Nanoclay Packaging Materials as Biodegradable

Abstract

Nanoclays are nanomaterials consisting of layered silicate clay minerals and have various applications in food packaging. They can improve the mechanical, thermal, and barrier properties of both petroleum-based and bio-based polymers, as well as provide other functions such as antimicrobial activity, colorimetric indication, biodegradability enhancement, additive partitioning, and control and release of active ingredients. This chapter reviews the types, properties, and manufacturing methods of nanoclay-based polymer nanocomposites for food packaging. In addition, the latest achievements and challenges related to the use of nanoclays as food packaging materials are discussed, and an overview of the current state of knowledge and future perspectives for the development of nanoclay technology in the food industry is provided.
