    1. 3D Forming of Paperboard: The Influence of Paperboard Properties on Formability (pages 677–691)

      Alexey Vishtal, Marek Hauptmann, Roland Zelm, Jens-Peter Majschak and Elias Retulainen

      Article first published online: 11 DEC 2013 | DOI: 10.1002/pts.2056

      This article deals with the studying of the deformations of the paper-based materials in 3D-forming processes such as deep-drawing and thermoforming. The appearance and the depth of the 3D-shapes were linked with the mechanical properties of paper for understanding of deformation behavior.

    2. Using Graphene Oxide to Enhance the Barrier Properties of Poly(lactic acid) Film (pages 693–700)

      Graphene oxide (GO) is used as a barrier material to cooperate with polyethyleneimine (PEI) for electrostatic layer-by-layer assembly. And the nanoscale composite membrane of (PEI/GO)n has gotten poly(lactic acid) film an extraordinary barrier properties for oxygen gas.

    3. Finite Element Analysis of Hot Melt Adhesive Joints in Carton Board (pages 701–712)

      The aim of the present study is to analyse the behaviour of adhesive joints tested in the Y-peel testing device using a layered carton board model. It is found that the pre-peak behaviour of the Y-peel force-elongation curves is reasonably well captured by the FE simulations. The deformation and delamination pattern obtained in the simulations conforms to the observed behaviour during Y-peel testing at comparable loading levels, even though the delamination opening is somewhat underestimated by the model.

    4. Barriers Against the Migration from Recycled Paperboard into Food: Measuring Efficiency by Surrogate Components (pages 713–726)

      Sandra Biedermann-Brem and Koni Grob

      Article first published online: 4 FEB 2014 | DOI: 10.1002/pts.2062

      Functional barriers are likely to soon be required by certain countries to protect food against contaminants from recycled paperboard used for packaging. A method for specifying and checking the efficiency is described, using four surrogate compounds of different polarities. They are applied to a donor paper placed on one side of the barrier. On the other side, a silicone paper absorbs the material broken through the barrier. The performance of the method was tested on various barrier materials.

    5. An Extended Method to Measure Overall Consumer Satisfaction with Packaging (pages 727–738)

      Sandra Pousette, Martin Löfgren, Birgitta Nilsson and Anders Gustafsson

      Article first published online: 7 FEB 2014 | DOI: 10.1002/pts.2064

      A range of factors influences the success or failure of a product. This paper investigates the openability of packaged consumer goods. Results show that openability issues have a strong influence on the satisfaction evaluations of older consumers and are decisive for younger consumers.

    6. Effects of High Pressure Treatments on Polymeric Films for Flexible Food Packaging (pages 739–761)

      Lucia Sansone, Alessandra Aldi, Pellegrino Musto, Eugenio Amendola and Giuseppe Mensitieri

      Article first published online: 23 JAN 2014 | DOI: 10.1002/pts.2065

      This research addresses the issue of suitability of polymeric flexible packaging for use in high pressure pasteurization and sterilization. The effect of treatment conditions, up to 700 MPa and 115°C, on pouches containing foodstuff and made of several single layer and bilayer films, is analysed in terms of structural/morphological changes of polymer materials, of variation of functional properties and of delamination effects in bilayer structures.
