The novel insights, as well as the main drawbacks of each engineered composites material is extensively evaluated taking into account the strong relationship between packaging materials, environmental and reusability concerns, food quality, and nutritional value. Composites, by matching the properties of different components, allow the development of innovative and performing strategies for intelligent food packaging, thus overcoming the limitations of using only a single material. The book starts with the description of montmorillonite and halloysite composites, subsequently moving to metal-based materials with special emphasis on silver, zinc, silicium and iron. After the discussion about how the biological influences of such materials can affect the performance of packaging, the investigation of superior properties of sp2 carbon nanostructures is reported. Here, carbon nanotubes and graphene are described as starting points for the preparation of highly engineered composites able to promote the enhancement of shelf-life by virtue of their mechanical and electrical features. Finally, in the effort to find innovative composites, the applicability of biodegradable materials from both natural (e.g. cellulose) and synthetic (e.g. polylactic acid - PLA) origins, with the aim to prove that polymer-based materials can overcome some key limitations such as environmental impact and waste disposal. Audience The book will interest researchers in academia and industry in food science/safety, pharmaceutical and biomedical fields, materials science, especially those specializing in composites and biomaterials, polymer science, plastics engineering and nanotechnology.

Polymers are an important part in everyday life; products made from polymers range from sophisticated articles, such as biomaterials, to aerospace materials. One of the reasons for the great popularity exhibited by polymers is their ease of processing. Polymer properties can be tailored to meet specific needs by varying the atomic composition of the repeat structure, by varying molecular weight and by the incorporation (via covalent and non-covalent interactions) of an enormous range of compounds to impart specific activities. In food science, the use of polymeric materials is widely explored, from both an engineering and a nutraceutical point of view. Regarding the engineering application, researchers have discovered the most suitable materials for intelligent packaging which preserves the food quality and prolongs the shelf-life of the products. Furthermore, in agriculture, specific functionalized polymers are used to increase the efficiency of treatments and reduce the environmental pollution. In the nutraceutical field, because consumers are increasingly conscious of the relationship between diet and health, the consumption of high quality foods has been growing continuously. Different compounds (e.g. high quality proteins, lipids and polysaccharides) are well known to contribute to the enhancement of human health by different mechanisms, reducing the risk of cardiovascular disease, coronary disease, and hypertension. This first volume, of this two volume book, concerns the application of polymers in food packaging.
