Replacing petro-based materials in personal care sector with renewable biodegradable counterparts is a correct strategy for taking care of the environment. Textured films are currently used in several applications in contact with skin, such as diaper and napkins. Poly(lactic acid) (PLA), fully renewable and compostable, with an intrinsic anti-microbial property, has enormous potentialities but it is necessary processing it by flat die extrusion to obtain flexible films. The plasticization of selected polymeric blends, obtained by using biodegradable and partially biobased polyesters as well as a citrate, and the control of melt viscosity by proper additives during extrusion were thus investigated.

Abstract
Replacing petro-based materials in personal care sector with renewable biodegradable counterparts is a correct strategy for taking care of the environment. Textured films are currently used in several applications in contact with skin, such as diaper and napkins. Poly(lactic acid) (PLA), fully renewable and compostable, with an intrinsic anti-microbial property, has enormous potentialities but it is necessary processing it by flat die extrusion to obtain flexible films. The plasticization of selected polymeric blends, obtained by using biodegradable and partially biobased polyesters as well as a citrate, and the control of melt viscosity by proper additives during extrusion were thus investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
