Food packaging, often underestimated, plays a crucial role in the supply chain and our daily lives. During storage, distribution, and marketing, packaging must contain and protect food, communicate its characteristics, and present convenience to the consumer. Various packaging materials, mainly synthetic polymers derived from petroleum, are available. However, the growing concern about pollution and the environmental impact generated by this type of material drives us to rethink our choices, and the search for solutions has become more urgent than ever. This new book, Sustainable Food Packaging Materials and Technology, addresses one of the most pressing challenges of our era: how to preserve the quality, safety, and, in some cases, freshness of food with packaging based on sustainable materials that do not compromise the environment.
Each chapter provides a technical analysis of materials and their application and presents a comprehensive overview of using available resources responsibly and creatively. Some chapters reveal the transformative potential of waste resources, from using by-products from the fishing industry to materials derived from agaves. The volume also explores the use of natural polymers such as proteins and polysaccharides in the design of packaging and coatings, highlighting their capacity to offer biodegradable solutions that can also be highly effective. Within polysaccharides, the book looks into the great potential offered by starch and cellulose, which, thanks to their versatility and properties, have become some of the most explored renewable materials in creating biodegradable packaging and coatings.
An innovative aspect of this book is its emphasis on active biodegradable packaging and coatings, which integrate antioxidant and antimicrobial properties by utilizing agro-industrial waste. This convergence of sustainability and functionality offers an effective solution to combat food waste, a global challenge requiring immediate attention. The revolutionary materials polybutylene succinate (a biodegradable biopolymer) and polyethylene furanoate (a recyclable material) have also been explored, which redefine expectations about packaging sustainability. These advances promote the circular economy and offer a roadmap to a greener future.
We hope this book serves as a guide and a rich source of inspiration in the search for more sustainable and responsible food packaging. Sustainable Food Packaging Materials and Technology will be valuable for researchers and scientists in the food packaging industry.
