ABSTRACT: The high brittleness of Poly(lactic acid) is a major drawback for flexible food packaging applications. The aim of this work is to evaluate the potential use of commercial adipates as PLA plasticizers to obtain ...

BACKGROUND: Amorphous poly(lactic acid) (PLA) was plasticized with two polyadipates with different molar masses. Some physical properties were studied over time to evaluate the stability of these blends. The aim of this ...

Poly(lactic acid)/bacterial cellulose nanocomposites were prepared by solvent casting. Aiming to reduce the incompatibilitybetween polar bacterial cellulose (BC) and the nonpolar PLA matrix which induces iller aggregation ...

Biodegradable films based on poly(lactic acid) blends were obtained by cast extrusion. Their tensile and fracture behaviorwas investigated and the effect of the processing conditions through the extrusion rolling speed on ...

Iron is an essential micronutrient for higher plants. Although abundant in most soils, Fe3+ is not available for plant uptake, because of its poor solubility. Ferrous sulfate is a fertilizer used for crops but, Fe2+ is ...

The aim of this work is focused on the direct 3D-printing of poly(lactic acid) (PLA) on a cotton textile substrate, and the study of the printing parameters that modify their adhesion. PLA samples are printed by using Fused ...

Nowadays, scientific and technological efforts are being carried out to diminish serious ecological problems caused by indiscriminate use of non-biocompostable polymers in the packaging industry. In this sense, novel ...

In the present work, solid-state drawing of commercial PLA-based extruded filamentswas investigated. Two different filaments were used: one based on neat PLA and theother based on PLA filled with copper particles. The ...
