The purpose of this study is to develop polymer composite masterbatches by using poly(lactic) acid as a carrier resin and bamboo charcoal particle as a natural pigment. Moreover, antioxidant and dispersing agent were added to the masterbatches where the antioxidant improves thermal and ultraviolent stability of pigment masterbatches while dispersing agent enhances the distribution and dispersion of bamboo charcoal particles in the polymer matrix. The natural pigment masterbatches were diluted in the poly(lactic) acid matrix. The morphology, thermal property, and rheological properties of bamboo charcoal particles/poly(lactic) acid composites comparing before and after weathering tests are studied. It was concluded that natural pigment charcoal masterbatches can make good bamboo charcoal particles/poly(lactic) acid composites for high‐temperature food packaging applications.
