Resumen:
The aim of this work was to prepare polylactic acid / poly(3-hydroxybutyrate) (PLA/PHB) blends plasticized with tributyrin (TB) for food packaging applications, as a sustainable alternative to current non-natural and non-biodegradable materials. In particular, we focus the investigation on the biodegradability of materials. The disintegrability under composting conditions revealed that while PLA and TB facilitated the hydrolysis process, PHB delays the disintegration of PLA matrix. The rate of disintegration was longer for PLA/PHB blends with respect to PLA counterparts due to the increased crystalline phase and the surface water resistant. However, all formulations resulted fully disintegrated under composting in times compatible with the regular composting time.
