Natural Biocide Loaded PLA Films for a Possible Packaging Application
Making film with PLA appears to be very difficult process, as the PLA films formed are either very brittle, or very flexible. Hence, suitable solvent, time and temperature are to be optimised for the PLA film formation using trial and error method. However, many solvents dissolve PLA, and hence it can be solvent casted to make thin films that can be tested further. In the present work, PLA films were formed using chloroform as solvents with 1%, 5% and 10% natural biocide loading. The obtained films were analyzed by FTIR and TGA. Their mechanical and chemical properties were studied by tensile, hardness, water absorption and chemical resistance tests. Their anti-microbial activity against bacteria and fungi were also tested and the results are reported accordingly to reveal the feasibility of such natural biocide loaded PLA films for a possible packaging application.
