“…It is a linear polymer (molecular weight ranging from tens of thousands to hundreds of thousands [17]) formed by d-glucopyranose via β-1,4-glucosidic bonds ( Figure 2). Although cellulose has long molecular chain and high hydroxyl content, the solubility of cellulose in general solvent is limited [18]. The solubility of cellulose can be improved by chemical modification resulting in better applications in paper coating.…”

“…Starch is also a promising polysaccharide applied as barrier coatings. The main chain structure of starch consists of d -glucopyranose and is connected by α-1,4-glucoside bond [ 18 ], which determines its natural spiral structure. According to whether starch has branched chains, starch can be divided into amylose ( Figure 6 a) and amylopectin ( Figure 6 b).…”

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.

Edible and Functionalized Films/Coatings—Performances and Perspectives

et al. 2020

In recent years, food packaging has evolved from an inert and polluting waste that remains after using the product toward an active item that can be consumed along with the food it contains. Edible films and coatings represent a healthy alternative to classic food packaging. Therefore, a significant number of studies have focused on the development of biodegradable enveloping materials based on biopolymers. Animal and vegetal proteins, starch, and chitosan from different sources have been used to prepare adequate packaging for perishable food. Moreover, these edible layers have the ability to carry different active substances such as essential oils—plant extracts containing polyphenols—which bring them considerable antioxidant and antimicrobial activity. This review presents the latest updates on the use of edible films/coatings with different compositions with a focus on natural compounds from plants, and it also includes an assessment of their mechanical and physicochemical features. The plant compounds are essential in many cases for considerable improvement of the organoleptic qualities of embedded food, since they protect the food from different aggressive pathogens. Moreover, some of these useful compounds can be extracted from waste such as pomace, peels etc., which contributes to the sustainable development of this industry.

“…With the addition of plasticizer [ 16 ] and enhancer [ 1 , 17 , 18 ], the application of hemicellulose film became possible. However, the large number of hydrophilic hydroxyl groups make hemicellulose film susceptible to the absorption of moisture, resulting in poor performance when used in a humid environment [ 19 ]. Hemicellulose can be chemically modified by etherification [ 20 , 21 , 22 ], esterification [ 23 , 24 , 25 ], grafting [ 26 , 27 ], sulfonylation, and such [ 28 ], to improve the moisture resistance of hemicellulose films.…”

Barrier Film of Etherified Hemicellulose from Single-Step Synthesis

et al. 2020

Hemicellulose with good biodegradability and low oxygen permeability shows great potential in food packaging. However, its strong hydrophilicity leads to its poor moisture resistance, which hinders its wider application. In this paper, a near-hydrophobic hemicellulose was obtained by using single-step synthesis from poplar powder via etherification modification with epoxy chloropropane. This proposed approach has the advantage of avoiding the destruction of hemicellulose structure by secondary alkali-hydrolysis, which was what usually occurred in traditional etherification procedures. The feasibility of using epoxy chloropropane as an alkylation reagent to etherify hemicellulose was confirmed, and the reaction mechanism was elucidated. Contact angle test, thermogravimetric analysis, oxygen transmittance test, and infrared spectrum analysis showed that the barrier property and thermal stability of etherified hemicellulose films have been significantly improved. At an epoxy chloropropane/wood powder ratio (volume/weight) of 2/3 (mL/g), the epoxy hemicellulose films contained the most epoxy groups and displayed the best performance, i.e., tensile strength of 14.6 MPa, surface contact angle of 71.7° and oxygen transmission coefficient of 1.9 (cm3·µm)/(m2·d·kPa), showing great promise as barrier film in food-packaging.
