| Summary: | There is abundance of waste from the usage of petroleum based plastic thus causing the environmental pollution in the world. Most of the plastic are non-recyclable and non-degradable. Hence, this work was directed towards developing biodegradable films from natural resources that are more sustainable and environmentally friendly compared with the petroleum derived plastic. Tapioca starch was used as the matrix of the biodegradable film due to economical and exhibits good transparency than to other starch. However, the usage of tapioca starch has been limited due to the poor mechanical, barrier and thermal properties. Microcrystalline cellulose (MCC) at different concentration was incorporated as the filler into the biopolymer films to form composite in order to improve these limited properties. Solvent casting method was used to produce the film due to easy fabrication and low processing cost. It was found that, the tapioca starch films incorporated with 3% (w/w) MCC are exhibited the highest tensile strength and Young’s modulus but the lowest elongation at break due to strong interaction between the MCC and starch matrix. However, the films became slightly semitransparent when MCC concentration was increased. Barrier properties of the films were also improved by the addition of MCC on the starch film due to the formation of tortuous path created by MCC. The thermal properties of the films also exhibit improvement with the addition of MCC into the tapioca starch. As a conclusion, it was found that the tapioca starch /MCC films produced in this study exhibit improved properties and have the potential to be used as food packaging film. |
