Composites Materials for Food Packaging

Introduction

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.

Materials and Structures

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.

Biodegradable and Synthetic Materials

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.
