Abstract

In this study, we prepared bioplastic from the red alga Gracilaria verrucosa agar. Characteristics of this bioplastic derived agar are evaluated under a set of experiments. We discussed the potential role of agar and glycerol concentration on improving the bioplastic texture, elasticity and strength. We reported here that the obtained bioplastic is transparent, odorless, resistant to heat above 100 °C and had low water permeability at 25 °C. It also preserved its intact texture and proprieties during at least 9 months at room temperature.
