      The development of a film made of activated carbon and sodium erythorbate dispersed low-density polyethylene matrix is presented, which can be used for absorbing oxygen in gaseous environments such as the head space of food packages. This material was able to absorb up to 87% of the oxygen found inside a typical juice package. Furthermore, a thermal analysis of these particles showed satisfactory stability when subjected to temperatures corresponding to polymers manufacturing.

    1. Indirect Inverse Substructuring Theory for Coupling Dynamic Stiffness Identification of Complex Interface Between Packaged Product and Vehicle Transport System

      Jun Wang, Guohua Sun, Lixin Lu and Teik C. Lim

      Article first published online: 8 AUG 2014 | DOI: 10.1002/pts.2096

      Thumbnail image of graphical abstract

      This work is an extension of the inverse sub-structuring method previously proposed by Teik C. Lim for predicting the component-level frequency response functions (FRFs) and coupling stiffness from only system-level FRFs. The aim of the present work is to develop a new frequency response function (FRF)-based indirect inverse sub-structuring method without measuring system-level FRFs at the coupling DOFs for product transport system with special constraints of vibration excitation and/or measurement at the packaging interface. By enforcing the dynamic equilibrium conditions at the coupling coordinates and the displacement compatibility conditions, a closed-form indirect inverse sub-structuring method is derived based on the relationship of easy-to-monitor component-level FRFs and the system-level FRFs at the coupling coordinates. Finally, the method is validated by a lumped mass-spring-damper model, showing exact agreement. The suggested method may help to obtain the main controlling factors and contributions from the various structure-borne paths for product transport system. (Add Figure 5 here)

    2. Controlled Release of Mangiferin Using Ethylene Vinyl Acetate Matrix for Antioxidant Packaging

    1. Applying Dynamic Thermography for Observation of Water Level in Column-Shaped Opaque Beverage Containers

      Minoru Aoyagi, Takefumi Hiraguri and Takahiro Ueno

      Article first published online: 7 AUG 2014 | DOI: 10.1002/pts.2095

      Thumbnail image of graphical abstract

      A method for determining the water level in opaque beverage containers is described. In this method, rapid heating of the surface of the beverage containers by flash was followed by thermographic observation of the dynamic changes in surface temperature. The proposed observation method was used for a globe-type reflector in order to observe the water level clearly. The proposed method can successfully observed the water level in the opaque beverage containers.

    2. Migration of Cyclic Monomer and Oligomers from Polyamide 6 and 66 Food Contact Materials into Food and Food Simulants: Direct Food Contact

      Martin Heimrich, Hermann Nickl, Martin Bönsch and Thomas J. Simat

      Article first published online: 7 AUG 2014 | DOI: 10.1002/pts.2094

      Thumbnail image of graphical abstract

      Aqueous and ethanolic simulants revealed to be worst case for migration of caprolactam and cyclic PA oligomers from PA6 (and PA66) FCM. Unlike oligomers, caprolactam migration reached equally high levels for the simulant oil, too. Migration of cyclic oligomers (non-intentionally substances per definition) was in the mg kg−1 range, probably exceeding the limit of exposition of 0.09 mg/person/day for Cramer class III substances, derived from the threshold of toxicological concern (TTC) concept. Extrusion of granulate material to a packaging film led to an increase of the oligomer concentration in the polymer.

    3. The Effect of Concave Base Shape Elements on the Three Dimensional Forming Process of Advanced Paperboard Structures

      Marek Hauptmann, Sebastian Ehlert and Jens-Peter Majschak

      Article first published online: 9 JUL 2014 | DOI: 10.1002/pts.2089

      Thumbnail image of graphical abstract

      Three dimensional forming of paperboard to structures with concave shape sections at the bottom geometry is a challenge but turned out to be possible. In the concave geometry, considerable tensile load and strain appear in the material. The straining can be supported through a delivery of material from adjoining convex sections. The material displacement in concave sections causes parallel wrinkles in the wall showing that a defined reduction of stiffness through creasing in this section could improve the forming process.

    4. Use of Sodium Lactate and Modified Atmosphere Packaging for Extending the Shelf Life of Ready-to-Cook Fresh Meal

      D. Gammariello, A. L. Incoronato, A. Conte and M. A. Del Nobile

      Article first published online: 9 JUL 2014 | DOI: 10.1002/pts.2092

      Thumbnail image of graphical abstract

      The combined effects of sodium lactate and modified atmosphere packaging was used in order to extend the shelf life of a ready-to-cook fresh skewer. The microbial and sensory quality of ready-to-cook fresh skewer was monitored. An increase in the shelf life equal to about 83% was recorded for the skewer treated with a dipping of meat in 40% sodium lactate solution and packaging under modified atmosphere packaging (50%O2/30%CO2/20%N2).

    1. Evaluation of Static and Dynamic Cushioning Properties of Polyethylene Foam for Determining Its Cushion Curves

      By Guang Li, Vincent Rouillard and Michael A. Sek

      Article first published online: 6 JUL 2014 | DOI: 10.1002/pts.2090

      Thumbnail image of graphical abstract

      A dynamic factor function is defined and obtained from the analysis on the experimental data from compression and cushion tests. The deformation energy per unit volume is taken into consideration to make an estimate of the maximum strain and dynamic stress data in an impact, and the peak acceleration can be predicted from the compression data corrected for the dynamic effects by the dynamic factor function. Then, the cushion curves at almost every test condition, such as different drop heights or thickness of cushioning material, can be approximated by a specially developed computer code using Matlab. This research can assist in determining the accuracy of cushion curves for all variants of a particular cushioning material from the dynamic factor function and compression test data.

    1. New Methods for Quality Analysis of Deep-Drawn Packaging Components from Paperboard

      Malte Wallmeier, Marek Hauptmann and Jens-Peter Majschak

      Article first published online: 30 JUN 2014 | DOI: 10.1002/pts.2091

      Thumbnail image of graphical abstract

      This publication aims to measure quality criteria of deep-drawn cups made of paperboard. The number of wrinkles and the shape accuracy of deep-drawn cups are measured by using image analysis and surface scans. Experimental results are used for the verification of the methods and for the investigation of influences of main process parameters. The experiments show that high blankholder force leads to an increasing number of wrinkles and has a negative effect on shape accuracy.

    1. Reduced-order Modelling of the Linear Vibration Response of Expanded Polymer Cushion Material

      Gregory S. Batt, James M. Gibert and Mohammed Daqaq

      Article first published online: 17 JUN 2014 | DOI: 10.1002/pts.2086

      Thumbnail image of graphical abstract

      This manuscript examines the accuracy and convergence of a reduced-order model (ROM). The ROM is derived from an idealized packaging system consisting of a rod of polymer foam with an attached end mass. The work begins with an introduction to the complex cyclic softening and the viscoelastic and nonlinear stress-strain behaviour exhibited by expanded polymer foam. Approximate eigenvalues and frequency response functions are compared with both exact and experimental eigenvalues reported in literature.

    1. Exploiting Propolis as an Antimicrobial Edible Coating to Control Post-harvest Anthracnose of Bell Pepper

      Asgar Ali, Yee Zi Wei and Maysoun A. Mustafa

      Article first published online: 9 JUN 2014 | DOI: 10.1002/pts.2088

      Thumbnail image of graphical abstract

      Ethanolic extracted propolis (EEP) was prepared and applied as a coating material for bell pepper stored at 10°C. It was evaluated by assessing the natural-based coating's ability to inhibit mycelial growth of Colletotrichum capsici, causal agent of anthracnose, and maintain the quality of bell pepper. Application of EEP as a coating significantly reduced the incidence of anthracnose and contributed towards moisture retention of fruit, with the higher dilutions of EEP yielding better results.

    1. Nanomaterials: a Map for Their Selection in Food Packaging Applications

      Carmen Sanchez Reig, Antonio Dobon Lopez, Mercedes Hortal Ramos and Vicente Agustin Cloquell Ballester

      Article first published online: 3 JUN 2014 | DOI: 10.1002/pts.2076

      Thumbnail image of graphical abstract

      Building up a map based on the current state-of-the-art nanomaterials for food packaging applications is required. Furthermore, there is a need to classify them independently of their nature, the packaging material and the way they are integrated to this material. A classification of the latest advances in this field was made accompanied by applying Multi-Criteria Decision Analysis in order to find which are the most relevant and/or expected to be potentially applied nanomaterials in the area of food packaging.

    1. Estimation of the Dynamic Properties of Non-linear Packaging Materials Using a Reverse Multiple Input/Single Output Based Approach

      Matthew J. Lamb and Anthony J. Parker

      Article first published online: 29 MAY 2014 | DOI: 10.1002/pts.2084

      Thumbnail image of graphical abstract

      This paper discussed an approach that separates the linear contribution of the system's nonlinear frequency response function (FRF) using an optimised reverse multiple input/single output (RMISO) algorithm. Results from the analysis of well-controlled physical experiments, performed using nonlinear expanded polystyrene samples configured in an single-degree-of-freedom (SDoF) arrangement, are presented. The results suggest that the RMISO-based technique is able to provide an estimate of the linear component of the FRF, which allows traditional modal parameter extraction techniques to be used for the analysis of nonlinear cushioning systems.

      The Effect of Full Body Versus Partial Body Graphic Labelling on Beverage Packaging

      Toni Gomes, Rupert Andrew Hurley, Andrew Duchowski, Duncan Darby and Andrew Ouzts

      Article first published online: 28 APR 2014 | DOI: 10.1002/pts.2070

      Thumbnail image of graphical abstract

      The shelf impact of full versus partial body graphic labels on beverages was examined and evaluated through purchase selection and eye-tracking data. Data revealed that both label sizes drew an equivalent amount of visual attention; however, consumers selected partial body labels more often than full body labels, regardless of the flavour of the beverage or their age group. Paper presents a unique methodology of comparing attention between the two label styles on plastic beverage bottles.

    1. A Better Posture Strategy for Fingertip Force and Finger Coordination during a Daily Activity

      Chen-Yu Huang and Fong-Chin Su

      Article first published online: 28 APR 2014 | DOI: 10.1002/pts.2068

      Thumbnail image of graphical abstract

      This study found a better posture strategy for the young subjects to open a jar with the off-table posture while sitting, and this was also the best opening posture when comparing the overall torque in this work with that reported in previous studies, no matter whether subjects were standing or sitting, or whatever type of finger group was defined. However, the effect of grasp type and the middle, ring and little fingertip forces needs to be clarified in future studies.

    1. Talking about Torque: Measuring Pack Accessibility – a Review

      A. Yoxall and J. Rowson

      Article first published online: 24 APR 2014 | DOI: 10.1002/pts.2079

      Thumbnail image of graphical abstract

      This paper examines and compares the work undertaken by a series of researchers to measure human torque strength with respect to the access of jars such as those used for packaging. The aim of the paper is to compare the results and examine the reasons for any differences in those results. The paper recommends that packaging researchers must be more consistent in their experimental approach in future analyses to aid comparison of results and to facilitate a broader knowledge base.

    1. Carton Clamp Test Methodologies and the Effects on Load Containment and Retention

      Jay Singh, Tyler Blumer, Soma Roy and Koushik Saha

      Article first published online: 16 APR 2014 | DOI: 10.1002/pts.2080

      Thumbnail image of graphical abstract

      Currently, there are two test standards that provide lab-based forklift/clamp testing guidance - ISTA 3B and ASTM 6055. This study attempted to determine if carton clamps are capable and repeatable enough to provide consistent data. It examined the test methodologies' effect on load containment and load retention and the effects of ride height and driver interaction. It also sought to understand if these effects are uniform across the unitized load or differ for various tiers of a palletized load.

    1. The Effect of Stretch Wrap Prestretch on Unitized Load Containment

      Jay Singh, Evan Cernokus, Koushik Saha and Soma Roy

      Article first published online: 16 APR 2014 | DOI: 10.1002/pts.2083

      Thumbnail image of graphical abstract

      The three main factors affecting the stability of a palletized load that is unitized by stretch wrapping mechanism are the type of unitized load, wrapping configuration and shipping method. The study showed that containment force is generally higher at the top and bottom than the middle section of the unitized load. There is no evidence suggesting an association between initial containment force and different levels of prestretch.

      Josep Pasqual Cerisuelo, Rafael Gavara and Pilar Hernández-Muñoz

      Article first published online: 16 APR 2014 | DOI: 10.1002/pts.2078

      Thumbnail image of graphical abstract

      Ethylene vinyl alcohol (EVOH) coatings with carvacrol, citral, marjoram, or cinnamon bark essential oil, on polypropylene PP and polyethylene terephthalate PET substrates, were subjected to diverse physicochemical analyses to assess their suitability for food packaging applications. The application of corona discharge followed by polyethyleneimine-primer provided excellent anchorage between EVOH and polypropylene PP or polyethylene terephthalate PET. The retention of active agents into EVOH matrices ranged from low to moderate, depending on the embedded substance. The inclusion of bentonite nanoparticles into EVOH substantially enhanced the performance of the final packages.

      Article first published online: 19 FEB 2014 | DOI: 10.1002/pts.2066

      Thumbnail image of graphical abstract

      Gas permselective plastic films have been in a great deal of attention in the area of modified atmosphere packaging of fresh produces; thus, in this study, the films with high ethylene permselectivity were developed and fabricated by blown film extrusion. Particularly high ethylene permselectivity was obtained from the films containing phenyl-grafted zeolites. An improvement of particle-polymer interface and interactions between double bonds of the phenyl group and ethylene gas may facilitate ethylene gas transports.

    4. Migration Processes of Metal Elements from Carbon Steel Cylinders to Food Gases

      Article first published online: 19 FEB 2014 | DOI: 10.1002/pts.2069

      Thumbnail image of graphical abstract

      This study presents a protocol for sampling and analysis of metal elements migrating from carbon steel cylinders to CO2, N2 and O2 employed by food and beverage industries, based on the use of an acidified trapping solution coupled with inductively coupled plasma mass spectrometry analysis. Our tests show that the concentrations of metallic elements (e.g. Al, Fe, Ni and Zn) as a result of migration processes occurring in 5 years are too low to significantly affect the quality of food gases.
