Özet:
Waste management becomes more important day by day because of increasing population of the world. Many methods have been considered as sustainability solutions. One of the popular methods for enhancing the sustainability is the disposal of the waste by biodegradable alternatives. PLA granule is the most common granule in packaging industry which is produced from biobased and biodegradable ingredients. In this study, biobased and biodegradable film production was evaluated. The PLA film is hard to form and more brittle than many films which are produced from petroleum based granules. This causes inefficiency in the food packaging and printing machine. Rigidity of PLA was reduced by using different raw materials used in shopping bags film. The shopping bags produced from Mater-Bi granules are more ductile than petroleum-based standard packaging materials. Mater-Bi granule is biobased and biodegradable like PLA granule. Both PLA and Mater-Bi granules were solved as 100% PLA, 80%PLA-20% Mater-Bi, 70%PLA-30%Mater-Bi, 60%PLA-40% Mater-Bi and 100% Mater-Bi films. Properties are changed with the difference of Mater-Bi percentage. Thickness, unit weight, efficiency, tensile strength and puncture resistance were tested for determining the mechanical properties. Another important criteria for food packaging is sealing performance, which is tested in order to ensure food safety. Marketing concerns are also important; so optical properties of the produced packaging films were tested. Films were produced between the yellowish appearance of Mater-Bi and the transparent appearance of PLA. FTIR analyzes were also conducted for analytical characterization Gas Chromatography test was performed in order to check that it is suitable for regulations in terms of food safety. The formulations were evaluated according to the test results.
