Processing Polymer Blends of Mater-Bi^® and Poly-L-(Lactic Acid) for Blown Film Application with Enhanced Mechanical Strength.

ABSTRACT: Mater-Bi^® is one of the most commercialized starch-based blends used in biodegradable flexible packaging. However, the high ductility and low stiffness of Mater-Bi^® might limit its application and developing a solution to tailor the stiffness and mechanical strength is highly desirable. In the present work, blends based on Mater-Bi^® and poly-L-(lactic acid) (PLLA) at a different ratio from 70/30 to 50/50 wt% were prepared via melt-extrusion and the effect of the PLLA content and Joncryl ADR^® as a reactive compatibilizing agent, on the mechanical properties, melts rheology, morphology and disintegration aptitude were investigated. The inclusion of PLLA in Mater-Bi^® has a marked beneficial effect on the tensile strength and stiffness of
