  • Detection and identification of disturbances by spectral analysis of
           structure-borne noise during the production of a sealing seam

    • Authors: Felix Kruppa et al.
      Abstract: When sealing, disturbances or errors can occur that impair the quality of the sealing seam and, in the worst case, lead to leaks. It is therefore important to identify and eliminate defective packages during production and to minimize the elimination by readjusting machine parameters. The aim of this article is the clear identification of seam quality problems on a vertical forming, filling and sealing machine SVE2520 by evaluating process parameters during the manufacturing process. For this purpose, the structure-borne noise is measured for each seal in order to identify not-usual curves. These not-usual curves are related to different disturbances or errors. By combining sensors technology, data analysis and step-by-step clustering, most damage images can be clearly differentiated from one another and that only by using the structure-borne noise.

  • Influence of Pinholes on Water Vapor and Oxygen Permeation of Packaging
           Foil and Films

    • Authors: Petri Johansson et al.
      Abstract: Controlling of moisture and oxygen permeation through the packaging material is essential in most packaging applications. With multilayer structures of different barrier materials, there is possibility to create desired barrier properties to the package. The challenge is to plan appropriate barrier level, e.g. WVTR and OTR, theoretically to the package before producing the package. Furthermore, in specific packages there is a need to control the permeation e.g. respiration in vegetable packages. Typically foils and polymer films have high barrier properties, therefore, permeation can be controlled by producing artificial pinholes in these kinds of packages.Influence of artificial pinholes in aluminium foils and plastic films on water vapour and oxygen permeation was determined in this study. Results show clear correlation between the size and number of pinholes and gas permeation. Water vapour and oxygen permeation increase significantly when there are pinholes through the structure. It was observed that the greater the RH difference between inside and outside the sample in WVTR measurement, the greater the permeation was through the pinholes. Additionally, it was found that the effect of pinholes on the oxygen permeation on aluminium foil can almost be eliminated by using polyethylene coating on top of aluminium foil.

  • Functional inks and indicators for Smart Tag based intelligent packaging
           applications

    • Authors: Liisa Hakola et al.
      Abstract: Smart Tags are functional, information transmitting elements that combine 2D barcodes and environmental sensing into a cost effective tag that can be attached to e.g. product packages, where additional elements should not increase the product costs significantly. Important feature of these Smart Tags is that they can be attached to products in very high-speed production lines, which makes them suitable to fast moving consumer goods. Because the Smart Tags are sensitive to environmental conditions, they are dynamic, but they also enable context aware services as each of them can be unique. The enabling technologies behind these Smart Tags are i) 2D barcodes and ii) functional inks, such as thermochromic and photochromic inks, and iii) printed visual indicators. In this paper, different ink and indicator technologies are used to build Smart Tags. Both commercial inks and developmental grades are in focus. Furthermore, it is evaluated if these tags can be detected by mobile phone reader.

  • Experimental verification on the effectiveness of random vibration testing
           with controlling acceleration and velocity kurtosis

    • Authors: Daichi Nakai et al.
      Abstract: Random vibration tests for packages are conducted to confirm the safety of these packages during shipping. In our previous study, a method of generating the random vibration controlling the power spectral density and kurtosis of acceleration and the kurtosis of velocity was proposed. The aim of the present study is to verify the effectiveness of the proposed method. Three vibrations were generated in this study and compared with the real vibration, which replicates the truck bed. In the first case, control of the acceleration and velocity kurtosis was neglected. In the second case, the vibration controlling the acceleration kurtosis was considered. The third case corresponded to the vibration controlling both the acceleration and velocity kurtosis generated by the proposed method. In the present study, an aluminum plate simulating the product was fixed to a table for evaluating the vibrations. The natural frequency of the plate was varied by varying the mass of the weight placed on the plate. The relative displacement of the plate was calculated from the difference between the readings of two laser displacement meters. The vibrations were evaluated via the root mean square, kurtosis, and skewness of the relative displacements of the plate. Kurtosis and skewness of the relative displacement of the proposed method were similar to those of the real vibration. However, the kurtosis and skewness of the other generated vibrations were far from those of the real vibration. Results provided experimental verification that the kurtosis of velocity is an important factor for random vibration tests.

  • Reconfigurable Cushion Design for E-Commerce Packaging using Kirigami
           Concept

    • Authors: Euihark Lee et al.
      Abstract: In packaging, cushion barriers are needed to provide content protection in a disposable form. However, conventional cushioning materials and designs typically require a large volume, which decreases shipping and storage efficiency and increases environmental impact. Especially in e-commerce, where “shipping and handling” occur at an exceedingly rapid pace in large-scale operations, many packages suffer from being over or under packed through the fulfilment process. To solve this issue, this paper presents deployable kirigami-based cushion designs that can be collapsed or deployed depending on the distribution situation. Kirigami is a variation of origami that involves both cutting and folding of paper. The advantage of this design is that the kirigami cushion can be applied on the outside of a shipping container, instead of inside. Therefore, the shipping container itself can be more compact and the cushioning can be accessed and deployed when it is needed. The deployable kirigami cushion design was evaluated using compression and vertical impact tests, and the testing results are presented.

  • Optimization in the Application of Varnishes Barrier on Cartonboard
           Packaging

    • Authors: Andre Ramalheiro de Andrade et al.
      Abstract: In this work adjustments in the rotogravure printing process are proposed to the varnish water vapor transmission rate (WVTR) aiming to obtain results smaller than 20g/m²/24h. One case study was used for the propositions for improvements, where focused on varnish application process in a gravure printer for an eight-printing unit cartonboard packaging, maximum printing speed of 175 m/min and a 285 g/m² weight cartonboard. The possible variables that influenced the WVTR result were selected from the technical expertise of the people involved in the project, the analysis in the printing process with the application of directed trials using experimental designs (DOE). After realizing forty four trials in a printing machine, were identifying and defined thirteen process adjustment parameters to the best analysis. The project was developed for a cartonboard packaging with a varnish water vapor transmission rate (WVTR) with capacity to pack 500g of a product. The obtained results allowed the proposition for improvements in the studied printing process, used by the print shop to reduce significantly the WVTR used. The records of the results are an average of 25.98g/m²/24h, before the study, and after implementation of improvements there was a reduction to 18.16g/m²/24h in the average of the results, 1.84 g/m²/24h below the target. The WVTR standard deviation was from 8.95 g/m²/24h to 2.22 g/m²/24h, thus presented better process stability. There are large number of solvents and resins, which can be applied in rotogravure machines, and each has its specificities. Based on all the expertise acquired from the study, it is possible to propose a line of work to find precise adjustments in the varnish application. Therefore this study addresses an important approach to the future of sustainable packaging, which contains little information in technical literature.

  • Listening to Current Practice: Patient Involvement in the Pharmaceutical
           Packaging Design Process

    • Authors: Giana Carli Lorenzini et al.
      Abstract: Multiple functional challenges in the use of pharmaceutical packaging reveal a great need of packaging to be designed inclusively. This study investigates patient involvement in the pharmaceutical packaging design process by analysing interview data from representatives of the pharmaceutical and packaging industry. Four main themes related to patient involvement were uncovered: patient expertise levels, patient involvement modes, factors encouraging patient involvement, and factors discouraging patient involvement. Passive patient involvement modes were found to be dominant due to regulations and a traditional perspective regarding physical testing. However, active patient involvement modes were identified, motivated by empathy and understanding of the lives of patients. The pharmaceutical packaging design process is complex and involves multiple stakeholders. The research findings can inspire more industry practitioners and policymakers to design pharmaceutical packaging that is inclusive and with consideration of a broader spectrum of patients’ needs.

  • Evaluation of stretch film behavior during long-term storage under
           different atmospheric conditions

    • Authors: Kyle Dunno et al.
      Abstract: This study examined the post-application behavior of two 20.3 micron machine stretch films, one categorized as high-performance and one as general-performance, for thirty days while stored at either 23°C or 38°C. For each film type, the stretch film was applied to a simulated unit load to produce neutral and positive applied total stretch scenarios. The relaxation curves developed from each test indicate the relaxation rate of the films varied based on the storage condition. Observed was an average of 41% containment loss for both high-performance and general-purpose films when the simulated loads were stored at 38°C. For simulated loads stored at 23°C, the reported average containment loss for both films was 26%. The application of the film, either neutral or positive, did not greatly affect the percent loss in containment for the film. Additionally, results showed the greatest amount of containment force loss occurred during the initial 2 h of storage for all 23°C treated samples and 38°C general-purpose treated samples, while 38°C high-performance films continued to relax for 7 days until no difference was observed.

  • Life Cycle Assessment of Packaging Systems for Enteral Nutrition Products:
           Multilayer Pouch and High-Density Polyethylene Bottle

    • Authors: Martina Krueger et al.
      Abstract: Environmental performance of alternative packaging options for a given product application increasingly comes into awareness, both at the end consumer level as well as in the field of business-to-business communication. The purpose of the study presented here is to examine the environmental performance of a multilayer pouch for packing of enteral nutrition products. To achieve this, a life cycle assessment has been conducted. As an attributional full cradle-to-grave life cycle assessment it compares environmental impacts of a comparable lighter multilayer pouch vs. two different comparable heavier high-density polyethylene bottles (covering the weight range of high-density polyethylene bottles on global markets for enteral nutrition products) in two different sizes (500 mL and 1000 mL). All life cycle steps are taken into account: from the extraction and production of packaging raw materials over converting and filling processes to all transports as well as recycling and/or final waste disposal (landfill and/or incineration) of the packaging materials after their use. The functional unit of this study is the packaging required to deliver 1000 liters enteral nutrition product to the customer at the hospital. The study aims to cover various markets: Europe, Latin America and Australia. To depict the different markets, a cluster approach was chosen. The clusters are based on two criteria: geography of target markets, which determines the distribution (truck and/or ship) and transportation distances; as well as the end-of-life final waste treatment routes – either landfill or incineration. An essential difference between the two product types (multilayer pouch and high-density polyethylene bottle) is the mechanical recycling option for the high-density polyethylene bottle, which is currently not applicable for the multilayer pouch at a commercialized level. The results of the study show that the multilayer pouch packaging system is favorable from an environmental point of view versus alternative high-density polyethylene bottle systems in the field of enteral nutrition products. The ecologic advantage of the multilayer pouch system is based on the reduced initial material use compared to high-density polyethylene bottles requiring a higher polymer amount in production. This applies to both sizes and all geographic clusters taking into account the mechanical recyclability of the high-density polyethylene bottles.

  • A Dynamic Programming Approach to Determine Optimum Modularity Level in
           Industrial Packaging

    • Authors: Marshal Louie et al.
      Abstract: Modular packaging facilitate customization for accommodating variable product sizes in a product family. When determining package sizes for product variability, packaging engineers does not find difficulty to determine package dimension for less product variety whereas if the product variety is more, then determining the dimension of modular package involves complex decision-making and time-consuming process to find the optimal solution. This in turn directly impacts the overall lead time of the supply chain. Thus, in this paper a dynamic programming is developed to determine the quantity and dimension of modular packages for every demand of assorted products sizes. The program helps in finding the optimum modularity level of the modular packaging by identifying the midpoint between reduced space wastage and minimum production quantity. Four different case studies are employed in this research to illustrate how the levels of modularity has the effect on reducing the source material wastage by volume. From the results of the case studies, the percentage improved in the container space utilization is represented.

  • Study of UV Degradation on Plastic (PET) Aerosols

    • Authors: Rodney L. Prater et al.
      Abstract: The present study was aimed to explore the impact of UV radiation, from ‘real world’ environmental exposure, on the degradation of plastic PET aerosol containers. Additionally, the intent was to correlate the ‘real world’ environmental exposure to artificial sunlight, using a Xenon-Arc lamp, to develop a simulated test. The standardized methodology could then be used to evaluate the integrity of the plastic aerosol container and product, without the complexity of using ‘real world’ exposure. Through this study, a lab method was developed and validated that would simulate the effect of UV radiation using the Xenon-Arc. Moreover, a correlation was made for conditions inside the Xenon-Arc chamber that were conducive to testing a plastic pressurized container.

  • Influence of Fiberboard Container Design on Compression Bulge Displacement

    • Authors: Koushik Saha et al.
      Abstract: Bulge effect is the out-of-plane displacement of a panel of a corrugated fiberboard box from its original position. This bulge effect often is the result of excessive weight being placed on a box that rests at the bottom of a palletized load. Panels that are out-of-plane reduce the stacking strength of the box and can result in damage to products inside the containers. This study was designed to find the influence of fiberboard container design on its bulging performance when under compression. The objective of the study was to determine if change in height of a regular slotted container will affect the bulging performance in relation to different environmental conditions. For this study, a three heights were selected based on the market study of the natural produce sector and testing was conducted in accordance to American Society for Testing and Materials (ASTM) standards. All the samples were conditioned in accordance to ASTM and Technical Association of the Pulp and Paper Industry (TAPPI) standards. Data analysis for the three box heights suggests that compression bulge displacement may be affected in some scenarios.

  • Evaluation of a Bulge Reduction Technology for Corrugated Fiberboard
           Containers Under Static Compression

    • Authors: Daan Peleman et al.
      Abstract: This research examines the effect of top-to-bottom static compression load on the bulge of RSC containers. The study compares a control regular slotted container (RSC) constructed with corrugated fiberboard to tape-reinforced designs. The bulge reduction, achieved using various tape placements and conditioning environments, were measured. Currently, no research on the effect of reinforcement tape towards reduction in the out-of-plane displacement (bulging) of the corrugated fiberboard panels has been undertaken. Samples related to four different container designs, varying by presence, quantity and the position of the reinforcement tape on the vertical panels, were tested and analyzed. The study involved the use of a prototype cutting table, environmental conditioning chambers, a compression testing system and a patented container bulge measuring fixture. The statistical analysis of the observations confirms that the reinforcement tape significantly reduces the out-of-plane displacement of the container side panels under ambient environmental conditions (23 ± 1 °C, 50 ± 2% relative humidity). In tropical and refrigerated conditions (40 ± 2 °C, 90 ± 5% relative humidity and 5 ± 2 °C, 85 ± 5% relative humidity) it was observed that the reinforcement tape has potential in reducing bulge. The findings of this study should be valuable to packaging engineers towards the potential reduction of material usage while improving the stacking strength and rigidity of an optimized corrugated fiberboard containers.

  • Obtaining mechanical shock fragility statistics for simple stochastic
           cushioning design.

    • Authors: Shogo Horiguchi et al.
      Abstract: Proper cushioning to prevent product damage and over-packaging must consider the mechanical-shock fragility of the product. Furthermore, improved cushioning design can be achieved by performing stochastic cushioning design using mechanical-shock fragility statistics and transport hazard statistics. However, many samples are required to obtain mechanical-shock fragility statistics from standard testing comprising critical velocity change tests and critical-acceleration tests (the “conventional method”). In many cases, the required number of samples cannot be prepared. Thus, this research is designed to develop testing methods requiring half the number of samples of the conventional method. Thus far, "test method with one sample" has been developed by improving the standard testing method required two samples. Hence, we propose a new statistical method (the “proposed method”) that obtains statistics by multi-sample testing using a test method with one sample. The proposed method is one in which the shock of a single velocity change (the “test velocity change”) is given by increasing the acceleration in a step-wise fashion, and the results indicate the failure rate at the test velocity change and provide the critical-acceleration statistics. In these experiments, the critical-acceleration statistics for a test velocity change larger than the critical velocity change were equivalent to those obtained from the conventional method. The accuracy of the failure rate at test velocity changes was clarified. Moreover, examples are provided showing the results when the proposed method is applied to simple stochastic cushioning design.

  • Improvement of durability and sliding properties of food packaging
           equipment by combined treatment of Diamond-like carbon coating and Fine
           particle bombarding

    • Authors: Kotono Mikamoto et al.
      Abstract: Recently, there is a demand for the development of an eco-friendly surface treatment technology that can replace PTFE coating and hard chrome plating, which are a common process for food packaging equipment. We intended to improve the sliding properties and wear resistance of food packaging equipment by the fine particle bombarding (FPB) process to a metal substrate and depositing diamond like carbon thin film under atmospheric pressure (AP-DLC). These treatments are eco-friendly and low-cost. The Stainless steel substrates treated by FPB showed better sliding properties than the mirror substrate. By FPB treatment, AP-DLC coating was successfully applied to steel substrates without peeling. Also, by coating AP-DLC on the FPB-treated substrate, the width of wear track after the sliding test was reduced by 20% compared to the mirror substrate, and the wear resistance was improved. These results indicate that the metal using the combined treatment of FPB and AP-DLC coating is a promising material for food packaging equipment.

  • Effects of period and temperature on quality and shelf-life of cucumber
           and garden-eggs packaged using cassava starch-zinc nanocomposite film

    • Authors: Adeshina Fadeyibi et al.
      Abstract: Nanocomposite film can be used to prolong the shelf-life of fruits and vegetables. This research was undertaken to investigate the effects of packaging period and temperature on the quality and self-lives of cucumber and garden-eggs packaged using cassava starch-zinc nanocomposite film. Hundred grams each of cucumber and garden-eggs were wrapped in a 200× 350 mm size nanocomposite film and low density polyethylene (LDPE) of 2.240± 1.076 × 10-10 gm-1Pa-1s-1 water vapor and 1.568± 0.084× 10-10 gm-1Pa-1s-1 oxygen gas permeability. The products were stored at 10−27oC temperatures and 0−9 day periods, and their quality attributes including β-carotene and ascorbic acid were determined. The results showed a high positive correlation for β-carotene and ascorbic acid contents of the cucumber and the garden eggs packaged in the nanocomposite film and the LDPE (p< 0.05). Also, the percentage increase in shelf-life of the packaged products in the cassava starch-zinc nanocomposite films was higher than those packaged in the LDPE materials. This indicates a small quality loss in the products packaged using the nanocomposite film compared with that packaged using the conventional LDPE. Hence, cassava starch-zinc nanocomposite film can be used to extend the shelf-life of the products.

  • Unpackaging aseptic presentation: A qualitative study into the contextual
           influences involving medical packaging design and use heuristics among
           perioperative personnel

    • Authors: Tony Trier et al.
      Abstract: Newly emerging mandates in the Medical Device Regulation in Europe and additions to ISO 11607 require medical device manufacturers characterize how package designs facilitate (or hinder) aseptic transfer by perioperative personnel.The present work utilized a semi-structured interview with clinicians on the topic of aseptic presentation. Methodological decisions related to the interviews and assessment of results were undergirded with affordance and situated learning theories to identify the components of a user experience. QDA Miner software was used post-hoc to code, quantify, and categorize the data into major and minor themes.The study identifies several components within the user’s experience that influenced aseptic transfer, including: context (e.g. staff availability), coworkers’ input, and variation in individuals' interpretation of acceptable practice related to the transfer of devices to the sterile field and appropriate handling of packaging.To comply with the changing regulatory landscape surrounding the safety of medical devices, the industry should employ human factors methodologies to better understand how sterile packages will be used by the clinician “aseptically”.

  • Development and Experimental Investigation of Modular Crates for
           Industrial Packaging Applications

    • Authors: Marshal Louie et al.
      Abstract: For the increased product varieties, engineered plywood crate production technique could not facilitate box size optimization. This paper investigates the implementation of modularity function onto the plywood crate to resize the pack cube volume on customer requirement and to reduce space wastage inside the box. This is achieved by using a new joint technique called “Flat- Post Tongue Joint”. The full-sized experimental work is carried out comprising Flexural test analysis on Flat-Post Tongue joint, Tensile test analysis on tongue joint and Box Compression Test analysis on the two developed models of modular crates namely Modifiable Reinforced Plywood Crate (MRPC) and Modifiable Plywood Crate (MPC). The test results exhibited an improved flexural strength and box compression strength in comparison to the conventional plywood crates. The findings of the research work indicates that the modular plywood crate is a performance efficient method to reduce space wastage and source material by weight and volume when accommodating variable product sizes in a product family.

  • Moisture Sorption Behavior and Shelf Life Prediction of Teff Seed and
           Flour

    • Authors: Baba Abdissa et al.
      Abstract: Moisture sorption isotherms of Teff seed and its flour were determined over the range of relative humidity (11–92%) using a gravimetric technique at constant temperature (27°C). The results obtained showed that the moisture sorption isotherm of both is almost similar and sigmoid with increasing equilibrium water content at the constant temperature. The curves start raising high above 64% RH indicating the products deteriorates faster above 64% RH. Hence the moisture content equilibrating to 64% RH was taken as critical for both Teff seed and flour variants. The sorption isotherm fits the GAB equation as per GAB generalized equation for sorption phenomena (Bioprocess Technol, 2008) with R2>0.96. A nonlinear regression analysis method was used to evaluate the constants of sorption equation and the values of GAB constants of which Mo=7.5075, C=14.3886, K=0.7051 for Teff seed and Mo=6.9656, C=10.4012, K=0.7255 for Teff flour respectively. The shelf life of the product was predicted using, Mpack software developed in-house to "prediction of the shelf life of moisture sensitive products" using GAB parameters and packaging Schedule.

  • Research on Color Matching Model for Color QR Code

    • Authors: FEI YOU Dr. et al.
      Abstract: Objective To provide a faster and more effective way for consumers to obtain the additional information of product, the color quick response (QR) code is printed on product packaging. To improve decoding accuracy of color QR codes. This paper constructs a color matching model with good performance, which restrains aliasing between two color encoding modules of color QR code. Methods By comparing and analyzing the character of several typical color spaces, the HSV color space was chosen for its favorable attributes. Based on the enlarging capacity principle of color QR code and the maximum rule of relative Euclidean distance, 2n-1 base-color points are set in the HSV space, and 2n-1 pair-color points are calculated by using color distance equation, resulting in a formula capable of encoding 2n colors. Results Results show that the color gamut of QR code pictures generated using our proposed model is wider than that generated using another color matching model. Color aliasing between two encoding modules was greatly restrained. Conclusion The proposed color matching model offers good performance, based upon wider color gamut and reduced aliasing, for generating color QR codes in the HSV color space. Consumers can scan the printed color QR code on product packaging with their electronic devices to obtain more exhaustive information of product effectively.
