Abstract
In this study, the innovative polymer composite materials based on poly(lactic acid) (PLA) and rice hulls have been investigated for their application for food packaging. The compression and injection molding of PLA based composites reinforced with rice hulls have been carried out and their basic properties were examined. Rice hulls from rice processing plants represent renewable sources that could be utilized as a filler for polymer composites. Maleic anhydride grafted PLA (MAPLA) was used as coupling agents (CA) to improve the compatibility and adhesion between filler and matrix. The composites containing 30 wt % reinforcement was manufactured by compression and injection molding and their mechanical and thermal properties were investigated. The flexural strength of the compressed composite sample is 51. 3 MPa in comparison with 46.7 MPa for the same composite produced by injection molding technique. The experimental results suggest that the compression and injection molding are promising techniques for processing of PLA- based composites. The polymer composites based on PLA and rice hulls are suitable for applications as innovative material for food packaging.
