2021 European PLACE Virtual Conference

Shedding More Light on Barrier Performance

A comprehensive look into packaging material expectations, recyclability and barrier solutions

The Event took place on Tuesday, 19 October 2021 | 9:00 - 11:00 AM (ET)


  • Does Your Package Meet the Shelf Life Requirements Your Packaging Material Promises presented by Andreas Roos, Ametek
    There are many factors influencing the shelf life of a package food product. In particular, oxygen and water vapour. This presentation shows comparative case studies of both flat packaging materials and finished packages, highlighting differences in barrier caused by defects and also with regard to the influence of seal seams, corners and closures.


  • Barrier Concepts: Paving the Way (or Path) for Recyclability presented by Esra Kucukpinar, Materials Development, Fraunhofer Institute for Process Engineering and Packaging IVV, Freising, Germany 
    For the packaging of many sensitive foods, materials with high gas barrier performance are required. Additional barrier materials are used in plastic-based packaging because commodity polymers lack these qualities. Using these barrier materials in higher fractions makes recycling more challenging. To find an effective way out, current research aims towards the redesign of multi-material flexible packaging to mono-materials. This presentation discusses different barrier technologies. On one hand, there are structures based on vacuum deposition of Al or SiOx. On the other, there is the new option with a polyvinyl alcohol-based nanocomposite. All suggested structures are recyclable according to CEFLEX guidelines.


  • Flexible Packaging High Barrier Laminate Structures - The Market Changes: Barrier Film or Barrier Paper? presented by Davide Pomati*, Bobst Italia
    Until now, there has been much talk about changing the face of packaging, but the time has come to define the objectives of flexible packaging. Today’s industry transformation is not about removing plastics, it is about creating new plastics. This presentation discusses different cases of paper-based alternatives for so-called mono material solutions.


  • Challenges in High Performance Extrusion Coating of Thin Aluminum Foil and Barrier presented by Guenter Schubert, Speira GmbH
    Nowadays thin aluminum foil is still widely used because it provides the best solution if an uncompromising barrier is required, for example in flexible packaging or together with cardboard for liquid packaging. In this presentation, typical defects in daily-used cardboard packages related to foil integrity are illustrated by means of cross-sectioning and SEM and their effect upon barrier performance is also evaluated.
