“…First, the synthesis conditions were optimized to obtain stable particle dispersions with a maximum solid content and appropriate viscosity [148]. These materials were applied by a bar-coating process onto paper and paperboard surfaces to study the chemical and morphological properties in relation with printability [149]. An important factor in this analysis, is the multiple-scale modeling of roughness parameters of the (coated) paper surfaces [150].…”

Abstract:The barrier resistance and wettability of papers are commonly controlled by the application of petroleum-based derivatives such as polyethylene, waxes and/or fluor-derivatives as coating. While surface hydrophobicity is improved by employing these polymers, they have become disfavored due to limitations in fossil-oil resources, poor recyclability, and environmental concerns on generated waste with lack of biodegradation. Alternatively, biopolymers including polysaccharides, proteins, lipids and polyesters can be used to formulate new pathways for fully bio-based paper coatings. However, difficulties in processing of most biopolymers may arise due to hydrophilicity, crystallization behavior, brittleness or melt instabilities that hinder a full exploitation at industrial scale. Therefore, blending with other biopolymers, plasticizers and compatibilizers is advantageous to improve the coating performance. In this paper, an overview of barrier properties and processing of bio-based polymers and their composites as paper coating will be discussed. In particular, recent technical advances in nanotechnological routes for bio-based nano-composite coatings will be summarized, including the use of biopolymer nanoparticles, or nanofillers such as nanoclay and nanocellulose. The combination of biopolymers along with surface modification of nanofillers can be used to create hierarchical structures that enhance hydrophobicity, complete barrier protection and functionalities of coated papers.

“…When stored under high humidity conditions or when in contact with high-moisture materials, they tend to absorb water vapour from the environment due to cellulose composition resulting in their reduced physical and mechanical strength 2 . The design of water-repellent barrier layers is essential for packaging materials made from porous and absorbent textiles, paper or paperboard 3 . Low barrier abilities against water vapor and gases are the main problems in food packaging.…”

“…The surface properties and wettability of those substrates can be influenced by physical (drying, calendaring) and chemical (impregnation, coating) treatments, forming a first barrier against water adsorption. Hydrophobic barrier coatings are most likely applied by means of extrusion, lamination or dispersion coating 3 . Many biopolymers are hygroscopic materials and can lose their barrier properties at high relative humidity (RH) due to water absorption 4 .…”

In this work, we studied the properties of printed paperboard samples coated with biodegradable PCL polymer, which was considered to overcome the disadvantages (barrier properties) of a paper-based material. Additionally, the samples were coated with PCL modified with SiO 2 and Al 2 O 3 nanoparticles. The characterization of the coated paperboard (with print) samples was made by determination of water vapor transmission rate (WVTR), contact angle of water and its evolution over time, and mechanical and visual properties. The samples were also examined by SEM microscopy. The results show that PCL and PCL coatings modified with SiO 2 and Al 2 O 3 nanoparticles slow down the water vapor transmission rate when compared to the paperboard without coatings. The water contact angle measurements show an increase in hydrophobicity in paperboard coated with PCL-SiO 2 , while PCL-Al 2 O 3 shows a decrease when compared to neat paperboard and paperboard coated with neat PCL. The studied coated samples also improve mechanical properties of paperboard while preserving the visual properties of print.

URRENTLY, styrene acrylate copolymers have highly been employed in paper coating application. In sequence to contribute to the green environment approach, different styrene acrylate copolymers with different pigment percentages were formulated and applied on recycled brown base paper in order to determine the most efficient coating. The study also investigated the applicability of Egyptian ground calcium carbonates in paper coating as an alternative of the traditional imported kaolin pigment. The effect of such binders on mechanical properties; water absorbency "Cobb60"; air permeability of paper; gloss and printability of coated paper was explored. The water absorption of coated papers was 30gm/m 2 compared with 35gm/m 2 for the commercial one. This means that ink consumption can be decreased by ≈30% in concert with the possibility of usage of low viscous ink. Gloss of coated papers was upgraded to more than double that of base ones. The burst strength; ring crush and the tensile strength for the coated papers were simultaneously improved compared with the commercial ones. The printability of coated papers was as well superior to the commercial one; this can evidently reduce the economical cost of the printing process.
