“…The hydrophilicity of chitosan also provide good grease barrier [63]. In paper coating, chitosan is usually blended with other biopolymers or nanomaterials to improve mechanical and barrier properties of coated paper [64]. Moreover, the positively charged chitosan results in a good affinity and a good retention or adhesion on paper fiber surface [63].…”

As one of the most abundant natural polymers in nature, polysaccharides have the potential to replace petroleum-based polymers that are difficult to degrade in paper coatings. Polysaccharide molecules have a large number of hydroxyl groups that can bind strongly with paper fibers through hydrogen bonds. Chemical modification can also effectively improve the mechanical, barrier, and hydrophobic properties of polysaccharide-based coating layers and thus can further improve the related properties of coated paper. Polysaccharides can also give paper additional functional properties by dispersing and adhering functional fillers, e.g., conductive particles, catalytic particles or antimicrobial chemicals, onto paper surface. Based on these, this paper reviews the application of natural polysaccharides, such as cellulose, hemicellulose, starch, chitosan, and sodium alginate, and their derivatives in paper coatings. This paper analyzes the improvements and influences of chemical structures and properties of polysaccharides on the mechanical, barrier, and hydrophobic properties of coated paper. This paper also summarizes the researches where polysaccharides are used as the adhesives to adhere inorganic or functional fillers onto paper surface to endow paper with great surface properties or special functions such as conductivity, catalytic, antibiotic, and fluorescence.

“…Most often, alginates are crosslinked for improvement of their resistance in water, mechanical properties, and coherence [ 31 ]. Chitosan, extensively investigated especially in the medical sector, is a known natural bio-active polymer with an immanent antimicrobial activity, which promotes its usage as a film or coating, for preservation and storage of numerous foods, mainly fruits and vegetables [ 32 ]. This polysaccharide composed of randomly distributed β-(1–4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit) is derived mainly from chitin shells of crustaceans, but is also synthesized by some fungi belonging e.g., to Mucoraceae .…”

Similarly to other biopolymers, in order to improve chitosan mechanical properties, its performance in terms of water vapor permeability and water solubility the combinations with other biomolecules (pectin, starch, alginate, gelatin) are being investigated providing varied results [ 32 , 33 ].…”

Bacterial Nanocellulose—A Biobased Polymer for Active and Intelligent Food Packaging Applications: Recent Advances and Developments

The aim of this review is to provide an overview of recent findings related to bacterial cellulose application in bio-packaging industry. This constantly growing sector fulfils a major role by the maintenance of product safety and quality, protection against environmental impacts that affect the shelf life. Conventional petroleum-based plastic packaging are still rarely recyclable and have a number of harmful environmental effects. Herein, we discuss the most recent studies on potential good alternative to plastic packaging—bacterial nanocellulose (BNC), known as an ecological, safe, biodegradable, and chemically pure biopolymer. The limitations of this bio-based packaging material, including relatively poor mechanical properties or lack of antimicrobial and antioxidant activity, can be successfully overcome by its modification with a wide variety of bioactive and reinforcing compounds. BNC active and intelligent food packaging offer a new and innovative approach to extend the shelf life and maintain, improve, or monitor product quality and safety. Incorporation of different agents BNC matrices allows to obtain e.g., antioxidant-releasing films, moisture absorbers, antimicrobial membranes or pH, freshness and damage indicators, humidity, and other biosensors. However, further development and implementation of this kind of bio-packaging will highly depend on the final performance and cost-effectiveness for the industry and consumers.

Due to higher expectations for health in recent decades, the issues of food preservation and safety are now attracting more and more attention. Therefore, research and development of food packaging materials is of important practical significance. While the wide use of functional plastic packaging brings great convenience to the food industry, serious problems also appear subsequently, such as source exhaustion, plasticizer transfer, and other potential food safety hazards, which pose great challenges to researchers. In order to overcome these shortcomings, the natural polysaccharide chitosan has emerged as a suitable food packaging material. Chitosan has many excellent properties such as biodegradability, biocompatibility, bioactivity, nontoxicity, and polycationic nature. This article reviews the discovery and preparation process of chitin and chitosan. In addition, the application of chitosan‐based films in food storage is highlighted. Finally, the future perspectives of chitosan are proposed.
