| Summary: | The signifcant value of renewable resources used for food packaging has motivated consumer demand, thereby driving
consumers to pay closer attention to biodegradable packaging applications. Polylactic acid (PLA) together with durian skin
fbre (DSF), epoxidized palm oil (EPO) and cinnamon essential oil (CEO) have been used to produce thin flm via the solution
casting method. This research study was conducted to optimise the potential efect of DSF content, EPO content and CEO
content by determining the tensile properties of PLA biocomposites. The design of experiments (DOE) via response surface
methodology was used to analyse the results. The optimum values for the tensile properties of PLA biocomposite were found
at 3 wt% DSF, 5 wt% EPO and 1 wt% of CEO. The optimum tensile strength and tensile modulus of PLA composite were
24.9 and 375.9 MPa, respectively. The DSF content infuences the tensile properties of PLA biocomposite, followed by the
EPO content and CEO content based on the analysis of variance. The P value of both responses in the design of experiments
is less than 0.05 which verifes that the tensile properties model is signifcant. The coefcient, R2
, for tensile strength is
0.8908, while the coefcient result of the tensile modulus is 0.8916. |
