Poly(lactic acid) (PLA) can be synthesized from renewable bio-derived monomers and, as such, it is an alternative to conventional petroleum-based polymers. Since PLA is a relatively new polymer, much effort has been directed toward its development in order to make it an acceptable and effective option to the more traditional petroleumbased polymers. Commercially, PLA has received considerable attention in food packaging applications with a focus on films and coatings that are suitable for short shelf life and ready-to-eat food products. The potential for PLA to be used in active packaging has also been recognized by a number of researchers. This review focuses on the use of PLA in antimicrobial systems for food packaging applications and explores the engineering characteristics and antimicrobial activity of PLA films incorporated and/or coated with antimicrobial agents.

Poly (lactic acid) (PLA) is a non-toxic, compostable bio based material derived from starch and/or sugar and has high mechanical strength and plasticity. It is accepted as GRAS (Generally Recognized as Safe) by the Food and Drug Administration (FDA) and suitable for using in food and beverage packaging. PLA is primarily obtained from lactic acid which can be produced from renewable substances such as potato, wheat and corn starch. Petroleum based polymers cause an increase in fuel energy utilization and greenhouse gas emissions, however PLA is environmental friendly. Various polymers (protein, polycaprolactone (PCL) and polyhydroxy butrate (PHB)), fillers (wood, flax, and ramie) and additives have been combining with PLA in order to develop the performance of film and reduce the cost. On the other hand, PLA plays an important role in nanotechnology applications. Nan fillers like clay, montmorillonite and silica can be used for fortifying PLA composites. As a packaging material, PLA has a potential for manufacturing flexible films, extruded packages, containers of yoghurt, bottled water and juices, cups and lunch boxes. Moreover, in antimicrobial packaging, PLA is an excellent material which is able to be successfully incorporated with plant extracts (e.g. lemon), essential oils (e.g. oregano oil), enzymes (e.g. lysozyme) and metals (e.g. silver) in order to develop antimicrobial characteristics. In this mini review, the significance of PLA based packaging systems in food applications is discussed.

“…In recent years, with the continuous improvement of people s living standards and the upgrading of consumer market, food safety issues are increasingly becoming the focus of attention, so under this circumstance, nano-packaging materials have gradually come into people s vision. By adding nanoparticles into packaging materials, nano-packaging materials are modified and compounded, thus giving new materials antibacterial properties, mechanical properties and air permeability [7][8][9]. Nano-TiO 2 is the most important one among many nano-materials.…”

To study the relationship between performance changes and nanoparticles migration of the composite film at different migration stages, the poly (lactic acid) (PLA)/nano-TiO2 composite film treated by high pressure was immersed in 50% (v/v) ethanol solution for 45 days at 40 °C, and the film characteristics and migration behavior were analyzed. The results showed that the migration of the composite film with the highest loading of nano-TiO2 (20 wt. %) in alcoholic food simulated solution was far less than 10 mg/kg during the 45-day migration process. Although with the increase of migration time, the micro-morphology of composite film became rougher, the crystallinity decreased and the gas permeability increased, but the internal crystal structure of the composite film remained basically unchanged. The PLA/nano-TiO2 composite films treated by high pressure treatment were relatively stable, and had good performance and migration behavior in alcoholic food simulated solution, the nanocomposite film after high pressure treatment could be used to reduce nano-TiO2 particle migration and subsequently reduce human exposure as the packaging film for the packaging of alcoholic food, which provide a theoretical basis for the applications of high pressure treatment of PLA/nano-TiO2 composite films in food packaging material and broaden its application prospects.
