Quaternary Ammonium Chitosan Derivative Embedded PBAT/PLA Films: As a Biodegradable Food Packaging Materials with Antibacterial Properties |
| 초록 |
Common types of polymers used in food packaging materials (e.g., PE, PP, PET etc.) cause serious environmental issues due to nonrenewable nature of polymers and their inability to be biodegradable. In this study, we developed poly(butylene adipate-co-terephthalate)/poly(lactic acid) (PBAT/PLA) films embedded quaternary ammonium chitosan (QAC) derivative with antibacterial properties. PBAT as flexible compostable polymer was blended to PLA to improve flexibility and biodegradability. PBAT/PLA film display their antimicrobial activity by release of QAC from the PBAT/PLA matrix or exposure to the PBAT/PLA matrix surface. As a result, antibacterial efficiency against Staphylococcus epidermidis and Escherichia coli were determined. Fabrication of biodegradable films with antibacterial properties can be applied to the various food packaging materials in food industry to improve environmental Impacts and hygiene. |
