Abstract:

In many industries, the interest in biodegradable packaging with antimicrobial properties has increased strikingly. Today, food packaging materials have been highly articulated in terms of the effects on the ecological system and the importance of biodegradable materials. Natural fibres and fillers are an inexhaustible source of biobased materials: wood flour is already used in mass production of wood plastic composites while cellulosic fibres from other plants (flax, sisal, jute) for the reinforcement of thermoplastic and thermoset polymers. Petrochemical industries accounts for millions of tons of CO2 emissions every year. However, antimicrobial packaging systems have gained importance in the recent years of studies to prevent microbial growth on the food surface, to control it and to prevent food quality loss. Biodegradable polymers such as polylactic acid (PLA), cellulose esters, polyhydroxyalkanoates (PHA) and starch polymers can be reinforced with natural-based fillers to produce eco-friendly composites. In this study, natural and antibacterial PLA film have been produced by using olive leaf extract. PLA film are biodegradable and environmental friendly. Antimicrobial efficacy of the obtained products on Bacillus cereus (B. cereus) and Escherichia coli (E. coli) was investigated. It is suitable for safe food packaging. In addition, the PLA/Olive Leaf Extract composite films was examined optical and thermal properties and was comparison with pure PLA film.
