A participatory process involving relevant food‐packaging experts and end users was applied to define the relevant criteria for each pillar. Each criterion was translated into a question for users, and the answers are converted into a score between 0 (worst option) and 1 (best option) per pillar. For the Materials pillar, two scores were computed from a streamlined calculation of resource (CEENE) and carbon footprints (IPCC) while for the Functionality and Post‐Usage pillars, scores were computed from Yes/No answers provided by the users. A fourth pillar considers the potential risk of long‐term environmental pollution. Then, the packaging options for the same food are ranked according to the Borda voting rule, considering the individual rankings obtained for the various pillars. The proposed methodology was applied to three commercial (milk and sugar) and non‐commercial (strawberry) packaging case studies. The obtained ranking is discussed with respect to current knowledge in the field. The provided methodology is easy to understand, science based, and combines quantitative and qualitative assessments. The developed tool could be handled by non‐experts in environmental sciences such as food manufacturers, packaging converters and policy makers. The resulting indicators provide answers to user concerns regarding the environmental impacts of food packaging and guide their choice of the most sustainable option. The proposed scoring method considers the functionality of the packaging with respect to preserving food and reducing food waste, which is rarely considered in packaging environmental assessments.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"352 1","pages":"439 - 463"},"PeriodicalIF":2.6,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80045071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research on its raw material, that is, corrugated fibreboard, has always been an important topic in the packaging field. However, the research objects nearly focus on the corrugated fibreboard of traditional corrugated medium. The innovative research on the structure of corrugated fibreboard is also still rare. Since the pandemic COVID‐19 in 2020, the international corrugated packaging industry has faced new dilemma. The development of new corrugated boxes and fibreboard is the way to break the situation in innovation and transformation. This study aims to design a new fibreboard with laminated structure medium for obtaining a new type of corrugated fibreboard for packaging with better cushioning and anti‐vibration performance than traditional corrugated fibreboard. The verification experiments show that the new fibreboard has better recovery and structural stability due to its unique three‐layer structure. The static and dynamic cushioning performance and anti‐vibration performance of the proposed fibreboard have been greatly improved compared with those of the traditional one.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"17 1","pages":"411 - 423"},"PeriodicalIF":2.6,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82922024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD) and RGB colour analysis showed the homogenous distribution of GSE in the starch matrix. The presence of GSE reduces the thermal stability, k1 value, solubility, swelling values and the %E and increases the tensile strength (TS), revealing its plasticizing potential action in the presence of isomalt. The influence of pH on the colours of the film containing GSE and its indicator activity were evaluated. The results showed that the film produced operates in a wide pH range, being an excellent candidate as an indicator for monitoring fish freshness.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"7 3 1","pages":"425 - 437"},"PeriodicalIF":2.6,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90250622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A. Venditti","doi":"10.1002/pts.2717","DOIUrl":"https://doi.org/10.1002/pts.2717","url":null,"abstract":"Significant efforts have been made over the past decade to facilitate the recognition of environmentally friendly packaging and promote sustainability. Yet, consumers remain confused by the excess of labels and claims used to communicate sustainability. In our previous work, we modified the appearance of recycled fibre‐based packaging by incorporating visible particles of fibre‐based waste. This strategy enabled consumers to better identify packages with a high recyclability level, enhancing their environmental perception towards sustainable products. However, the incorporation of such large waste particles proved to be detrimental to the mechanical properties of the paperboards. In this study, we further investigate the influence of the physicochemical properties of the added fibre‐based waste on packaging performance. Using a similar strategy to enhance the environmental perception, we herein studied the effect of mixed office waste (MOW), old magazines (OMG), and polylactic acid (PLA) paper cups. The presence of hydrophobic and difficult‐to‐process and difficult‐to‐disperse waste, such as the PLA paper cups, significantly altered the mechanical performance of the paperboards, whereas more hydrophilic and easy‐to‐disintegrate waste (MOW and OMG) had a lesser effect regardless of the size of the particles. Strength agents such as cationic starch (CS) and cellulose microfibrils (CMFs) successfully restored the properties of the paperboards containing MOW and OMG but were less effective for PLA paper cups. A multi‐ply strategy overcame the limitations of CS and CMFs using the redesigned paperboard as an outer ply for aesthetic purposes and a 100% recycled inner ply for restoring strength.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"51 1","pages":"363 - 377"},"PeriodicalIF":2.6,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74604698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Estimating minimum required dwell time for the heat sealing of talc containing polypropylene/low‐density polyethylene packaging films","authors":"I. Ilhan, M. van Drongelen, Roland ten Klooster, I. Gibson","doi":"10.1002/pts.2716","DOIUrl":"https://doi.org/10.1002/pts.2716","url":null,"abstract":"Dwell time is one of the main parameters influencing heat seal quality and process efficiency in flexible packaging. In this study, the rheological behaviour of polypropylene (PP)/low‐density polyethylene (PE‐LD)‐based compound films containing different ratios of talc was examined. The minimum dwell time required to supply a sufficient sealing was estimated based on heat conduction time and reptation time. Reptation is a rheological concept used to described the behaviour of a polymer melt, and the reptation time is the time required for a molecule to escape from its surrounded entangled structure. The results showed that increased levels of talc are associated with elevated complex viscosities, storage and loss modulus as well as an increased seal strength. The estimated minimum required dwell time at the seal initiation temperature (SIT) dropped sharply with the initial introduction of 10 wt% talc. However, increasing the talc ratio to 30 wt% did not create any major change in the estimated time value. Also, observed T‐peel strength values for 0.1 and 0.5 s dwell time at SIT confirmed the predicted minimum required dwell time values. On the other hand, when the seal temperature is increased to the higher end of the operation window, time estimations did not match with the observed seal strengths. Here, the melting already starts and the molecules diffuse up to a certain distance before the interface temperature reaches the desired level. Recalculation of the average diffusion distance by including this pre‐melting situation can present a better approach for the temperatures above SIT. When the molecules diffused around halfway along the sealant thickness observed, seal strengths reached a sufficient level (2.5 N/25 mm) for both SIT and the highest end of the operation window. In conclusion, it has been revealed that knowing the reptation time and the required time for the heat conduction during the sealing process can help to predict the minimum required dwell time to achieve quality sealing, especially at low sealing temperatures. Additional surface characterizations also helped to elaborate on the influence of changing insoluble filler ratio on the seal initiation properties. It has been showed that the added talc increases the surface free energy and supplies easier wetting at the seal interface. Therefore, adding talc or a similar insoluble filler can help to make the heat sealing process more efficient.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"98 1","pages":"349 - 361"},"PeriodicalIF":2.6,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80953028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Du Frane","doi":"10.1002/pts.2715","DOIUrl":"https://doi.org/10.1002/pts.2715","url":null,"abstract":"Commercial steel drums underpin the global economy, playing a pivotal role in the storage and transportation of critical materials. Transported and stored materials, such as food, chemical and nuclear waste, can be sensitive to ambient conditions, particularly moisture that can enhance negative effects such as corrosion and material degradation. Although international standards and regulations are in place for the qualification of steel drums, there are no current testing requirements, established limits or boundaries for the permeation of moisture into the drums during transportation or storage. This work aims to provide insights into the moisture ingress over time into properly sealed steel drums and provides estimated moisture ingress rates over time through extrapolation. Water vapour transmission rate (WVTR) measurements through the gasket material at 10–40°C were 0.11–2.1 g/m2/day resulting in a permeation activation energy of 30.2 kJ/mol. Water sorption measurements and Karl Fischer titration (KFT) on ethylene propylene diene monomer (EPDM) gasket material revealed a decrease in equilibrium moisture saturation with increasing temperature. KFT measurements also revealed the presence of moisture within the adhesive and drum wall after exposure to ambient conditions. KFT and Fourier transform infrared spectroscopy (FTIR) show that moisture will desorb from the EPDM and drum wall after exposure to desiccating conditions, although a minimal amount of moisture will remain present. When sealed to the manufacturer's recommendations, the steel drums are effective in minimizing moisture ingress. In sealed empty drums, moisture ingress rates for 19‐L drums were 0.4–1.5 mg/day at 25°C 15% relative humidity (RH) and increased to 7.1–8.8 mg/day at 40°C 90% RH, and moisture ingress rates for 210‐L drums were 2.5 and 3.5 mg/day at field deployment conditions of 15.5°C 51.5% RH and 23°C 40% RH, respectively.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"5 1","pages":"329 - 347"},"PeriodicalIF":2.6,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83717972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas permeabilities and permeability ratios were determined to measure the ability of the films to create an optimal atmosphere for red chili storage. PP film attained values close to the recommended MAP gas concentrations and maintained desirable chili quality parameters up to the 15th day. Biodegradable films did not achieve the recommended MAP gas concentrations, but high water vapor permeability prevented moisture loss and maintained firmness and overall quality. No discoloration was recorded in all MAP treatments, while biochemical parameters showed a decreasing trend, with measured levels significantly higher in MAP samples than unpacked samples. MAP for red chili was achieved using a packaging system, with similar gas permeabilities to PP film but with significantly higher water vapor permeability.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"12 1","pages":"379 - 388"},"PeriodicalIF":2.6,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89506824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this perspective, a comprehensive literature review, quantitative survey and qualitative individual in‐depth interviews were conducted as a research approach. Findings revealed that printing and packaging companies achieved SDGs (8, 9 and 12) mostly through their value proposition by supporting I4.0 components (cybersecurity, system integration, cloud computing, big data and Internet of things [IoT]). The business model affirms a digital‐oriented transition towards sustainability, fostering further development of I4.0. It also highlights the importance of redesigning traditional business models to embrace digitalization.
