4. Conclusion
The investigations revealed that PLA polymers could be synthesized by Lecitase Ultra and Lipozyme
TL IM catalysed polymerization from the commercial lactic acid. However, the PLA products derived
from lipase-catalyzed polymerization could not likely form the PLA films due to the lower molecular
weight of the PLA polymer than PLA products from chemical-catalyzed polymerization.
In any cases, this is not the prefix to develop a new material. Interestingly, this was that the PLA from
using lipase-catalyzed polymerization found possible under its mild condition. Consecutively, this
environmental friendly PLA could be blended with the commercial PLA (pure PLA). This gives
a promising alternative route for creating a new material. PLA of different blend ratios between the PLA
blend films produced from lipase-catalyst and the commercial PLA film showed more flexible and
degradable behavior greater than the only commercial PLA (pure PLA). An increasing of PLA blend
ratios increased the ability of PLA degradation in soil due to more water intake within the structures.
Indefinitely, an optimization of the PLA blending ratio will be needed to improve the quality of PLA
polymer for readily exploitation in the material industry. Nevertheless, the optimal conditions for PLA
degradability will support an explanation for its high capability and short time of the degradation
behavior in soil. Finally, this finding is quite potential as valuable tool for the production of bioplastics
to drive forward recently our new green biomaterials
