Food packaging helps to protect food from being lost or wasted, nevertheless it is perceived as an environmental problem. The present study gives an overview of methods to assess the environmental sustainability of food packaging. Furthermore, we propose a methodological framework for environmental assessment of food packaging. There is a broad consensus on the definition of sustainable packaging, which has to be effective, efficient, and safe for human health and the environment. Existing frameworks only provide general guidance on how to quantify the environmental sustainability of packaging. Our proposed framework defines three sustainability aspects of food packaging, namely direct environmental effects of packaging, packaging-related food losses and waste, as well as circularity. It provides a list of key environmental performance indicators and recommends certain calculation procedures for each indicator. The framework is oriented towards the Product Environmental Footprint initiative and the Circular Economy Package of the European Union. Further research should develop a method to determine the amount of packaging-related food losses and waste. Moreover, future studies should examine the potential environmental benefits of different measures to make food packaging more circular.

Micro- and nanoplastic (pMP and pNP, respectively) release is an emerging issue since these particles constitute a ubiquitous and growing pollutant, which not only threatens the environment but may have potential consequences for human health. In particular, there is concern about the release of secondary pMP and pNP from the degradation of plastic consumer products. The phenomenon is well-documented in relation to plastic waste in the environment but, more recently, reports of pMP generated even during the normal use of plastic food contact materials, such as water bottles, tea bags, and containers, have been published. So far, a validated and harmonized strategy to tackle the issue is not available. In this study, we demonstrate that plastic breakdown to pMP and pNP can occur during the normal use of polyethylene (PE) rice cooking bags and ice-cube bags as well as of nylon teabags. A multi-instrumental approach based on Raman microscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and particular attention on the importance of sample preparation were applied to evaluate the chemical nature of the released material and their morphology. In addition, a simple method based on Fourier transform infrared (FT-IR) spectroscopy is proposed for pNP mass quantification, resulting in the release of 1.13 ± 0.07 mg of nylon 6 from each teabag. However, temperature was shown to have a strong impact on the morphology and aggregation status of the released materials, posing to scientists and legislators a challenging question: are they micro- or nanoplastics or something else altogether?

PurposeThis paper aims to provide a strategic review of the marketing function for a Cypriot company operating in the liquid food packaging industry (for reasons of confidentiality the name of the company is withheld). The paper focuses on the dairy market, where the company does not have a very strong market position, and illustrates how through an analysis of the environment (internal and external audit) the company's strategic direction and marketing plan can be designed more effectively.Design/methodology/approachThe paper adopts a case study approach with primary research through in‐depth interviews with managers of the company under investigation.FindingsThe paper concludes that, by undertaking to rectify its weak marketing function, the company can develop capabilities that will lead to a fully integrated relationship with all its customers and significantly improve its market share.Originality/valueThe value of the paper lies in providing a new case study that highlights the importance of making the marketing function a more market/consumer oriented process that bridges the gap between strategic change and industrial complexity and instability.

11th IFAC Symposium on Dynamics and Control of Process SystemsIncluding Biosystems DYCOPS-CAB 2016 — Trondheim, Norway, 6—8 June 2016 ; The determination of diffusivity of compounds that can be transferred from packaging into food products is a keystone to ensure consumer's safety. However, no clear guidelines exist as how the diffusion experiment should be designed in order to maximise the accuracy of the estimated parameter. With the perspective of optimal experimental design, a methodology to estimate the diffusivity of a migrating compound in a polymer is presented, both for global methods (that measure the overall concentration) and local methods (that measure the profile of concentration along the polymer thickness). To demonstrate the methodology, real experimental data (transfer of Uvitex OB from linear low-density polyethylene) are used, and the OED based methodology is benchmarked against other heuristics. It is seen that, although the OED methodology outperforms the rest of methodologies when good initial guesses are available, its performance becomes deteriorated when gross over- or underestimations of the true value are made ; The author would like to acknowledge the reviewers for very constructive comments that have contributed to improve this work.

Although governments have implemented regulations to inform consumers on important product properties and protect consumers from deceptive information, empirical research on how consumers perceive, interpret and experience food packages have shown frequently that consumers may be misled by how information is presented and packages are designed. While communication in some domains is strictly regulated (health), claims in other domains are largely free (nature) and do not require substantiation. Subtleties in wording, image use and image style may affect the impressions consumers form. To support consumer decision making, legislators should not only provide rules and regulations that are formally correct, but also consider the effects a message and the way it is communicated (e.g., content, typeface, size, use of images, stylistic features) may have on buyers. While it may be unclear how best to support desirable behaviours, companies that take social responsibility can build on our work to develop their strategy.

Herein, we fabricated a starch-based flexible coating for food packaging papers with excellent hydrophobicity and antimicrobial properties. FTIR (Fourier transform infrared) and XRD (X-ray diffraction) spectra revealed the homogeneous dispersion of the ZnO nanoparticles (NPs) in the composite film within 5% ZnO NP dosage. SEM (scanning electron microscope) and AFM (atomic force microscope) micrographs confirmed the increased roughness on the composite film with the increased dosages of ZnO NPs. Hydrophobic characteristics showed that dramatic enhancement was obtained in the values and stabilities of DCAs (dynamic contact angles) in the resultant film and coated paper. TG (thermogravimetry) results demonstrated the increased thermal stabilities of the composite films. Significantly, a decreased water vapor transmission rate was observed in the coated paper. When 20% guanidine-based starch and 2% CMC (carboxy methyl cellulose) was added, a flexible coating with excellent antimicrobial activity towards Escherichia coli can be obtained. Furthermore, the migration of ZnO NPs into the food simulants was well below the overall migration legislative limit. The resultant starch-based flexible composite film and coated paper established an effective approach to develop a green-based material for food packaging applications.

Polyethylene terephthalate (PET) is a polymer deemed safe to be mechanically recycled and used in food contact applications. Its recycled form (rPET) can be used as a food contact material (FCM). Although this is an obvious positive step towards a more circular economy, the development of an appropriate analytical toolbox to experimentally assess and evaluate the various steps during end of life and mechanical recycling is still at its infancy. The safety of the decontamination process is currently evaluated following a conventional modelling approach applied to a specific number of compounds (challenge test). However, additional compounds, quality markers and process controls are needed, with respect to migrating substances, potential non-intentionally added substances (NIAS), contaminants and known polymeric degrading compounds. This would ensure an additional level of safety and provide recomendations for the application of appropriate methods when ensuring full compliance with safety standards for rPET. This review presents the current regulatory framework and the most recent developments in analytical methodologies related to compliance testing. It also highlights some of most described chemical substances found in food-grade rPET.

The thermal stability of four different commercial citrus peel extracts was tested and improved by an encapsulation process with β-cyclodextrins in a spray-dryer. All extracts after the encapsulation process maintained a good antioxidant capacity, with an apparent loss in total phenolic compounds of around 20–25%. In addition, all samples showed good antimicrobial activity (MIC 5–0.625 mg/mL) against Staphylococcus aureus, which was maintained after the encapsulation process (MIC 5–1.25 mg/mL). Based on the antioxidant and antimicrobial activity results, the best-encapsulated citrus extract was selected for incorporation into a polylactic acid/polyhydroxy butyrate (PLA/PHB) film. The latter was then produced on an industrial scale by cast extrusion and was found to be suitable for food contact as it showed overall migration values in different food simulants lower than the legislative limit of 10 mg of non-volatile substances per 1 dm2 of surface area. The UHPLC-HRMS analysis, performed to evaluate the migration of the active compounds, revealed about 13.41% release in food simulant A and 11.02% in food simulant B. Antimicrobial analysis conducted directly on the film showed a growth inhibition activity towards Escherichia coli and Staphylococcus aureus equal to 30 and 60%, respectively.

Market implementation of active and intelligent packaging (AIP) technologies specifically for fiber-based food packaging can be hindered by various factors. This paper highlights those from a social, economic, environmental, and legislative point of view, and elaborates upon the following aspects mainly related to interactions among food packaging value chain stakeholders: (i) market drivers that affect developments, (ii) the gap between science and industry, (iii) the gap between legislation and practice, (iv) cooperation between the producing stakeholders within the value chain, and (v) the gap between the industry and consumers. We perceive these as the most influential aspects in successful market implementation at a socioeconomic level. The findings are supported by results from quantitative studies analyzing consumer buying expectations about active and intelligent packaging (value perception of packaging functions, intentions to purchase AIP, and willingness to pay more) executed in 16 European countries. Finally, in this paper, we discuss approaches that could direct future activities in the field towards industrial implementation.
