Lactic acid has been used in pharmaceutical, cosmetic, chemical and food industries. It can be used as a raw material in biodegradable plastics, such as polylactic acid (PLA) as well as to improve the physical properties ...

Lactic acid is an organic acid that has been extensively used worldwide in a variety of industrial and biotechnological applications. Lactic acid can be obtained chemically or by microbial fermentation. Production by ...

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 ...

Polymer membranes have been widely used in guided bone regeneration (GBR), especially when it comes to their use in dentistry. Poly (lactic acid) (PLA) have good mechanical properties such as flexibility, which allows the ...

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 ...

The preparation and characterization of biodegradable bilayer films from isolated soy protein (SPI) and poly (lactic acid) (PLA) were carried out in this work. The films showed high transparency and strong adhesion between ...

The aim of the present work is the evaluation of the aging behaviour of plasticized poly(lactic acid) (PLA) films depending on their plasticizer concentration. The main effect of plasticizer addition was a decrease on the ...

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 ...
