“…Having a 2: 1 phyllosilicate (an Al-O octahedral layer sandwiched between two Si-O tetrahedral layers), these particles have intrinsic hydrophilicity. [6,8,9,11,17,18]. Kaolin, on the other hand, is a 1: 1 phyllosilicate clay composed of an octahedral gibbsite layer and a tetrahedral silicon oxide layer.…”

Hybrid paper sheets were prepared by applying a thin coating layer of cross-linked polydimethylsiloxane (PDMS) and inorganic particles onto Whatman Grade 1 filter paper substrates. Several coatings with different inorganic particle contents and types were applied onto the paper substrates to investigate the effect of the variation in the coating formulation on the (i) wetting, (ii) water barrier properties, (iii) air barrier properties, (iv) surface roughness, and (v) mechanical properties of the samples. It was revealed that the superhydrophobic hybrid paper sheets with significantly low air permeability and high water barrier properties could be prepared which is an indication that the method proposed can be used for the preparation of packaging materials.

“…When the number of coating layers rose to 10, a fully covered surface, with several small CS/CNC aggregates, was apparent from AFM images. To improve the moisture barrier properties for chitin or cellulose-based multilayer coating on paper, Li et al [83] prepared polymer-nanoclay hybrid multilayers consisting of quad-layers (QL) of carrageenan (CR)/CS/MMT/CS through LBL assembly. The original paper had a high WVTR value of 2903 g m −2 day −1 , which was attributed to the porous structure of cellulose fiber networks and hydrophilic characteristics.…”

The accumulation of synthetic plastics used in packaging applications in landfills and the environment is a serious problem. This challenge is driving research efforts to develop biodegradable, compostable, or recyclable barrier materials derived from renewable sources. Cellulose, chitin/chitosan, and their combinations are versatile biobased packaging materials because of their diverse biological properties (biocompatibility, biodegradability, antimicrobial properties, antioxidant activity, non-toxicity, and less immunogenic compared to protein), superior physical properties (high surface area, good barrier properties, and mechanical properties), and they can be assembled into different forms and shapes (powders, fibers, films, beads, sponges, gels, and solutions). They can be either assembled into packaging films or used as fillers to improve the properties of other biobased polymers. Methods such as preparation of composites, multilayer coating, and alignment control are used to further improve their barrier, mechanical properties, and ameliorate their moisture sensitivity. With the growing application of cellulose and chitin-based packaging materials, their biodegradability and recyclability are also discussed in this review paper. The future trends of these biobased materials in packaging applications and the possibility of gradually replacing petroleum-based plastics are analyzed in the “Conclusions” section.

“…As a complement to the properties of biopolymers regarding barrier, reinforcements on a nanometric scale appear as co-adjuvants for they provide considerable gains even when used in low concentrations. Nanoclays, nanocellulose, and plant nanofibers, for example, have been studied in order to improve mechanical properties, microbial activities, barrier increase, and thermal behavior [27][28][29].…”

Polymer materials are used in several industrial sectors such as, paints and varnishes, packaging, and the automotive sector. The countless applications of this type of material stem from several factors such as lightness and ease of processing when compared to metals and ceramics. The possibility of chemical modification of polymers is worth mentioning, which can result in a new material with mechanical properties superior to those of the original ones. Another unique characteristic of polymer material is related to the ease with which they can be mixed with other elements (vegetable and synthetic fibers, metals, ceramics) to obtain a composite or hybrid material, thus expanding the spectrum of polymer applications. In this sense, the present work aims to show the uses of polymers in the packaging segment, addressing the main physicochemical and mechanical characteristics that are necessary for manufacturing packaging items as well as innovative technologies to obtain those materials.
