Overview of Natural Fiber-Based Packaging Materials

Abstract

One of the key elements of sustainability of humankind is the usage ratio of nature-based materials as opposed to synthetic products. This is very significant in the field of packaging materials, as people use and consume increasing amount of packaging materials every day. Packaging materials are usually produced from petroleum-based sources using non-degradable materials however, this has a negative impact on sustainability and the environment. It is important to replace them with natural-based materials, therefore cellulose is receiving more and more attention as a raw. Much research has been done for developing new nature-based packaging materials and technologies for replacement of synthetic materials. Recent articles review much research for developing methodologies, materials and composite materials for reducing environmental pollution. This paper reviews how natural-based packaging materials have spread and how it is used in many areas thanks to their favorable environmental effects. It summarizes the raw materials, additives and coatings of natural-based packaging materials, and it also addresses end-of-life options. The paper concerns also the most sensitive area of packaging is food packaging. Smart packaging is relevant for food packaging, and it seems to be one of the promising research areas for substituting artificial materials and providing additional functions.
