The effect of branching agent on the processability and mechanical properties of polylactic acid/
natural rubber blown film

Polylactic Acid (PLA) is currently known to be the cheapest and the most prevalent commercial bio-plastic. However, its
poor toughness and processability limited its applications in film blowing products. In this study, improvement in the
toughness of PLA was investigated by blending with Natural Rubber (NR) with the aid of a plasticizer. The improvement in
the bubble stability during film blowing process was investigated by using a peroxide Branching Agent (BA). The compound of
PLA, NR and a branching agent (PLA/NR/BA) was prepared by reactive melt blending method. The parameters investigated
are the PLA to NR ratio, the content of branching agent on the mechanical properties, processability and morphology of the
blend. The results indicated that NR could increase the tensile toughness and elongation at break of PLA blown films and the
use of higher amount of branching agent could allow stable processing of PLA/NR blends at higher NR content. The reactions
of branching agent with PLA and NR were verified by Fourier-transform infrared spectroscopy.
