Nanocellulose has wide application prospects due to its abundant availability, low price, and biodegradability. In addition, it can address a number of environmental issues. For example, nanocellulose can be used as an alternative to petroleum to reduce environmental pollution. Moreover, nanocellulose has been used as a reinforcing material for food packaging. Improved barrier properties can be obtained when nanocellulose is combined with biopolymers and synthetic polymers. This review briefly introduces three types of nanocellulose and presents the recent advances in barrier property improvement using these three kinds of nanocellulose and their application in food packaging.

AbstractThis review deals with the evolution of bio-based packaging and the emergence of various nanotechnologies for primary food packaging. The end-of life issues of packaging is discussed and particularly the environmental problems associated with microplastics in the marine environment, which serve as a vector for the assimilation of persistent organic pollutants in the oceans and are transported into the food chain via marine and wild life. The use of biodegradable polymers has been a primary route to alleviate these environmental problems, but for various reasons the market has not developed at a sufficient pace that would cope with the mentioned environmental issues. Currently, the biodegradable plastics only constitute a small fraction of the fossil-based plastic market. Fossil-based plastics are, however, indispensable for food safety and minimization of food waste, and are not only cheap, but has generally more suitable mechanical and barrier properties compared to biodegradable polymers. More recently, various nanotechnologies such as the use of nanoclays, nanocellulose, layer-by-layer technologies and polyelectrolyte complexes have emerged as viable technologies to make oxygen and water vapor barriers suitable for food packaging. These technological developments are highlighted as well as issues like biodegradation, recycling, legislation issues and safety and toxicity of these nanotechnologies.

Nowadays, environmental pollution due to synthetic polymers represents one of the biggest worldwide challenges. As demonstrated in numerous scientific articles, plant-based nanocellulose (NC) is a biodegradable and nontoxic material whose mechanical, rheological, and gas barrier properties are competitive compared to those of oil-based plastics. However, the sensitivity of NC in humid ambient and lack of thermosealability have proven to be a major obstacle that hinders its breakthrough in various sectors including food packaging. In recent years, attempts have been made in order to provide a hydrophobic character to NC through chemical modifications. In addition, extensive works on nanocellulose applications in food packaging such as coating, layer-by-layer, casting, and electrospinning have been reported. Despite these enormous advances, it can easily be observed that packaging manufacturers have not yet shown a particular interest in terms of applicability and processability of the nanocellulose due to the lack of guidelines and guarantee on the success of their implementation. This review is useful for researchers and packaging manufacturers because it puts emphasis on recent works that have dealt with the nanocellulose applications and focuses on the best strategies to be adopted for swift and sustainable industrial manufacturing scale-up of high-performance bio-based/compostable packaging in replacement of the oil-based counterparts used today.

Abstract Today, there is an increasing concern about protection of ecological systems. Petro-based synthetic polymers are not biodegradable and cause environmental pollution. These polymers that are stuck in nature, affect wildlife adversely. Also, in future petrochemical materials will drain away and demand for eco-friendly plastics which can substitute synthetic plastics will increase. Biopolymers are products which can be degraded by enzymatic activities of various microorganisms, and the degradation products are nontoxic. They are attractive alternatives to non-degradable materials in short-term applications such as packaging. Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a member of polyhydroxyalkanoate (PHA) family which is biodegradable and produced by microorganism. It has good gas barrier properties that make it convenient to use in different applications. The present paper gives an overview on PHAs and their composites, their main properties, with a specific focus on potential applications of PHBV in packaging.

Petroleum-based synthetic polymers are mostly used for packaging materials for their advantageous features such as flexibility, lightness and transparency. However, the waste caused by the increasing usage has led to serious environmental impacts. There are many packaging products claimed as ‘green’ material in the market but, they are not fully from natural renewable resources. Most biocomposites materials comprised only either the matrix or fiber/filler from natural renewable resources, but still blended with another synthetic compound. Thus, green biocomposites which composed of fully biodegradable natural fibers and biopolymer matrix would be a great alternative. It can be naturally degraded and completely return to the environment safely after usage. The main shortcomings of biopolymer are their inadequate of mechanical and barrier properties in product application. Yet, the embedding reinforcing fibers or fillers would help in improving the final properties of the composites. The intention of this review is to present the latest development of green biocomposites research and its application for food packaging. It is also proposed to provide critical information that covers around properties of green biocomposites, types of available biopolymers and natural fibers, including their manufacturing techniques. Furthermore, the economic circumstances and forthcoming trend of these materials in food packaging industry would also be reviewed

Climate change, tropical deforestation, biodiversity loss, ozone depletion, hazardous wastes, and ocean pollution are among the environmental issues that have bought national governments together in a common purpose. As they have worked to mitigate these global problems, national governments have developed a wide variety of environmental regime designs. They have created complex systems of global rules and institutions to enable and incentivize private and public actors to meet the challenges posed by global pollution. Why have national governments created different international rules and institutions to address global environmental issues? This book demonstrates that national governments have developed different institutional responses to global issues because the markets producing environmental pollution impose varying constraints and create varying opportunities for change. The nature and scale of those constraints and opportunities depend on the capital resources and industrial concentrations of producers and the demand characteristics of consumers in the markets that governments seek to regulate. Global institutions are designed to match the basic elements of the markets producing global environmental pollution. In global governance, not only are oligopolistic businesses politically influential in shaping policy outcomes, but they are also efficient implementers of environmental regulation. They face a double-edged sword arising from their wealth and market concentrations. Although they are able to shape regulatory policy, these powerful businesses are targeted for stringent global regulation. The sources of their political influence make them the best options for mitigating global pollution.

Ferula Asafoetida

The physical, thermal, mechanical, optical, microstructural, and barrier properties of low-density polyethylene films (LDPE) containing ferula asafoetida leaf and gum extracts were investigated. Results showed a reduction in elasticity and tensile strength with increasing extract concentration in the polymer matrix. The melting temperature and enthalpy increased with increasing concentration of extracts. The films containing extracts had lower L∗ and a∗ and higher b∗ indices. The films containing leaf extract had more barrier potential to UV than the gum extracts. The oxygen permeability in films containing 5% of leaf and gum extracts increased by 2.3 and 2.1 times, respectively. The morphology of the active films was similar to bubble swollen islands, which was more pronounced at higher concentrations of gum and leaf extracts. FTIR results confirmed some chemical interactions of ferula extracts with the polymer matrix. At the end of day 14th, the growth rate of Aspergillus niger and Saccharomyces cerevisea in the presence of the PE-Gum-5 reduced more than PE-Leaf-5 (3.7 and 2.4 logarithmic cycles, respectively) compared to the first day. Our findings showed that active LDPE films have desire thermo-mechanical and barrier properties for food packaging.
