Biodegradable Polymer Research for Packaging Applications

Poly(lactic acid) is one of the biodegradable polymers, which is getting the attention of many researchers. Because of environmental friendliness, renewable materials and suitable for packaging to substitute polymers made from petroleum. However, poly(lactic acid) limitations are brittleness, low impact strength and low elongation at break restrict the applications. For packaging application, In addition to the need for environmental friendly materials, antibacterial packaging that can against bacteria is also desirable. For the safety of consumer’s health from bacterium, which causes diarrhea and foodborne illness. The incorporation of anti-bacterial agents in biodegradable polymer is required.

The working scope in the P-PROF research group are focusing on improvements of mechanical properties of poly(lactic acid), including property modifiers, anti-bacterial performance of anti-bacterial agent in poly(lactic acid) matrix, effect of processing conditions and degradation mechanism (pre-treatment, abiotic and biotic-degradation) of poly(lactic acid).
