Recycled Plastics

The European strategy for plastics, as part of the EU’s circular economy action plan, should support the reduction in plastic waste. One key element in this action plan is the improvement of the economics and quality of recycled plastics. In addition, an important goal is that by 2030, all plastics packaging placed on the EU market must either be reusable or can be recycled in a cost-effective manner. This means that, at the end, a closed-loop recycling of food packaging materials should be established. However, the use of recyclates must not result in less severe preventive consumer protection of food packaging materials. This may lead to a conservative evaluation of authorities on post-consumer recyclates in food packaging applications. On the other hand, over-conservatism might over-protect the consumer and generate insurmountable barriers to the application of post-consumer recyclates for food packaging and, hence, counteract the targets of circular economy. The objective of this review is to provide an insight into the evaluation of post-consumer recyclates applied in direct contact to food. Safety assessment criteria as developed by the European Food Safety Authority EFSA will be presented, explained, and critically discussed.

Safe food packaging is of great significance in solving food safety problem, which can ensure the quality of the food. At the same time protecting the environment should be taken into consideration, and therefore sound food packaging is not only safe to human health but also green to the environment. In this paper potential safety hazards in food packaging materials and how to develop green food packaging are discussed at length.

One of the storage conditions affecting quality of food stuffs due to short shelf life is temperature. Thermal insulation can be achieved by adding phase change materials (PCMs) to packaging materials. PCMs store and release latent heat of phase change during melting and crystallization operations, respectively. Thus, they can provide thermal protection for packaged foods. The aim of this study is to prepare new food packaging materials poly (ethylene terephthalate)–poly (ethylene glycol) (PET–PEG) multiblock copolymers as solid–solid phase change materials (SSPCM) as potential food packaging materials with thermal energy storage (TES) property. Polyesterification was carried out with PEG at different average molecular weights (1000, 4000 and 10,000 g/mol), ethylene glycol (EG) and terephthaloyl chloride (TPC). Synthesized PET–PEG multiblock copolymers were characterized using Fourier transform infrared (FT-IR) spectroscopy and differential scanning calorimetry (DSC) methods. The crystal structures of PET–PEG multiblock copolymers were characterized by polarized optical microscopy (POM) and their surface properties were determined by performing contact angle tests. TES capacity of the PET–PEG multiblock copolymers was found in range of 26.1–150.5 J/g. Consequently, this study demonstrates the potential of PET–PEG multiblock copolymers suitable for effective thermal preservation in packaging material applications to maintain the quality of packaged food stuffs.

The development of sci-tech has promoted the institutionalization of life, food safety is a subsystem of life, and it is a huge task to ensure food safety, which thus jointly puts forward new requirements for packaging technology, especially for package materials. Nowadays, the existing food packaging materials are more and more unsatisfying, and it is hoped that the packaging materials can extend the period of use of foods and ensure no extrusion on foods in the transport process, and the consumption of packaging materials can be reduced to save resources. In this paper, the consumers psychology, the purpose of packaging and corresponding requirements raised for packaging materials are analyzed, then development trend of packaging materials is explored.

And Migration

With the rapid development of materials science, polymers are widely used in food packaging. Because the polymer modification process can lead to the formation of low molecular weight compounds, these substances which migrate from packaging materials to food bring many hidden dangers to food safety and threaten peoples health. In order to ensure the safety of food packaging materials, it is necessary to completely study and discuss the migration process of low molecular weight compounds, and then take effective methods to control the pollutants. The real process of polymer components in food package migration is quite complex, which is affected by many non-ideal factors. If we simply analysis the migration model, the actual results could not be got. We use migration model combining with the methods of modern analysis instruments on the basis of migration model, the model will have more practical application. The paper is based on migration theory and migration model. Under the existing experimental conditions, truly simulate the migration process of food packaging materials by using modern analytical measurement instruments and experimental simulation tools. Combine the theory and practice, analyze the migration and migration influencing factors of PS extract from qualitative and quantitative aspects. It is of great practical significance in solving the food safety problems which caused by migration from food packaging materials.

There is a strong drive in industry for packaging solutions that contribute to sustainable development by targeting a circular economy, which pivots around the recyclability of the packaging materials. The aim is to reduce traditional plastic consumption and achieve high recycling efficiency while maintaining the desired barrier and mechanical properties. In this domain, packaging materials in the form of polymer nanocomposites (PNCs) can offer the desired functionalities and can be a potential replacement for complex multilayered polymer structures. There has been an increasing interest in nanocomposites for food packaging applications, with a five-fold rise in the number of published articles during the period 2010–2019. The barrier, mechanical, and thermal properties of the polymers can be significantly improved by incorporating low concentrations of nanofillers. Furthermore, antimicrobial and antioxidant properties can be introduced, which are very relevant for food packaging applications. In this review, we will present an overview of the nanocomposite materials for food packaging applications. We will briefly discuss different nanofillers, methods to incorporate them in the polymer matrix, and surface treatments, with a special focus on the barrier, antimicrobial, and antioxidant properties. On the practical side migration issues, consumer acceptability, recyclability, and toxicity aspects will also be discussed.
