PHB/PLA plasticized by olive oil and carvacrol solvent-cast films with optimised ductility and physical ageing stability

Demetres Briassoulis et al.

Summary: Polylactic acid (PLA) and polyhydroxybutyrate (PHB) are commonly used bio-based polymers for food packaging. However, PHB is brittle and suitable for rigid packaging, while flexible packaging can be achieved through blending or co-extrusion with other bio-based polymers and additives such as PLA. This study explored the potential of blends of PHB with other bio-based polymers and additives for food packaging film applications, and successfully developed optimized compositions of these blends.

Fabrication of highly efficient phenylphosphorylated chitosan bio-based flame retardants for flammable PLA biomaterial

Xiaobing Ma et al.

Summary: Modified chitosan-based flame retardants, such as phenylphosphorylated CS (PhPCS) and phenylphosphoramidated CS (PhPNCS), show promising prospects due to their sustainability, biodegradability, and good charring properties. These bio-based flame retardants exhibited excellent flame retardancy efficiency for poly(lactic acid) (PLA), but the mechanical properties of PhPCS-based biocomposites decreased with increasing content. On the other hand, PhPNCS-based biocomposites showed improved mechanical strengths due to the reactive compatibilization between the PhPNCS nanoparticles and PLA matrix.

Pengwu Xu et al.

Summary: This study aimed to improve the crystallization and mechanical properties of poly(hydroxyalkanoate)s (PHA) by using hydrazide compounds as nucleating agents.
