Packaging is an essential element of response to address key challenges of sustainable food consumption on the international scene, which is clearly about minimizing the environmental footprint of packed food. An innovative sustainable packaging aims to address food waste and loss reduction by preserving food quality, as well as food safety issues by preventing food-borne diseases and food chemical contamination. Moreover, it must address the long-term crucial issue of environmentally persistent plastic waste accumulation as well as the saving of oil and food material resources. This paper reviews the major challenges that food packaging must tackle in the near future in order to enter the virtuous loop of circular bio-economy. Some solutions are proposed to address pressing international stakes in terms of food and plastic waste reduction and end-of-life issues of persistent materials. Among potential solutions, production of microbial biodegradable polymers from agro-food waste residues seems a promising route to create an innovative, more resilient, and productive waste-based food packaging economy by decoupling the food packaging industry from fossil feed stocks and permitting nutrients to return to the soil. To respond to the lack of tools and approach to properly design and adapt food packaging to food needs, mathematical simulation, based on modeling of mass transfer and reactions into food/packaging systems are promising tools. The next generation of such modeling and tools should help the food packaging sector to validate usage benefit of new packaging solutions and chose, in a fair and transparent way, the best packaging solution to contribute to the overall decrease of food losses and persistent plastic accumulation.

Polymer-based multilayer packaging materials are commonly used in order to combine the respective performance of different polymers. By this approach, the tailored functionality of packaging concepts is created to sufficiently protect sensitive food products and thus obtain extended shelf life. However, because of their poor recyclability, most multilayers are usually incinerated or landfilled, counteracting the efforts towards a circular economy and crude oil independency. This review depicts the current state of the European multilayer packaging market and sketches the current end-of-life situation of postconsumer multilayer packaging waste in Germany. In the main section, a general overview of the state of research about material recycling of different multilayer packaging systems is provided. It is divided into two subsections, whereby one describes methods to achieve a separation of the different components, either by delamination or the selective dissolution–reprecipitation technique, and the other describes methods to achieve recycling by compatibilization of nonmiscible polymer types. While compatibilization methods and the technique of dissolution–reprecipitation are already extensively studied, the delamination of packaging has not been investigated systematically. All the presented options are able to recycle multilayer packaging, but also have drawbacks like a limited scope or a high expenditure of energy.

Abstract Background The ever-growing world population results in the ineluctable increase of food demand which translates in the augment of the global market of packaging materials. Hence, the concept of active packaging materializes as a technology to enhance the safety, quality and shelf-life of the packaged foods. Active packaging systems can contribute to the reduction of food waste by providing, apart from an inert barrier to external conditions, several functions associated with food preservation, namely absorbing/scavenging, releasing/emitting and removing properties, temperature, microbial and quality control. Scope and approach The purpose of this review is to present a concise (but wide-ranging) appraisal on the latest advances in active agents for active food packaging. Emphasis is placed on active functions such as antimicrobial and antioxidant activity, oxygen and ethylene scavenging, and carbon dioxide emitting. An effort was made to highlight representative articles that prompted research on active agents towards viable market solutions. Key findings and conclusions Active packaging is a thriving field given its duality as barrier to external detrimental factors and active role in food preservation and quality. The use of natural active agents is a flourishing field due to the general concern towards natural-based additives. Nevertheless, research is still in its early stages with a long way to go in the design of innovative and economical active packaging materials containing appropriate active agents. The interaction between packaging, environment and food is the key challenge for achieving commercial translation.

Abstract Most of the scientific studies and innovations in food packaging have focused on the inhibition or prevention of microbial growth as well as avoiding further microbial deterioration of food products. Among current food packaging techniques, active packaging, particularity antimicrobial active packaging, has attracted much attention due to the diversity in the materials used, the methods of application, and the variety of food products that can be protected. Direct and indirect techniques can be utilized to introduce antimicrobial compounds into food packaging materials. The increasing importance of the application of antimicrobial packaging has inspired a better understanding of these materials and the factors influencing the effectiveness of antimicrobial systems. This article is a review on the materials used for delivering antimicrobial substances with a focus on their main mechanisms of action and release when used for food contact applications. In this regard, the effects of antimicrobial agents on packaging properties will be discussed. Many challenges, including the controlled release of antimicrobial agents and the development of active packaging materials (mainly bio-based materials) with adequate barrier properties, transparency, tensile strength and other characteristics to meet the requirements of food protection and food safety, still remain to be solved in these new approaches to antimicrobial active packaging.

Spoilage of meat products during processing, distribution and exposure in the markets have an important negative impact on meat industry from an economic point of view. Two of the main problems of meat and products during processing and subsequent storage are lipid oxidation and deterioration due to microorganism growth. In this context, several packaging alternatives have been developed by meat industry in order to limit these losses and to extend the meat products´ shelf life. Over the last years, the use of active packaging has been proposed as an alternative to traditional packaging. The principle of active packaging, particularly antioxidant active packaging, consists of including active agents in the packaging which interact with meat and/or its environment, either by trapping pro-oxidant compounds or by releasing antioxidant compounds in order to delay degradation due to lipid oxidation. Therefore, the use of active packaging is presented as a future option to solve the problems derived from oxidative deterioration of meat and meat products. However, its use will depend on the costs involved in the development of this active packaging. Therefore, this review will give an overview about the use of active packaging and natural antioxidants, the active film development techniques, as well as the use of biopolymers as substitutes for synthetic polymers and their direct application in the meat industry.

Poly(lactic acid) (PLA) is the most used biopolymer for food packaging applications. Several strategies have been made to improve PLA properties for extending its applications in the packaging field. Melt blending approaches are gaining considerable interest since they are easy, cost-effective and readily available processing technologies at the industrial level. With a similar melting temperature and high crystallinity, poly(hydroxybutyrate) (PHB) represents a good candidate to blend with PLA. The ability of PHB to act as a nucleating agent for PLA improves its mechanical resistance and barrier performance. With the dual objective to improve PLAPHB processing performance and to obtain stretchable materials, plasticizers are frequently added. Current trends to enhance PLA-PHB miscibility are focused on the development of composite and nanocomposites. PLA-PHB blends are also interesting for the controlled release of active compounds in the development of active packaging systems. This review explains the most relevant processing aspects of PLA-PHB based blends such as the influence of polymers molecular weight, the PLA-PHB composition as well as the thermal stability. It also summarizes the recent developments in PLA-PHB formulations with an emphasis on their performance with interest in the sustainable food packaging field. PLA-PHB blends shows highly promising perspectives for the replacement of traditional petrochemical based polymers currently used for food packaging.

Abstract Mango peels extract (MPE) was incorporated into fish gelatin films to determine their physical, barrier, mechanical and antioxidant properties for active food packaging. Films with three different concentrations of MPE (1–5%) were prepared by solution casting method. Films incorporated with MPE showed a decrease (P > 0.05) of water vapor permeability (WVP) and lower (P ≤ 0.05) films solubility. High level of MPE films also exhibited more rigid and less flexible film formation. Colored tint films and a reduction in transparency were due to the hydrogen bond linkages between fish gelatin molecules and phenolic content within the film matrix. Higher free radicals scavenging activities also observed for films with higher concentrations of MPE. This study reveals the benefits of mango by-products incorporated into gelatin based films as a potential material for active packaging.

Edible films are increasingly recognized as promising sustainable packaging alternatives, but often face challenges such as poor mechanical strength, limited barrier properties, and low oxidative stability. This study aimed to enhance the physicochemical performance of collagen fiber–starch composite films by incorporating polyphenols (including tannic acid (TA), caffeic acid (CA), and their oxidized forms, OTA and OCA) as natural cross-linkers and antioxidants. Results showed that the addition of 0.1% TA increased the tensile strength by approximately 45% compared to the control, while simultaneously reducing the water vapor permeability from 1.32 to 1.26 g·mm/kPa·h·m², with TA outperforming CA due to its higher molecular weight and stronger intermolecular interactions. Oxidized polyphenols further improved the mechanical and water vapor barrier properties via quinone-induced covalent cross-linking, thereby forming a denser film network. The films also exhibited enhanced UV–visible light shielding, with nearly complete ultraviolet blockage (transmittance is close to zero in the 200–280 nm range). Non-oxidized polyphenols showed higher antioxidant activity in the ABTS and reducing power assays, while release kinetics analysis revealed the highest release rate in 50% ethanol, indicating a pronounced solvent-dependent behavior. Specifically, films with 0.1% TA exhibited an ABTS radical scavenging activity of over 80%, significantly higher than the control. Overall, polyphenols effectively improve film performance through cross-linking and structural modification, offering a theoretical foundation for designing active packaging for targeted food systems.

Abstract With the growing popularity of worldwide environmental protection and the concept of sustainable development, eco-friendliness has become the trend of the times. In this regard, green packaging has received increasing attention in the logistics industry. Therefore, to promote the development of green packaging in China, it is of key importance to know consumers’ cognition and willingness to pay for it. In this study, the data of 781 respondents from a carefully designed survey is used to analyze the influential factors of consumers’ willingness to pay for green packaging. By employing the principal factor analysis method, four principal factors affecting consumers’ willingness to pay are uncovered: environment, green packaging quality, commodity, and packaging price. According to the estimation results, even though the majority of consumers have insufficient certain knowledge regarding green packaging, they have a fairly strong willingness to pay for it. Additionally, we observed that compared with the price and appearance of green packaging, consumers would like to attach greater importance to the practicality of green packaging, such as convenience, reusability, and protective capability.

Hydrogels are three-dimensional, hydrophilic networks, comprising polymeric chains linked through physical or chemical bonds. In the area of food, hydrogels have great potential to be used in food packaging systems or as carriers of bioactive components. This paper reviews the nature of hydrogels, their 3D network conformation, their functional properties, and their potential applications in food packaging systems. Regarding their potential food packaging applications, hydrogels can present a conformation which allows their use as part of a packaging system to control the humidity generated by food products with high water content. Moreover, the incorporation of nanoparticles into hydrogels may grant them antimicrobial activity. Finally, although the current research in this field is still limited, the results obtained so far are promising for innovative and potential applications in the food field, which also include their integration into intelligent food packaging systems and their direct incorporation into food matrices as a flavor carrier system.

Objectives This qualitative study explored public and prescriber awareness of pharmaceutical pollution in the water environment and eco-directed sustainable prescribing (EDSP) as a mitigation strategy to reduce the environmental impact of prescribing in Scotland.Design Focus groups explored prescriber and public perceptions of the topic. Common questions were asked through semistructured facilitation. Focus groups were digitally recorded and transcribed verbatim using an artificial intelligence system, then anonymised and thematically analysed using NVivo software. Data were iteratively analysed using the one sheet of paper technique.Setting Public focus groups were held in-person (Inverness, Scotland, April 2023), and prescriber focus groups were held virtually (MS Teams, August 2023).Participants Nine public representatives and 17 NHS Scotland prescribers participated in one of four focus groups. Purposive and opportunistic sampling approaches were used to recruit participants through social media and other channels (ie, community groups, professional emails, general practitioner and hospital flyers). Prescriber representatives registered interest through an online survey to gather information about their professional background. Responses were reviewed to ensure representation of a mixture of medical backgrounds, experience, sectors and health boards.Results There is growing awareness among the public and healthcare professionals of pharmaceutical pollution in the environment, but further education is required on the drivers, potential effects and possible interventions. Suggestions for more sustainable healthcare included public health awareness campaigns, better provision for pharmacy take-back schemes, clear medicine/packaging labelling, regular medicines reviews and more considered patient-centred care. From the prescriber perspective, EDSP resonated well with current sustainability initiatives (eg, Realistic Medicine, switching to dry-powder inhalers), but barriers to EDSP included lack of knowledge, confidence, time and resources to implement changes. Although the public representatives were generally open to the concept of EDSP, this decision required weighing pros/cons considering personal health choices, information accessibility and transparency, and trust in and time with prescribers.Conclusions This study identified new insights from prescribers and the public related to the concept of, and barriers to, EDSP in Scotland, as well as perspectives regarding knowledge support tools and information communication. Cross-sector and transdisciplinary collaborative approaches are needed to address the challenges identified here. Nonetheless, EDSP merits further exploration in developing more sustainable, appropriate and effective healthcare which contributes to improved public and planetary health.
