      Literature results on migration of photoinitiators in food packaging are reviewed and analysed in terms of an existing migration model based on diffusion and partition coefficients. Physicochemical properties of the photoinitiators, characteristics of the foodstuffs or food simulants, temperature, and packaging are concluded as the main factors affecting migration. This model also explains the reported efficiency of different plastic films as barriers to reduce migration. Published works concerning the suitability of polymeric multifunctional photoinitiators to print food packaging are considered.

    1. Applying Dynamic Thermography for Observation of Water Level in Column-Shaped Opaque Beverage Containers (pages 205–215)

      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. Corner Foam Versus Flat Foam: An Experimental Comparison on Cushion Performance (pages 217–225)

      This study applied the two most representative and correlated methods to evaluate both flat and corner foam. The study found that the static stress of the corner foam that occurred during the compression testing is 23% higher in average than the flat foam. The shock cushion curve of the corner foam shifted horizontally to the right as a result of the increased static stress. The authors recommend that the conventional cushion curve should be shifted to the right horizontally by about 23–35% in order for a packaging designer to apply it for corner foam.

    3. Impact Oscillator Model for the Prediction of Dynamic Cushion Curves of Open Cell Foams (pages 227–239)

      Article first published online: 5 SEP 2014 | DOI: 10.1002/pts.2100

      This paper delves into a qualitative understanding of the dynamics of a platen impacting an open cell foam cushion material. A hyperelastic material model is used to describe the foam's nonlinear stress-strain relationship, whereas its damping and hysteretic behaviour are represented with linear viscoelasticity. Using a simple nonlinear, discontinuous model of a drop test along with numerical simulations, the study examines the physics of the impact.

    1. Controlled Release of Mangiferin Using Ethylene Vinyl Acetate Matrix for Antioxidant Packaging (pages 241–252)

      Rungkan Boonnattakorn, Vanee Chonhenchob, Muhammad Siddiq and Sher Paul Singh

      Article first published online: 8 AUG 2014 | DOI: 10.1002/pts.2097

      This study investigated the use of ethylene vinyl acetate (EVA) matrix in controlled release packaging. Mangiferin was incorporated into the EVA matrix with different VA contents. The release rate of mangiferin increased with increasing VA content (decreasing crystallinity) and related to the antioxidant activity of the film.

    2. Issues with Combining Road Elevation Spectral Models and Vehicle Vibration Response to Estimate Vehicle Dynamic Characteristics (pages 253–270)

      Article first published online: 12 SEP 2014 | DOI: 10.1002/pts.2101

      This paper presents research into issues associated with the development of an experimental technique to establish the dynamic characteristics (frequency response function) of wheeled vehicles using only in-service response data. A single-wheeled prototype vehicle was designed and commissioned for the preliminary experiments and comparisons were made between the frequency response functions obtained from the laboratory and those established in-service (combining the measured response data with an assumed excitation spectral model).
