| Summary: | The emergence of many new food products on the market has led to food spoiling during its shelf life and many food packages being thrown away. Therefore, nano bio-plastic packaging has been introduced in the packaging industry. Nano bio-plastic packaging helps to prolong the shelf-life of products through the use of nanoparticles and essential oil. In addition, nano bio-plastic packaging was made from biodegradable polymers that can be decomposed. Nano bio-plastic films made from polylactic acid (PLA) and nanoclay were produced using a solvent casting method with addition of 1.0%, 3.0% and 5.0% (wt.) nanoclay and a constant volume of lemongrass essential oil were added to the PLA solution. The mechanical, physical, chemical, and antimicrobial properties of the nano bio-plastic films were investigated. To analyses the film samples, tensile testing, FTIR analysis, UV-barrier testing, and scanning electron microscopy (SEM) were performed. The feasibility study on the using of nano bio-plastic as fruit packaging was done on red grapes for 14 days. |
