Tidskriftsartikel (refereegranskat)abstract
- The localized deformation patterns developed during in-plane compression and folding of paperboard have been studied in this work. X-ray post-mortem images reveal that cellulose fibres have been reoriented along localized bands in both the compression and folding tests. In folding, the paperboard typically fails on the side where the compressive stresses exists and wrinkles are formed. The in-plane compression test is however difficult to perform because of the slender geometry of the paperboard. A common technique to determine the compression strength is to use the so-called short-span compression test (SCT). In the SCT, a paperboard with a free length of 0.7 mm is compressed. Another technique to measure the compression strength is the long edge test where the motion of the paperboard is constrained on the top and bottom to prevent buckling. A continuum model that previously has been proposed by the authors is further developed and utilized to predict the occurrence of the localized bands. It is shown that the in-plane strength in compression for paperboard can be correlated to the mechanical behaviour in folding. By tuning the in-plane yield parameters to the SCT response, it is shown that the global response in folding can be predicted. The simulations are able to predict the formation of wrinkles, and the deformation field is in agreement with the measured deformation pattern. The model predicts an unstable material response associated with localized deformation into bands in both the SCT and folding.

- The global challenges posed by demographic change call for more senior-friendly medication packaging. This paper presents a comprehensive integrated view and synthesis of the literature on medication packaging and older people. Considering the multidisciplinary nature of the research field, a systematic review was conducted in four databases (Scopus, Web of Science, Medline and Engineering Village), limited to original research studies containing empirical data and English-language papers, published until January 2015. Manual reference mining was carried out for other relevant papers, and a critical appraisal methodology was applied to judge the quality of the papers. In total, 34 studies are fully reviewed and classified according to the main characteristics of the studies, information about older patients and impact of the packaging on medication use. As a result, the review indicates the literature to be fragmented and diverse yet composed of two major interconnected research streams (physical functionality and user capability; medication management) and orientations (packaging; user). The physical functionality and user capability stream of research with a packaging orientation addresses child-resistant containers (CRCs), whereas the user-oriented studies address openability, i.e. the ease of opening the medication. In contrast, the medication management stream of research with a packaging orientation focuses on the adherence outcomes of different package aids, whereas the user-oriented studies focus on the counselling provided by healthcare professionals and coping strategies for older patients to handle the packages. These original findings provide valuable input to researchers and practitioners and offer guidance for the further development of medication packaging.

Tidskriftsartikel (refereegranskat)abstract
- Recent years have shown a shift in the focus of sustainable development from eco-efficiency (minimizing negative impacts) towards eco-effectiveness (optimizing positive impacts). Currently, a focus on circular models can be identified; Cradle to Cradle and circular economy are main examples of such models. However, the current number and variety of models and tools focusing on circular systems are limited with regard to packaging development. This paper explores packaging development models and tools in relation to circular systems, in order to identify the current status of the circularity focus. A range of identified models and tools is structured into two categories (generative and evaluative tools) which cover three types (protocols, diagrams and evaluations). This is in line with the distinction between early and later phases of development and the cumulative nature of environmental lock-in. Protocol-type models and tools come in different forms, such as principles, guidelines and checklists (e.g. Cradle to Cradle and DfE). Aside from these, eight diagram-type models are analysed, focusing on packaging development, sustainable development and sustainable packaging development. In contrast to generative design tools, evaluation-type models and tools (e.g. LCA) are most useful in the later stages of development processes. Resulting from the analysis of the models and tools, three types of integration - integrated product-packaging development, the cross-functional integration of actors and the front-end integration of sustainability considerations - are appropriate for the development of product-packaging combinations for circular systems. This leads to an agenda which shapes research directions towards achieving this development. (C) 2016 The Authors Packaging Technology and Science Published by John Wiley amp; Sons, Ltd.

Tidskriftsartikel (refereegranskat)abstract
- Corrugated package designers are focused on balancing the need for product protection, material use efficiency and the packaging material's impact on the environment in the supply chain. The purpose of this paper is to develop a conceptual sustainable packaging model that integrates the variables of technical design, supply chain systems and environmental factors and then use the model to identify to improve upon corrugated container design. A model was developed, from the extant literature, and a case study was performed on a corrugated container. This is believed to be a unique integrated model of most relevant agents related to the design and implementation of a corrugated box through a supply chain from design to potential post-consumer reuse. From this study, we found opportunities to improve the environmental design of the corrugated container through four ex ante design stages, and two ex post facto supply chain stages. Further, research can evaluate and refine this model via a 'live supply chain' for use in guiding corrugated box material selection design and reuse/recycling. Integration of the design criterion for a unit load in the supply chain creates opportunity to observe the packaging system holistically. Waste in the manufacturing process and CO2 emissions are traced along the material flow until the end of its useful life to provide an overall picture of the packaging system.

- Consumer packaging made from carton board is subjected to a variety of loads as it moves through the value chain. Packaging designers need tools for predicting the strength of packages under these loading conditions. For evenly distributed loads, there are methods for measuring and estimating compression resistance that can provide useful guidance. For loads concentrated to a small area, little work has been published. The aim of this preliminary study is to aid the development of a future test method for point loads by investigating how the size of the load application site influences the mechanical behaviour of the package. Rigid spheres of a range of sizes were used to compress packages. Small spheres gave rise primary damage in the form of a vertical yield line and secondary damage in the form of a parabolic yield line. Larger spheres produced a series of parabolic yield lines of increasing size. No vertical yield line appeared for the larger spheres. The larger spheres showed a stiffness transition at a displacement that could be estimated by considering the geometry of the test.

Elucidating the Indirect Contributions of Packaging to Sustainable Development : A Terminology of Packaging Functions and Features
- 2016

- Packaging has great potential to contribute to sustainable development through its functions. Previous research has indicated a need for increased knowledge among consumers, suppliers, authorities and media of how packaging functions and features influence sustainable development. Previous research also shows the need for a common terminology of packaging functions and features in order to facilitate and improve communication and understanding in development and decision processes. This conceptual paper sets out to identify, collect, analyse and systemize packaging functions and features and evaluate them based on their indirect contributions to sustainable development. The systemized functions and features are expressed in generic terminology. Three clusters of packaging functions were identified from the literature: protect, facilitate handling and communicate. Nineteen packaging features were also identified. They were grouped under the three functions and elaborated based on their indirect contributions to the environmental, social and economic dimensions of sustainable development. Fourteen potential positive indirect effects were identified including decreased product waste, reduced risk for human health hazards, increased handling and transport efficiency. Decreased product waste was generated by 13 of the features and was thus the most frequently appearing. Reducing waste is thereby indicated to be a manifold matter, but also one of great potential. The proposed terminology can contribute to an increased understanding of how packaging can actually contribute to sustainable development. In a theoretical context, this paper attempts to complement earlier work in sustainable packaging development by its emphasis on the indirect contributions of packaging to sustainable development.

Tidskriftsartikel (refereegranskat)abstract
- A crippling analysis method has been utilized to estimate the compression strength paperboard boxes. Crippling analysis is typically utilized in the aerospace industry to predict the compressive failure strength of thin, slender structures with complex cross-sectional geometry. This type of analysis is investigated, because crippling is a simple, predictive method that can provide very good estimates of the compressive failure strength of thin, slender structures. This preliminary study investigates the possibility of applying crippling analysis to estimate paperboard box compression strength by comparing experimental and theoretical results for box compression tests of milk and cigarette boxes in various loading scenarios and with various materials. This preliminary study shows that the crippling method provides results which are almost as accurate as pre-existing methods, although significant work remains to verify the validity and applicability of the crippling approach for paper-based boxes.

Tidskriftsartikel (refereegranskat)abstract
- A moisture-dependent and temperature-dependent constitutive model for paper materials was proposed and implemented into a finite element model of the paper hydroforming process. Experimental hydroforming was conducted at temperatures of 23°C and 110 °C and moisture contents of 6.9 and 10.6 (respectively corresponding to 50 and 80% relative humidity). The proposed model, which also included the effects of drying, captured the extent of forming of all experimental results within reasonable accuracy. For the moisture content and temperature conditions in this study, the phenomenon of drying was found to be the reason why the application of temperature had a much greater effect on the degree of forming than hydroforming at various moisture contents. A simulation-based parametric study was conducted in order to identify the importance of various process and material parameters. This parametric study confirmed many previous empirical findings and was capable of quantifying the extent to which these process and material parameters affect the three-dimensional formability of paper. The coefficient of friction was identified as one of the most important factors when determining the extent of forming.

- Medication packaging is essential to provide patients with guidance and correct use of their medicines for effective treatment. This research aims to increase knowledge about the medication packaging innovation process and its uptake towards patient‐centered packaging design. The study applied a qualitative research approach based on data from 25 in‐depth interviews with stakeholders involved in medication packaging design. The empirical data analysis revealed four themes that can improve and advance user‐centered packaging design: medication packaging innovation process, medication packaging functions and features, medication packaging design constraints, and patient‐centered medication packaging design. The findings suggest that medication packaging design is strongly affected by an emphasis on protective and safety packaging functions rather than on patients' needs. Packaging innovation usually is constrained by rigid incremental development processes, where compliance with regulations, extensive documentation, avoidance of manufacturing complexity, and considerations on cost prevail. These findings are discussed in relation to the three most evident trade‐offs for patient‐centered design: protection versus openability, utility versus cost, and complexity of manufacturability versus complexity of use. This research contributes with valuable input and additional evidence about the necessary shift to a user‐centered approach in a field that has not been design driven. This input complements previous research and provides an opportunity for industry decision makers and policy makers to lead patient‐centered packaging design that can benefit patients and relieve overloaded health care systems.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to provide insight into how companies work during packaging development to reduce negative environmental impact along supply chains, and to compare their practical approaches with the theoretical concepts presented in the literature. The research approach is explorative and based on nine cases in the food and manufacturing industries in Sweden. Data were collected from the managerial perspectives of the packaging manager, the logistics manager and the environmental manager. The findings indicate that companies commonly apply a variety of green packaging approaches with a focus on approaches with clear economic benefits. Moreover, companies seem to lack guidance on how to handle trade-offs and are unable to fully utilize the theoretical environmental benefits of green packaging approaches because of internal and external barriers. The paper presents five propositions regarding to what extent the theoretical green packaging concepts are applied in practice. To address the gap between theory and practice companies should: develop packaging solutions that contribute to a reduction of environmental impact from the consumer phase (for example through improved apportionment, user-friendly and informative packaging); use local packaging adaptation as a strategy to address geographically varying transport, handling and waste management conditions; replace brand recognition through packaging size and shape with graphic design, high-quality materials and printing. The results confirm that internal and external collaborations are important requirements for successful green packaging development. Copyright (c) 2015 John Wiley & Sons, Ltd.

Simulation and experimental verification of a drop test and compression test of a gable top package

Tidskriftsartikel (refereegranskat)abstract
- A finite element framework has been proposed that can be used to simulate both empty paperboard packages and package filled with plastic granulates. A gable top package was made of a commercial paperboard, and material properties needed in the material model were determined. Two simulations were performed, a drop test and a compression test. By comparison between experimental and numerical results, the deformation mechanisms at impact could be identified and correlated to material properties. When the package was filled with granulates, different mechanisms was activated compared with an empty package. The granulates contribute to bulging of the panels, such that the edges became more load bearing compared with the panels. When the edges carried the loads, the importance of the out-of-plane properties also increased, and local failure initiation related to delamination was observed. Comparison between experimental and numerical impact forces shows that there are still important things to consider in the model generation, eg, variation of properties within the package, which originate both from material property variations, and the loading history, eg, during manufacturing and handling.

Efficient and accurate simulation of the packaging forming process

Tidskriftsartikel (refereegranskat)abstract
- To allow for large-scale forming applications, such as converting paperboard into package containers, efficient and reliable numerical tools are needed. In finite element simulations of thin structures, elements including structural features are required to reduce the computational cost. Solid-shell elements based on reduced integration with hourglass stabilization is an attractive choice. One advantage of this choice is the natural inclusion of the thickness, not present in standard degenerated shells, which is especially important for many problems involving contact. Furthermore, no restrictions are imposed on the constitutive models since the solid-shell element does not require the plane stress condition to be enforced. In this work, a recently proposed efficient solid-shell element is implemented together with a state-of-the-art continuum model for paperboard. This approach is validated by comparing the obtained numerical results with experimental results for paperboard as well as with those found by using 3D continuum elements. To show the potential of this approach, a large-scale forming simulation of paperboard is used as a proof of concept.

- Packaging and the role it plays in supply chain efficiency are overlooked in most design and development research. An opportunity exists to meet the needs of supply chains to increase efficiency. This research presents three propositions on how to reduce the gap between supply chain needs and satisfaction in interaction with the product and packaging system. It also proposes a supply chain focused packaging design and development method to better satisfy supply chain needs placed on packaging. An extensive literature review was conducted, and a Tetra Pak derived case study was developed. The propositions were formulated and became the basis for improving Tetra Pak's existing packaging design and development method by better integrating supply chain needs. This was accomplished by using an expanded operational life cycle perspective that includes the entire supply chain. The resulting supply chain focused packaging design, and development method enables improved supply chain efficiency while considering the product, the processes and cost.

Packaging's Role in Minimizing Food Loss and Waste Across the Supply Chain
- 2015

Tidskriftsartikel (refereegranskat)abstract
- This paper presents the results of Australian research that explored the role of packaging in minimizing food waste in the supply chain. The economic, social and environmental costs of food waste have been well documented elsewhere. This research contributes to the debate by identifying opportunities to reduce or recover food loss and waste through improved packaging. In the fresh produce sector, e.g. waste can be reduced through the use of packaging that improves product protection, ventilation and temperature control. Other opportunities include improved design of distribution packaging to reduce damage in transport and handling; design of primary packaging to reduce waste in the home, e.g. through appropriate portion sizes and by reducing confusion over date labels; and the use of retail-ready packaging that minimizes handling and improves stock rotation in stores. An important conclusion of the study is that packaging can have a significant impact on reducing food waste in the food supply chain; and in some cases, a focus on reducing food waste will require more rather than less packaging. Packaging developers must therefore consider the product and its packaging as a complete system to optimize sustainability. Copyright (c) 2015 John Wiley & Sons, Ltd.

- Packaging has a fundamental role in ensuring safe delivery of goods throughout supply chains to the end consumer in good condition. It also has great potential to contribute to sustainable development. This paper explores and provides insights on Swedish consumer perceptions and knowledge of environmental aspects of food packaging and elaborates on how these can contribute to or counteract environmentally sustainable development. A study based on a consumer survey carried out in Sweden is presented. A review of recent packaging research emphasizes the protective function of packaging as its most important contribution to the environmental dimension of sustainable development. Contrary to this, consumers almost exclusively refer to the packaging material when it comes to their perceptions of the environmental impact of packaging. Paper-based packaging is strongly understood by the surveyed consumers to be environmentally advantageous, whereas plastic and metal are not. This study further indicates that a majority of the Swedish consumers surveyed are aware of their shortcomings in judging the environmental status of food packaging, indicating a need for guidance; otherwise, consumer choices can unintendedly counteract environmentally sustainable intentions

Data Mining with Clustering Algorithms to Reduce Packaging Costs : A Case Study
- 2017
-
Ingår i: Packaging Technology and Science. - : Wiley. - 0894-3214. ; 30:5, s. 173-193
-
Tidskriftsartikel (refereegranskat)abstract
- Reducing package-related cost is essential for various companies and institutions. Different packages are usually designed separately for each and every product, which results in less cost-effective packaging systems. In this study, a data mining model with three clustering algorithms was developed to modularize a packaging system by reducing the variety of packaging sizes. The three algorithms were k-means clustering, agglomerative hierarchical clustering and self-organizing feature map. The package models with similar shapes and sizes were clustered automatically and replaced by one package model with a size that suited them all. The study also analysed the financial effects including the purchasing and inventory costs of the package material and the transportation cost of the packaged products. The case study was carried out at Ericsson to select the best clustering algorithm of the three and to test the effectiveness and applicability of the proposed model. The results show that the packaging system modularized by the agglomerative hierarchical clustering algorithm is more cost-effective in this case compared with the ones modularized by the other two clustering algorithms and with the one without modularization.
