A novel casting method for producing plasticised PLA films, intended for food packaging and biomedical applications, is presented in this current work. This method involves air-induced, temperature-controlled phase separation (AITCPS), which enables the formation of highly dense PLA matrices. A broad study is provided to understand the effects of glycerol used as a plasticizer on various physiochemical properties including morphological, thermal, mechanical, and interfacial properties, as well as water vapor transmission rates and antimicrobial activities. The results demonstrate how the plasticizer ratio has a minimal impact on the thermal properties of the films, although it simultaneously enhances the mechanical and interfacial properties of the material.

Abstract
A novel casting method for producing plasticised PLA films, intended for food packaging and biomedical applications, is presented in this current work. This method involves air-induced, temperature-controlled phase separation (AITCPS), which enables the formation of highly dense PLA matrices. A broad study is provided to understand the effects of glycerol used as a plasticizer on various physiochemical properties including morphological, thermal, mechanical, and interfacial properties, as well as water vapor transmission rates and antimicrobial activities. The results demonstrate how the plasticizer ratio has a minimal impact on the thermal properties of the films, although it simultaneously enhances the mechanical and interfacial properties of the material.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
