“…Addition of nanocomposite materials to polymer matrix is considered as an efficient method to alter the barrier properties of the packaging materials towards gas molecules such as oxygen, carbon dioxide and water vapour. As a result, it has been attempted to include such inorganic clay nanoplatelets into a polymer matrix in order to increase the gas barrier efficiency material 29 . Tas et al 30 reported a decrease in WVTR and OTR by 32% and 22% when 1% nanoclay was incorporated to PE films.…”

The improved barrier properties were due to the filling of the micropores in the matrix by nanoclay, thereby obstructing the gas and water vapour permeation.…”

The shelf life of the sugarcane juice ('Mandya' variety Co 62175), packed in highdensity polyethylene-based nanocomposite films, was investigated for 60 days with 15 different combinations and thickness of nanoclay and compatibilizer. To assess the product's stability, physicochemical, microbiological and sensory tests were performed at 15-day intervals. The bio-chemical quality attributes, namely, total sugars, pH, total soluble solids and overall acceptability scores, were found to decline with regard to storage period under ambient conditions. The pH, total soluble solids (TSS) and total sugar content varied from 5. .54 g/100, respectively. The microbial quality of the stored juice was found to be depended on the quantity of compatibilizer, nanoclay and thickness of the packaging film. Among the developed nanocomposite high-density polyethylene (HDPE) films, material E (with 2% and 5% of nanoclay and compatibilizer, with 100-μm thickness) and material G (with 6% and 5% of nanoclay and compatibilizer, with 100-μm thickness) showed better physiochemical stability with zero microbial population in the sugarcane juice.

“…As a result, food quality, nutrient, safety, and bioactive compound delivery are increased. The application of nanomaterials in the food packaging films and coatings is an emerging research field; however, various nanomaterials have been investigated, such as two-dimensional (2D) nanoclay and graphene, one-dimensional (1D) nanocellulose and nanotubes, and zero-dimensional (0D) nanodots (Li et al, 2018;Cui et al, 2020a;Barra et al, 2020;Ahankari et al, 2021;Nath et al, 2022). The resultant functional nanocomposite coatings exhibit enhanced functional properties demonstrating great potential for food packaging applications.…”

“…Nanoclays are natural or synthetic 2D nanoscale minerals consisting of a certain amount of aluminum, silica, iron, and magnesium (Bandyopadhyay and Ray, 2019;Bumbudsanpharoke and Ko, 2019;Nath et al, 2022). Nanoclays exist as the layered nanoplatelets showing a well-structured lamellar arrangement.…”

“…Each layer has a thickness of ~1 nm and a lateral size from hundreds of nanometers to a few micrometers. Nanoclays have been explored in the development of food packaging materials due to their high aspect ratio, high mechanical strength, and super barrier properties (Nath et al, 2022). One of the most common nanoclays in food packaging films and coatings is montmorillonite (MMT) (Souza et al, 2018).…”

Due to the inherent hydrophilic nature and porosity of the paper fibers, hydrophobic polymeric materials, waxes, and inorganic fillers have been widely utilized as coatings and fillers, respectively, on a fiber-based substrate. Coatings also impart oxygen, aroma, and oil barrier properties desirable for food packaging applications. In addition, coatings improve the functional properties and characteristics of paper, including reduced water absorbance, enhanced surface finish, gloss finish, printability, readability, dimensional stability of the substrate, and antimicrobial performance. Such functional properties are highly desirable for consumer packaging applications. However, such coatings may limit the repulpability, recyclability, biodegradability, and compostability of paper and paperboard. In addition, the contamination of the substrate by-product also limits the recyclability of the fiber-based substrates, and the paper, paperboard, or corrugated material ends up in landfill sites. This review focuses on bioderived, biodegradable, compostable, and functional organic, inorganic, and hybrid hydrophobic coatings, which promote the circular economy by improving the repulpability or reduces carbon footprints.
