      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 (pages 15–30)

      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.

    2. Estimation of the Dynamic Properties of Non-linear Packaging Materials Using a Reverse Multiple Input/Single Output Based Approach (pages 31–45)

      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.

    3. Evaluation of Static and Dynamic Cushioning Properties of Polyethylene Foam for Determining Its Cushion Curves (pages 47–57)

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

      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. Mineral Oil Barrier Testing of Cellulose-Based and Polypropylene-Based Films (pages 75–89)

      Recycled cardboard has been identified as a major source of mineral oil contamination of foods. This paper shows that cellulose-based films and both-sided proprietary acrylic-coated biaxially orientated polypropylene film types can provide functioning mineral oil barriers within recycled cardboard packaging.

    1. Reduced-order Modelling of the Linear Vibration Response of Expanded Polymer Cushion Material (pages 59–74)

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

      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.
