Title |
Degradation Study of Biodegradable Plastic using Nata De Coco as a Filler. |
Producing novel sago starch-based food packaging films by incorporating lignin isolated from oil palm black liquor waste.
|
Synthesis and Characterization of Cross-linked Starch/Lignin film. |
Uses of sunflower seed fried oil as an eco-friendly plasticizer for starch and application of this thermoplastic starch as filler for PLA. |
|
FTIR |
Samples in the form of plastic were placed in set holder and scanned at a wavelength of4000-400 cm -1 |
No usage of FTIR |
Recorded on an Avatar 360 spectrophotometer at wavelength 4000-400 cm -1 with a resolution 4 cm -1 |
No usage of FTIR |
|
Tensile Test |
Universal Testing Machine (UTM) ASTM method D.882-02 |
Using standard method (ASTM,1980) with 5 kg loads with distance between the grips set at 50 mm and cross head speed at 0.40 mm/s |
Films were cut 100 mm x 10 mm and determined with Tensile Tester Instron XLDT 1kN (China) with an extension speed of 5 mm/min |
10 mm x 5 mm x 200 µm were subjected to Perkin Elmer DMA 8000 with maximum load to 2N and a load rate of 0.1 N/min |
|
Water Vapor Permeability |
Using the gravimetric method (ASTM 1983) where the plastic was placed in the mouth of cup with silica gel |
Measured by using ASTM E96-95 method with slight modifications |
No water vapor permeability testing |
No water vapor permeability testing |
|
Water Solubility Test |
No water solubility test |
Films were cut 2 x 3 cm and placed in a desiccator containing silica gel for 7 days |
No water solubility test |
No water solubility test |
|
Biodegradation Test |
Burying the sample 3 x 3 cm 2 in the soil for 12 days with every two days plastic was taken, washed and weighed |
