard ISO method to qualify as biodegradable material.

在嗜热堆肥条件下分别评估了含有香芹酚（CA）负载的聚（ε-己内酯）电纺垫的热塑性淀粉多层膜的生物降解和崩解，并将其与未负载的香芹酚薄膜和纯淀粉薄膜进行了比较。在整个崩解测试中进行样品质量损失，热重和目测分析。所有多层的崩解行为相似，84天后达到75-80％的值。通过二氧化碳测量评估的生物降解表明，在堆肥25天后，所有无香芹酚的薄膜都完全被生物降解。但是，CA的存在显着影响了堆肥接种物的活性，因此将装载CA的多层膜的生物降解能力限制在45天后的最大值约为85％。
