    1. A Review of Thermoplastic Composites Vapour Permeability Models: Applicability for Barrier Dispersion Coatings (pages 565–578)

      This review discusses the applicability of the permeability models available for thermoplastic composites to predicting the performance of barrier dispersion coatings for paper materials. Because of the parallel orientation and the similar length and widths of fillers used in barrier dispersion coatings, three dimensional models such as the Fredickson–Bicerano, the Gusev–Lustic, and the Moggridge are more suitable to predict relative permeability. Further experiments are required to validate the models under varied combinations of aspect ratio and the volume fraction of fillers.

    1. Choice of Life Cycle Assessment Software Can Impact Packaging System Decisions (pages 579–588)

      Evaluation of several model packaging systems using COMPASS, SimaPro, GaBi, and Package Modeling software found significant discrepancies in LCA results. Given a common set of basic packaging containers as input, results from the LCA software systems studied disagreed on which container had the greatest environmental impact, and in some cases, impact indicators were more than an order of magnitude different between software. For LCA to be useful in guiding packaging design, this issue must be fully understood and resolved.

    2. Development of Films of Novel Polypropylene based Nanomaterials for Food Packaging Application (pages 589–602)

      Z. Ayhan, S. Cimmino, O. Esturk, D. Duraccio, M. Pezzuto and C. Silvestre

      Article first published online: 23 MAR 2015 | DOI: 10.1002/pts.2126

      New antimicrobial nanocomposite films of polypropylene random copolymer (PPR), PPR/Poly-β-pinene (PβP), PPR/clay, and PPR/PβP/clay were prepared by melt extrusion for food packaging application. Structural, morphological, and mechanical barrier; antimicrobial properties; and thermal stability of the films were determined. The incorporation of both clay and PβP increased thermal stability and tensile mechanical properties of PPR and improved barrier and antimicrobial properties compared with plain PPR.

    3. Packaging's Role in Minimizing Food Loss and Waste Across the Supply Chain (pages 603–620)

      Karli Verghese, Helen Lewis, Simon Lockrey and Helén Williams

      Article first published online: 9 APR 2015 | DOI: 10.1002/pts.2127

      Opportunities to reduce or recover food loss and waste through improved packaging were explored. For fresh produce, these include packaging that improves product protection, ventilation and temperature control; improved design of distribution packaging to reduce damage in transport and handling; and design of primary packaging considering demographic and lifestyle to reduce waste in the home. In some cases, a focus on reducing food waste will require more rather than less packaging. Packaging developers must therefore consider the product and its packaging as a complete system to optimize sustainability.

      The Effect of Laser Power, Traverse Velocity and Spot Size on the Peel Resistance of a Polypropylene/Adhesive Bond (pages 621–632)

      C. Dowding, R. Dowding, F. Franceschini and J. Griffiths

      Article first published online: 17 APR 2015 | DOI: 10.1002/pts.2128

      This work conducts empirical analysis of the polymer packaging seal-peel resistance response to three laser variables: power, incident traverse velocity and incident spot diameter. Analysis of these relationships has yielded an empirical relation that has been used to generate a predictive tool for users to establish operating windows given known process requirements. This work details an experimental approach that is of use for all polymer material combinations.

    5. Antifungal Activity of Crude Extracts of Coffee and Spent Coffee Ground on Areca Palm Leaf Sheath (Areca catechu) Based Food Packaging (pages 633–645)

      This study observed the antifungal activity of crude coffee extract (CCE) and crude spent coffee ground extract (CSCGE) against Aspergillus, Penicillum and Eurotium on the surface of an areca palm leaf sheath (Areca catechu). The extraction of CCE and CSCGE could be performed twice to obtain extracts containing aromatic compounds such as caffeine capable of inhibiting mould growth on an areca palm leaf sheath.

    6. Carnauba Wax and Modified Atmosphere in Refrigerated Preservation of ‘Tahiti’ Acid Limes (pages 647–656)

      Article first published online: 17 APR 2015 | DOI: 10.1002/pts.2133

      Peel yellowing and loss of mass of acid limes reduce its useful life. We tested the use of wax and different packaging to prolong the postharvest preservation. The combined use of wax and plastic Cryovac® D-955 or Vegetal Pack® films reduced the loss of mass and maintained the green peel color and the chemical characteristics. Low density polyethylene (LDPE) and Xtend® packaging resulted in high concentrations of acetaldehyde and ethanol, especially LDPE, which also misread the pulp color and led to alcohol odor.
