Biodegradable polymers from renewable resources are sought after for many purposes, from packaging materials in food to biomedical applications. Poly lactic acid PLA is a well-known biopolymer derived from corn starch or sugar cane used in different food packaging and artificial bones and scaffolds. Poly lactic acid Science and Technology first introduces the basic concepts of PLA and then covers PLA synthesis and polymerization, processing, characterization and physical properties of PLA, PLA-based nano-biocomposites, the main applications in active packaging and as biomaterials for tissue engineering, degradation and biodegradation of PLA and finally industrial and legislative issues. Experts provide a complete resource and whole perspective on PLA covering scientific, ecological, social and economic issues. The book will appeal to chemists, food technologists and materials engineers as well as researchers interested in bio-based and biodegradable polymers and composites.

The number of research papers on the electrical properties of bioplastics [ 1 — 5 ] is relatively small. Polylactic acid PLA is a kind of bioplastic plant derived material made of cornstarch and other vegetable products. This is a carbon-neutral material: when buried in the ground for disposal, it is decomposed into hydrogen and carbon dioxide by microorganisms, and these products are then reused for plant photosynthesis. These features have brought PLA increased attention recently as a resource-circulation material. As PLA is a hard resin, it has to be softened before it can be used as electrical wire sheathing.
Polylactic Acid PLA is the first viable thermoplastic that can be produced from a plant-based feedstock such as corn or sugar cane, and yet be processed by the conventional melt processing technologies. At the same time, Polylactic Acid is produced at the largest industrial scale of all biodegradable polymers. It is being used in biomedical applications, for bottle production and in compostable food packaging. It is also being evaluated as a material for tissue engineering. Mass production has tremendously reduced the cost of PLA production, making it an economically viable choice for fabrication of domestic containers, plastic bags, and fibers. Commercial-scale plants today produce hundreds of thousand tons of PLA per year. This book provides a practical guide for the engineers and scientists involved in working with PLA and developing the many new products that are emerging for this important biopolymer.
