Abstract

Edible film is a thin and transparent plastic made from edible materials and protects material from damage due to the environment and microorganisms disaster. Polylactic acid (PLA) is one of polymer which potentially used as raw material of edible films. PLA is a very fragile nature material, so it necessary combining PLA with nanocrystaline cellulose (CNC) to improve it is properties. Combining PLA with nanocrystaline cellulose (CNC) could increase the mechanical properties of tensile strength and elongation at break of PLA. The aim of this study was to obtain the the best formulation of PLA-CNC to get the optimum tensile strength and elongation at break of PLA. The result showed that the addition of CNC was decrease tensile strength and increased elongation at break. The best mechanical properties of edible film is reached by using 20% CNC.
