“…An improvement in the tensile properties was also seen with an increasing concentration of PHB over the paper surface. When PHB was coated over paperboard by compression molding, similar results were obtained in terms of improved barrier and mechanical properties, which were further enhanced when the paperboard was acetylated to have better adhesion between the PHB coating and the paperboard [37]. The PHB can also be used as a surface sizing agent to improve the barrier and mechanical properties of papers, where P(3HB) as homopolymer and P(3HB-co-3HV) as copolymer were introduced as granular suspensions of 1 and 0.2 μm, respectively [76]: after subsequent heat pressing the sized papers at 160 °C, the PHB granules melt and form a thin hydrophobic layer covering the fibers, resulting in an improvement of water resistance and tensile strength.…”

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.

“…Indeed PHB, which is the most common PHA, has water vapour permeability of about 0.03 g m/(m 2 day atm) and a liquid water solubility of about 0.02 g/g pol (Miguel & Iruin, 1996;Kamaev, Iordanskii, & Startsev, 1999;Shogren, 1997;Khwaldia, Arab-Tehrany, & Desobry, 2010;Cyras, Soledad & Analia, 2009), so the properties of these cups will likely be in between those observed for the two previous cups. The water vapour permeability will be approximately the same as that of the PE coated cup while the solubility will be in the range of that observed for PLA and the mechanical properties are quite sufficient for the application.…”

Paper and paperboard are the most widely used packaging materials for both food and non-food products. Because they are composed of highly porous cellulose networks, they readily absorb moisture in high humidity environments or when in contact with liquid or high moisture foods. Therefore they are often coated with hydrophobic coating materials such as polyethylene (PE) to improve their water-resistant properties. One of the major uses of such hydrophobic material coated paperboard is a disposable single-use paper cup with or without a lid. Today, the paper-based materials are coated with a thin layer of a petroleum derived plastic, mostly polyethylene, which has provided the cups and other packaging solutions with the required barrier property and water resistance. Hence, the ongoing challenge is to coat the paper with a biobased, hydrophobic polymeric material which must be repulpable or otherwise biodegradable in most of the environments considered.Many interesting developments are already known for the manufacturing of cellulose-based products, such as microfibrillated celluloses (MFC's) or modified celluloses, usable in the paper packaging industry. Paper and paperboard in combination with Green-Polyethylene, MFC's and polyhydroxyalkanoates (PHA's) seems to be the most promising solution for the packaging industry in the near future and the development of the thermoplastic modified celluloses for the next future. Regarding environmental considerations, PHA is a promising solution for the paper packaging industry but the problem of material recycling has to be solved and a solution comparable with the recyclability of PE-coated paper packaging products should be obtained.This review consists of a critical analysis of published results of 1-way food packaging and discusses more in detail what will be necessary for the development of 1-way food packaging based solely on wood derived products and biodegradable polymers.

“…Potentially positive properties of PHB and PHBV films with respect to food packaging applications are water vapor permeability (similar to that of PVC or PET [115][116][117][118][119] ), non-swelling behavior, and lower hydrophilicity (compared to other biopolymers e.g., cellulose, starch, chitosan and gluten) 115 . Besides, solubility and diffusivity of water in PHAs is a key factor for their degradation via enzymatic or non-enzymatic hydrolysis [120][121][122] .…”

The environmental impact of plastic usage is of critical concern and too great to repair. A shift toward biodegradable food packaging is one option. The aim of this review paper is the study of the potential of biodegradable materials for food packaging. The main characteristics in relation to food usage can be narrowed down to mass transfer (gas and water vapor), thermal and mechanical properties. Among several kinds of biodegradable polymers, poly(hydroxyalkanoate) is one of the favorable candidates for food packaging due to its physical and mechanical properties, biodegradability, with low permeability for O 2 , H 2 O and CO 2 without residues of catalysts and water solubility. The main focus of this article is to address poly(hydroxyalkanoate) as a potential candidate for food packaging. The need of applying biobased polymers in food packaging is presented in the introduction of this study. We also describe the most common biopolymers providing a brief overview of classification and application. This is followed by an outline of biopolymer production and a main section in which the properties of poly(hydroxybutyrate)-based nanocomposites of greatest relevance to food packaging are discussed. Furthermore, several approaches for improvement of poly(hydroxybutyrate) properties are described and the role of nanotechnology to improve its mechanical properties is presented. Finally, the article concludes with a summary as well as some possible future trends.
