Ripeness of fruits is one of the factors causing food losses in the supply chain. Food loss increases the environmental burden through additional production undertaken to compensate for the losses. Packaging decreases the losses and consequently, the environmental burden, but itself causes additional environmental burden. This study models the relationship between food loss reduction via packaging for ripened peaches and the environmental burden across their life cycle. The results reveal that the slope of the straight line approximating the relationship increases with transportation distance. Relationship between the slope and transportation distance shows that for transportation up to 100 km, packaging with lower environmental burden is sufficient while above 300 km, packaging that provides a high level of protection for peaches—with the consequent reduction in food loss contributing to the reduction of the environmental burden—is appropriate. We propose packaging with superior environmental‐friendly qualities, based on the transportation distance, for ripened peaches.

The potential of printing stiffeners of polylactic acid (PLA) by fused deposition modelling (FDM) on the panels of folding board boxes was investigated in view of reducing the board weight while maintaining the box resistance to vertical compression. Cyclic loading and unloading compression tests were performed under standard (50% relative humidity [RH]) and humid (85% RH) environmental conditions on boxes printed with different grid patterns. By only adding 7% in weight of PLA to the whole packaging, the performance was improved by 29% under standard conditions and 60% under humid conditions when the inner surface of box panels was printed with an orthogonal‐type grid. A comparison with a higher basis weight folding board suggested that 30% of raw materials could be saved. Results suggested that the grid mainly improved the stiffness of panels and could delay their buckling and thus the box collapse.

Paper‐based composite packages, which have been widely used for beverage in modern daily life, are featured of nutrition preservation and convenience. However, it is also causing environmental problems in urban areas because of the low recycling rate. The introduction of extended producer responsibility (EPR) is helpful to improving the recycling rate of beverage paper‐based composite packaging by extending the producer's environmental‐protecting responsibility for the product from its production to its end‐of‐life treatment. To find out the optimal strategy of applying the EPR system for beverage paper‐based composite packaging, this paper is conducted based on the basic framework of the EPR system, combined with the specific requirements of the EPR System Implementation Plan promulgated by China and the Implementation Plan of the EPR System for Beverage Paper‐Based Composite Packaging. An evaluation index system for beverage paper‐based composite packaging manufacturers is constructed to perform the EPR system, including three management‐level indicators, 10 standard‐level indicators and 42 programme‐level indicators. A comprehensive evaluation method is introduced to help the producers to fulfill the extended producer responsibility. Results suggest that beverage paper‐based composite packaging producers should first fulfill the responsibility in information disclosure, ecological design and use of recycled materials.

Inertial forces occur during the internal transport of a pallet with palletized goods. Therefore, transport packaging must guarantee that the goods resist these destructive forces. The effectiveness of a stretch hood as a transport package is researched in this study. Firstly, it is determined if a stretch hood can be applied accordingly without it being damaged by the forks of a forklift or an AGV when being picked up. Secondly, the resistance to horizontal inertial forces during the internal transport of a stretch hooded pallet load is researched. The performed study shows that many parameters influence the sleeving process. A well‐chosen stretch hood, applied with the correct machine settings, can guarantee both minimum requirements for internal transport.

An innovative process for packaging films sealing has been recently promoted: Heat is provided on the upper side of the polymer films. In this paper, sealing conditions are studied for two PET‐PE films. Melting temperature of the sealant layer material was determined by differential scanning calorimetry (DSC), through both conventional and successive self nucleation and annealing procedures. Interface temperature was measured during sealing, and a temperature model was fitted to compute the effective sealing time for each process parameter. Unconventional T‐peel tests were established with disk‐shaped seal samples. Strengths of the seals formed for different process parameters were measured. Results have shown that the melting temperature measured by DSC (108° C and 99° C for PE70 and PE120, respectively) is the seal initiation temperature of the materials. Results of T‐peel tests can be divided in two regions: A growth region where seal strength values increase, up to a threshold at which the seal strength is almost constant (20 N/10 mm). In the growth region, we propose a time–temperature relationship between seal strength, tool temperature, and effective sealing time in the form of an Arrhenius model CexpαTtn . The value of the time exponent n in the model is in agreement with what the chain diffusion theory predicted (n=0.5) .

Materials selection involves thousands of material types and evaluation parameters. Considering multisensory experience for packaging materials selection is an important trend but a difficult duty that involves uncertainty due to the subjectivity of humans. The main aim of this study is to establish a model to determine the consumer sensory experience of packaging materials as a function supporting packaging material selection development. When the consumer interacts before and after opening the packaging, vision and tactility are the foremost sensory feedback types, which are difficult to measure for fuzziness and uncertainty. Thus, given the consumer senses of vision and tactility, this paper addresses the relationship between sensory experience and packaging material properties. This is creatively formulated in three stages from the physical properties and the psycho‐physical to the affective levels. The proposed approach that combines fuzzy theory and three‐stage network data envelopment analysis (DEA) is used to rank 12 toning lotion bottle packaging materials. It is validated that this model allows a clear decision‐making basis for material selection in packaging design, and physiological signal tests provided key data to support material selection. Moreover, it realized the function of predicting physiological signal according to material properties by backpropagation neural network (BPNN).

Food packaging materials are often inevitably and imperceptibly damaged during the transportation, handling, and storage, and the disruption of their integrity poses a challenge to food preservation. Food packaging materials with self‐healing capability can automatically repair the damaged areas and reconstruct original properties to avoid degradation of food quality and loss of nutrients. Various self‐healing materials based on dynamic covalent bonds and/or dynamic non‐covalent interactions have been developed and applied in food packaging in the forms of films and coatings at laboratory scale, and more efforts are required for the commercialization of these novel smart packaging materials. This is the first review to summarize the recent progress in the preparation of self‐healing packaging materials through different mechanisms, compare the self‐healing efficiency under different conditions, and highlight the potential applications of self‐healing films and coatings with recoverable mechanical and barrier properties and other functionalities (e.g., antimicrobial and anti‐fogging capacities). Finally, the future opportunities and challenges of applying self‐healing materials in food packaging are described.

Fresh beef is a typically perishable food because of its high water and protein content; thus, it requires proper packaging condition and storage temperature to ensure its quality. In this study, the beef steaks were stored at 4°C under HiO2 modified atmosphere packaging (MAP) (78.8% O2 + 18.8% CO2 + 2.4% N2) and HiCO2 MAP (60.0% CO2 + 40.0% N2). The traditional air packaging (AP) and vacuum packaging (VP) were used as the controls. The total viable count (TVC), colour, water holding capacity (WHC), myofibrillar protein (MP) oxidation and lipid oxidation of beef meat were investigated. The moisture distribution and migration were also analysed using the low‐field nuclear magnetic resonance (LF‐NMR). The association amongst all parameters was analysed by correlation analysis and principal component analysis (PCA). The results showed that the TVC values in the HiCO2 MAP (5.6 log CFU/g) steaks were lower than those of VP (5.9 log CFU/g), AP (7.0 log CFU/g) and HiO2 MAP (6.3 log CFU/g) steaks because of the sufficient CO2 after 15 days of chilled storage. The bright red colour and the higher WHC were maintained in the HiO2 MAP steaks than in the AP group during storage. However, higher levels of protein and lipid oxidation also occurred. The beef steaks stored under HiCO2 MAP had the lowest protein and lipid oxidation and highest value of immobile water content and WHC, however, similar to the VP group, the bright red colour was not shown. The moisture attributes (drip loss, cooking loss and P23), protein oxidation (protein solubility and carbonyl content) and lipid oxidation (TBARS value) have shown a close correlation by correlation analysis and PCA. Overall, two different packaging methods of MAP can prolong microbial‐shelf life and maintain higher WHC of beef steaks compared to AP and VP steaks, but higher oxidation level in HiO2 MAP and unattractive colour in HiCO2 MAP are concerns that need to be addressed.

Sealing is a critical step in different packaging industries. In heat sealing as one of the major types of sealing processes, two layers of materials (typically thermoplastics) are joined together through the application of heat and pressure load for a certain sealing time. Due to the capabilities of the heat‐sealing process to seal different kinds and sizes of packages, it has a wide range of applications in many different industries such as the packaging of food and medical products. The quality and integrity of sealings produced by these techniques are crucial for the quality and safety of the contained materials. In this paper, different types and processes of sealing are discussed. Due to the variations in shape, size, and complexity of the sealing region, quality testing and inspection of these products is a challenging task. Nondestructive testing and evaluation (NDTE) techniques can be promising tools to overcome these challenges. Furthermore, a detailed study of various types of potential defects and their generation mechanism in heat sealing is presented. Then, various types of NDTE techniques that can be potentially used for the inspection of heat‐sealing regions and their working principles, as well as their strength and weakness in sealing inspection, are debated. Finally, several cases of sealing inspection and relevant NDTE techniques that are developed as standard procedures are presented. The discussions in this study provide useful information for the selection and implementation of appropriate quality inspection and inline quality monitoring of sealing parts and processes.
